NoOps é aplicável a sua organização?

Em 2011, a Forrester já publicava um artigo sobre NoOps e como a automação de algumas operações – build, deploy, testes, etc. levaria mudanças as equipes de infra, reduzindo a necessidade de interação com outras equipes e até mesmo da redução de recursos, substituídos por estes processos automatizados.

Claro que, após todos estes anos, e com os resultados obtidos pela disseminação do DevOps (foco na colaboração entre os times e automação) nas organizações, vimos que não é simples e tampouco mágica manter uma área de operações “rodando” em automático. E por isso, hoje o drive está muito relacionado ao trabalho eficiente, melhorando os resultados obtidos pela automação e forma de atuação no trabalho.

Agora em 2019, talvez o conceito de que DevOps possui foco em colaboração e NoOps em automação esteja mudando, pois é mesmo possível automatizar todas as tarefas de infraestrutura? E nas práticas DevOps já não existe forte colaboração entre os times mesmo com automação de inúmeros processos?

Aplicabilidade

Neste novo patamar atingido por serviços Cloud, os recursos podem ser abstraídos da infraestrutura subjacente, e as atividades de provisionamento e implantação de infraestrutura agora são gerenciadas por meio de serviços de infraestrutura e plataforma sob demanda.

O NoOps segue então como tendência ao ambiente que seja automatizado e abstraído da infraestrutura, podendo ser gerenciado por equipes menores e eficientes. Torna-se impossível viabilizar operações em grande escala com execução manual de atividades. A Deloitte Insights traz análises de adoção nas organizações.

É então mais recomendável a ambientes de TI homogêneo com pouca diversidade no nível da infraestrutura. O stack diversificado de tecnologia (aplicações e infraestrutura) e o comum histórico das mudanças no nível de infraestrutura (dinâmicas e distribuídas) tornam muito mais complexa a adoção NoOps nestes ambientes.

DevOps e NoOps

DevOps (by Microsoft) “É a união de pessoas, processos e produtos para permitir a entrega contínua de valor aos nossos usuários finais. A contração de “Dev” e “Ops” refere-se à substituição do Desenvolvimento e Operações em silos para criar equipes multidisciplinares que agora trabalham em conjunto com práticas e ferramentas compartilhadas e eficientes. As práticas essenciais do DevOps incluem planejamento ágil, integração contínua, entrega contínua e monitoramento de aplicativos”.

NoOps significa nenhuma operação. O foco é automatizar todas as tarefas de manutenção associadas ao desenvolvimento e à execução de uma solução. Isso não é uma missão simples, mas possível, considerando que os provedores de serviços terceiros podem executar tarefas de implantação, gerenciamento e manutenção, tal como o EKS da Amazon. E assim, não há necessidade de alta interação entre os times para tornar possível a conclusão do trabalho.

Os provedores de nuvem continuam subindo o stack, assumindo muitas tarefas de administração de sistemas, tais como aplicação de patches, backup e gerenciamento de banco de dados, entre outras.

Traditional Ops e NoOps

As operações de TI não desaparecem apenas com a adoção de plataformas em cloud  pública. Entre algumas evoluções na gestão operacional:

  • Automação: na maior parte das tarefas operacionais, sendo norma e não mais exceção.
  • Proativo: o uso de informações preditivas orientadas por IA para monitorar e otimizar serviços de TI, para que as equipes de Ops possam se concentrar em iniciativas voltadas para o cliente.

Na prática

Além das considerações de aplicabilidade (citadas anteriormente) em relação a manutenção e ambientes legados, outro ponto de atenção é a absorção de novas atividades aos desenvolvedores. Além do interesse em administrar suas próprias soluções, vale verificar o processo para não gerar gargalos.

Como NoOps é habilitado por tecnologia, existem algumas opções PaaS como Heroku e serviços cloud na AWS e Azure. Serverless computing e replicable infrastructure são também boas soluções para resolver a parte da infraestrutura e as ferramentas tradicionais de implantação.

DevOps, Ikigai, Gamificação e F4P – despertando o propósito no CI/CD

O acordo do time é essencial para alavancar as entregas contínuas orientadas a valor. Como orquestrar então “processos – pessoas – ferramentas” neste contexto? Utilizando conceitos do Ikigai, Gamificação e Fit For Purpose (F4P), este trabalho demonstra como equilibrar o compromisso das entregas com o que gostamos de fazer. Também compartilha os resultados obtidos com a transformação cultural, envolvendo as boas práticas de desenvolvimento, o comprometimento com CI/CD e a gestão ágil.

Link de acesso do material: Agile Trends 2019 – Leonardo Matsumota.

  • Ikigai: contextualização da filosofia e correlação entre o ser humano e seu trabalho, em busca do propósito entre paixão, missão, profissão e vocação.
  • F4P: utilização do F4P Card (adaptado), Fitness Box Score e Matriz (aderência x identidade) para identificar a satisfação dos colaboradores com a empresa.
  • Hard Skill Canvas: traz alinhamento, transparência e melhoria contínua ao time, conhecendo as competências técnicas que o time precisa para os produtos da organização.
  • Engajando CI/CD: senso de pertencimento, cadência e gestão.
  • Gamificação: ampliando as boas práticas com senso de colaboração e conhecimento.
  • Formato de trabalho: Squads, OKRs e camadas de engajamento.

 

Digital Engagement- Sistema de registro e engajamento

Continuando a abordagem do Bi-modal Gartner, outro conceito importante e mencionado no livro The DevOps Handbook é o Sistema de registro e engajamento. Entre os quatro fluxos de valor estão:

  • Serviço virgem: uma nova iniciativa de software.
  • Serviço abandonado: produtos que já atendem a clientes e estão no mercado há anos.
  • Sistema de registro: centralizados para gerenciar uma única fonte de dados na organização. Contém todo o suporte para a entrega de valor ao cliente . Inclui o gerenciamento dos dados, transações, segurança e privacidade.
  • Sistema de engajamento: interage diretamente com o cliente. Incentivam a interação dos clientes e usuários com a organização por meio de apps, portais colaborativos, etc.

E assim, segundo o conceito de TI Bimodal de Gartner (prática de administrar dois estilos de trabalho separados, mas coerentes: um focado na previsibilidade, o outro na exploração), classifica o sistema de registro e engajamento na seguinte tabela:

Sistema Tipo Bimodal Ritmo de mudanças
Registro Modo 1: fazer direito com foco em estabilidade e confiabilidade Mais lento e costumar ter requisitos normativos e conformidade
Engajamento
Modo 2: fazer rápido com foco em flexibilidade e inovação Mais rápido e permite experimentos em ambientes incertos

Enquanto no sistema de registro, a vantagem é lidar com tarefas burocráticas e demoradas, como conformidade, segurança e privacidade (por exemplo utilizando a telemetria e automação para gerar as evidências), por outro lado, o sistema de engajamento demonstrará a confiabilidade da inovação em ciclos de entregas rápidos, por exemplo, novas funcionalidades que melhoraram a conversão de clientes em 40% no e-commerce da empresa.

Samoore contextualiza que o engajamento digital certamente inicia com os sistemas de engajamento (as tecnologias que permitem aos usuários interagir com a organização), conectando aos sistemas de registro que mantêm os dados sobre a pessoa e sua história com a organização. Os sistemas de insight por fim executam as análises para apoiar essa individualização e tornar a interação relevante.

DevOps – Pipeline de implantação, CI (Continuous Integration) e CD (Continuous Delivery)

Em geral, o processo organizacional para lançamento de um produto (ou nova funcionalidade) no mercado segue as seguintes etapas:

  1. Visão do produto: definição das funcionalidades do produto
  2. Time de Dev: realiza o desenvolvimento de forma iterativa e incremental; uma nova versão a cada iteração
  3. Área de operação: implementa e mantém os ambientes estáveis
  4. Monitoramento e retorno: geração do valor e uso pelo cliente

O Fluxo de valor, desde a concepção do produto até a geração de valor, analisa o caminho completo de criação de valor e compreende o valor exato adicionado em cada parte. Em métodos ágeis, não há prescrição dos aspectos da entrega, e por isso, a última milha é regida por boas práticas para cobrir todo o processo da implantação.

O feedback vai guiando a estratégia da empresa, eliminando barreiras entre os departamentos e permitindo a colaboração entre as pessoas para gerar valor ao cliente.

pipeline-implantacao

Um pipeline de implantação é uma manifestação automatizada do seu processo para levar o software do controle de versão para as mãos de seus usuários. Todo o processo – do conceito ao dinheiro – pode ser modelado como um mapa de fluxo de valor. Envolve os processos de

  • Integração Contínua
  • Entrega Contínua
  • Implantação Contínua

CI-CD

Criando um pipeline de implementação (imagem abaixo no Azure DevOps):

  1. Modelar o fluxo de valor, criando um esqueleto do processo
  2. Automatizar os processos de compilação e testes
  3. Automatizar os processos de implantação
  4. Implantar a estratégia de entrega de versão

pipeline-implantacao-azure-devops.png

  • Envolver qualidade e segurança da informação desde o início
  • Estratégia de testes, considerando teste unitário, integração, segurança, TDD/BDD/ATDD, infraestrutura e performance
  • Telemetria eficiente na coleta e monitoramento das informações

CI (Continuous Integration)

São práticas que encorajam os desenvolvedores a integrar o seu trabalho continuamente – um novo código fonte (branch ou trunk) ao principal (main). Permite ajustes frequentes nos códigos, entregas rápidas e com menos bug. Há três coisas que você precisa estar ciente antes de CI:

  1. Controle de versão
  2. Build automatizado
  3. Acordo do time

Alguns pré-requisitos da CI:

  • Check in frequente
  • Suíte de testes abrangente
  • Manter o processo de Build e Teste curto
  • Gerenciando seu workspace de desenvolvimento

CI é uma prática, não uma ferramenta, e por isso, depende da disciplina para torna-la efetiva. Algumas práticas recomendadas para as equipes:

  • Builds devem passar no coffee test (menos de 5 minutos)
  • Não fazer check in de build com falha
  • Sempre execute todos os testes de confirmação antes do commit
  • Não vá embora com um build quebrado
  • Esteja sempre preparado para reverter a revisão anterior
  • Defina um time box antes de reverter (por exemplo: 10 minutos se não obtiver a solução, reverter a revisão anterior)
  • Test-Driven Development

Jez Humble: “The goal of continuous integration is that software is in a working state all the time”.

Continuous Delivery

É uma extensão do CI para garantir que novas modificações estejam disponíveis para serem implementadas no ambiente de produção.  Os testes e o processo de liberação são automatizados e contribuem com o controle de qualidade para prover feedbacks rápidos aos desenvolvedores.

O deploy para produção não é automático, porém pode ser realizado a qualquer momento, dependendo do aceite da alteração (com o clique de um botão).

Boas práticas:

  • Build somente uma vez o artefato (rebuild – passará novamente por todos os ambientes; quebrará sua auditoria)
  • Artefatos devem ser imutáveis (armazenados com restrição de permissão). Manter os acessos de deployers somente onde deve ter acesso
  • Duas boas razões para ser imutáveis: a) cria confiança entre o time b) ser rastreável (poder verificar versões específicas, etc.)
  • Deployment deve ir para uma cópia de produção; pare o deploy se uma etapa anterior falhar
  • Deployments devem ser idempotente

Métricas do seu pipeline:

  • Você é capaz de auditar uma simples mudança?
  • Quão rápido você pode mover uma mudança para produção?
    (overall cycle time)
  • Cycle time = do check-in até produção

Continuous Deployment

Processo sem intervenção humana, realizando todas as validações anteriores para disponibilizar a nova modificação em produção automaticamente. Somente uma falha encontrada nos testes impede a implementação em produção.

Neste processo é muito importante validar com a área de segurança da informação e compliance da sua empresa a aplicabilidade deste processo. Em operações críticas que trabalham com deploys contínuos (dezenas, centenas ou milhares por dia), torna-se inviável gerenciar este processo sem ter a implantação do Continuous Deployment.

Gestão de backlog – Epic Roadmap, WI relationships e personas no Azure DevOps

Já discutimos sobre o uso do Azure DevOps como plataforma de ciclo de vida do desenvolvimento e a estruturação do backlog na ferramenta (Epic – Feature – User Story – Tasks) de acordo com o seu process template.

Na área de Boards do Azure DevOps, temos alguns novos recursos no Marketplace para apoiar a visualização e gestão das atividades dos times. Selecionei três deles que são bem interessantes:

Crie então a estrutura do seu Time de Projeto no Azure DevOps (Boards > Backlogs). Veja na imagem abaixo que a relação entre Epic – Feature (Requirement) – User Story é de Parent. 

azure-devops-backlog

Feature timeline and Epic Roadmap

Após a estruturação do backlog, ainda em Boards > Backlogs, veja que as guias de “Feature Timeline” e “Epic Roadmap” foram criadas (após a instalação da extensão do Marketplace). A visão é das User Stories em relação a Sprints que serão desenvolvidas. Este roadmap ajuda o time a visualizar a entrega das funcionalidades do projeto.

epic-roadmap

Visualize work item relationships

Após a instalação da extensão no Marketpace, acesse as opções do Work Item (conforme imagem abaixo) e utilize Visualize. Em seguida, veja que será exibido a estruturação do seu backlog, bem semelhante ao FBS (Feature Breakdown Structure), muito utilizado para ajudar o time a melhorar a compreensão do produto e requisitos.

wi-visualization

Personas

Por fim, a criação de Personas ajuda a representar o usuário no sistema, descrevendo seu papel e necessidades. Instale a extensão do Marketplace (conforme link no início do artigo) e acesse o novo recurso “Personas” que será exibido, conforme abaixo.

Clique em + Add para adicionar uma nova Persona. Preencha o Nome, Tag, Descrição e Foto conforme necessidade do projeto.

Book Review: “Lean Enterprise: How High Performance Organizations Innovate At Scale”

Book Review: “Lean Enterprise: How High Performance Organizations Innovate At Scale” (Jez Humble, Joanne Molesky, Barry O’Reilly)


PART I: ORIENT

Chapter 1 – Introduction
Starts explaining the importance of management and people and an approach in Toyota Production System. An alternative to command and control and other highlighted topics are:

A Lean Enterprise is primarily a human system:

  • Pathological organizations: are characterized by large amounts of fear and threat. People often hoard information or withhold it for political reasons, or distort it to make themselves look better.
  • Bureaucratic organizations: protect departments. Those in the department want to maintain their “turf”, insist on their own rules, and generally do things by the book – their book.

How organizations process information:

Pathological (power-oriented) Bureaucratic (rule-oriented) Generative (performance – oriented)
Low cooperation Modest cooperation High cooperation
Messengers shot Messengers neglected Messengers trained
Responsibilities shirked Narrow responsibilities Risks are shared
Bridging discouraged Bridging tolerated Bridging encouraged
Failure leads to scapegoating Failure leads to justice Failure leads to enquiry
Novelty crushed Novelty leads to problems Novelty implemented

The three gaps, and how to manage them:

Effects gap Knowledge gap Alignment gap
What is it? The difference between what we expect our actions to achieve and what they actually achieve The difference between what we would like to know and what we actually know The difference between what we want people to do and what they actually do
Scientific Management Remedy More detailed controls More detailed information More detailed instruction
Auftragstaktik remedy “Everyone retains freedom of decision and action within bounds” “Do not command more than is necessary or plan beyond the circumstances you can foresee” “Communicate to every unit as much of the higher intent as is necessary to achieve the purpose”
Directed opportunism remedy Give individuals freedom to adjust their actions in line with intent Limit direction to defining and communicating the intent Allow each level to define how they will achieve the intent of the next level up, and “backbrief”

The key to the Principle of Mission is to create alignment and enable autonomy by setting out clear, high-level target conditions with an agreed time frame. This principle is applied in multiple contexts:

  • Budgeting and financial management
  • Program management
  • Process improvement

 

Chapter 2 – Manage the Dynamics of the Enterprise Portfolio

This chapter explain the lifecycle of businesses and how companies can balance the exploration of new business models with the exploitation of proven ones.

Technology adoption lifecycle

Technology adoption lifecycle

Once the market has assimilated a disruptive new technology or idea, a whole range of product offerings gets spawned.

Exploring new opportunities and exploiting existing ones are fundamentally different strategies requiring different structure, competencies, processes, and mindset. It is hard to overemphasize this key point: management practices that are effective in the exploit domain will lead to failure if applied to exploring new opportunities – and vice versa. The difference between these two domains:

Explore Exploit
Strategy Radical or disruptive innovation, new business model innovation Incremental innovation, optimizing existing business model
Structure Small cross-functional multiskilled team Multiple teams aligned using Principle of Mission
Culture High tolerance for experimentation, risk taking, acceptance or failure, focus on learning Incremental improvement and optimization, focus on quality and customer satisfaction
Risk management Biggest risk is failure to achieve product / market fit A more complex set of trade-offs specific to each product / service
Goals Creating new markets, discovering new opportunities within existing markets Maximizing yield from captured market, outperforming competitors
Measure of progress Achieving product/market fi Outperforming forecasts, achieving planned milestones and targets

Exploring New Ideas

Less than 50% of startups are alive five years after they start. The Lean Startup details a method for working in conditions of extreme uncertainty – to discover and operationalize new and potentially disruptive business models, and quickly discard those that will not work.

Every entrepreneur has a vision of their business. And for this vision to become reality, there are two key assumptions that must be tested:

  • Values hypothesis: asks whether our business actually provides value for users by solving a real problem.
  • Growth hypothesis: tests how fast we can acquire new customers and whether we have that.

Investing a fixed amount of time and money to investigate the economic parameters of and idea-be it a business model, product, or an innovation such as a process change-is an example of using optionally to manage the uncertainties of the decision to invest further. We limit our maximum investment loss (“downside”) on any individual idea, with the expectation that a small number of ideas will pay off big time, and offset or negate investment in those that did not.

The principle of optionality
The principle of optionality

The other part in this chapter is related to Enterprise Portfolio – balancing (using an economic model), matrix portfolio management (1. Emerging 2. Growth 3. Mature 4. Decline), managing a portfolio with the three horizons model (1. Current Business 2. High Growth Businesses 3. Growth Options).

 

PART II: EXPLORE

Chapter 3 – Model and Measure Investment Risk

Here is presented the principles and concepts that enable us to take a systematic approach to managing the risk of planned work, by gathering information to reduce uncertainty. Model Investment Risk using Business Case or Monte Carlo are discussed in this chapter to verify how useful they are in scenarios of uncertainty.

We should stop using the word “requirement” in product development, at least in the context of nontrivial features. What we have, rather, are hypotheses. In the case of business model and product innovation, the Lean Startup movement provide us with a framework for operating in conditions of extreme uncertainty:

  • Do not spend a lot of time creating a sophisticated business model. Instead, design a simplified business model canvas with captures and communicates the key operating assumptions of your proposed business model.
  • Gather information to determine if you have a problem worth solving.
  • Then, design an MVP (minimum viable product)-an experiment designed to maximize learning from potential early adopters with minimum effort.
  • Throughout this process, update the business model canvas based on what you learn from talking to customers and testing MVPs.

Traditional product lifecycle versus Lean Startup lifecycle:

Traditional project-planning process Lean Startup discovery process
What data do we have to make the investment decision? A business plan based on a set of untested hypotheses and assumptions, backed by case studies and market research Real data based on evidence complied from a working product or service tested with real customers
What happens next? We must create detailed requirements, if we haven’t already, and then starts a project to build, integrate, test, and finally release the system We already have a validated MVP which we can build upon immediately with new features and enhancements based on customer feedback
When do we find out if the idea is any good? Once the project is complete and the product or service is live We already have this evidence based on the data we have collected

Principles for exploration
The OODA loop, a model of how humans interact with their environment which forms the basis of Boyd’s theory of maneuver warfare. OODA stands for observe, orient, decide, act, the four activities that comprise the loop.

 

Chapter 4 – Explore uncertainty of detect opportunities

In the chapter four, tools and techniques are shared to safely create and test hypotheses to solve real business problems identified and validated in our customer development process. Discovery is a rapid, time-boxed, iterative set of activities that integrates the practices and principles of design thinking and Lean Startup, used intensively at the beginning of the explore phase of a new initiative.

Creating a shared understanding (Dan Pink – Drive):

  1. Success requires a shared sense of purpose in the entire team
  2. People must be empowered by their leaders to work autonomously to achieve the team objectives
  3. People need the space and opportunity to master their discipline, not just to learn how to achieve “good enough”

With workshops, you can co-create ideas aligned to business goals. The process, starting with divergent thinking until convergent thinking can generate multiple ideas for discussion and debate.

Structured exploration with divergent and convergent thinking

Structured exploration with divergent and convergent thinking

The Business Model Canvas can share the understanding about business problem to inform the Business Plan. It includes nine essential components of an organization’s conceptual business model – customer segment, value proposition, channels, activities, resources, partnerships, cost and revenue.

Business Model Canvas

In this chapter, also is covered MVPs and how to accelerate experimentation with them. Cagan defines an MVP “the smallest possible product that has three critical characteristics: people choose to use it or buy it; people can figure out how to use it; and we can deliver it when we need it with the resources available-also known as valuable, usable and feasible”.

Chapter 5 – Evaluate the product/market fit

This chapter discuss how to identify when a product/market fit has been achieved and how to exit the explore stage and start exploiting our product with its identified market. Also, how to use customized metrics to understand whether we are achieving measurable business outcomes while continuing to solve our customers problems by engaging them throughout our development process.

Some examples of vanity metrics and corresponding actionable metrics:

The pirate metrics helps you to model any service-oriented business. Measuring pirate metrics for each cohort allows you to measure the effect of changes to your product or business model, if you are pivoting. The Votizen’s pirate metrics represents the effect of incremental change and pivots.

A story map can help you to tell the narrative of the Runway of our vision. Can be used to plan e prioritize by visualizing the solution as a whole. It provides an effective means to communicate the narrative of our solution to engage the team and wider stakeholders and get their feedback.

The five critical enablers of growth when transitioning from explore to exploit are:

  • Market
  • Monetization model
  • Customer adoption
  • Forget “big bang” launches
  • Team engagement

 

PART III: EXPLOIT

Chapter 6 – Deploy Continuous Improvement

In most enterprises, there is a distinction between the people who build and run software systems and those who decide what the software should do and make the investment decisions. Ultimately, we aim to remove this distinction. In high performance organizations today, people who design, build, and run software-based products are an integral part of business.

In this chapter is described how to achieve the balancing (the work we do to improve our capability against delivery work that provides value to customers) at program and value stream levels, by putting in place a framework called Improvement Kata. The other part, covers practices in CI/CD as branching versus trunk-based development and other. For more details, I recommend to access my blog.

A good example, in the HP LaserJet Firmware Case Study, we can see how allocating costs to the activities the team is performing.

% of costs Activity
10% Code integration
20% Detailed planning
25% Porting code between version control branches
25% Product support
15% Manual testing
~5% Innovation

The Improvement Kata needs to be first adopted by the organization’s management, because it’s a management philosophy that focuses on developing the capabilities of those they manage, as well as on enabling the organization to move towards its goals under conditions of uncertainty. There are four stages that we repeat in a cycle:

The Improvement KataThe Improvement Kata

  • Understand the direction: derived from the vision set by the organization’s leadership.
  • Grasp the current condition: after the direction, we incrementally and iteratively move towards it at the process level.
  • Establish the next target condition: as we continuously repeat the cycle, we reflect on the last step taken to introduce improvement.
  • Iterate toward the target condition

Three years after the initial measurements (in HP LaserJet case), a second activity-accounting exercise offered a snapshot of the results the FutureSmart team had achieved with their approach:

% of costs Activity
2% Continuous integration
5% Agile planning
15% One main branch
10% Product support
5% Manual testing
23% Creating and maintaining automated test suites
~40% Innovation


Chapter 7 – Identify value and increase flow

Most enterprises are drowning in a sea of overwork, much of which provides little value to customers. In the previous chapter was showed how to implement a program-level continuous improvement strategy to improve productivity and quality and reduce costs. In this chapter, the purpose is showing how the five lean principles can be adopted to reduce the cycle time, increasing quality and return on investment.

In high-performing organizations, leadership and management has a sharp focus on the value the organization is creating for its customers.

The value stream map helps to reflect the current condition in a determined product or service we want to evaluate. This exercise must gather people from every part of organization involved in the value stream.

value stream mapOutline of a value stream map showing process blocks

After concluded, we record three key metrics:

  • Lead time: the time from the point a process accepts a piece of work to the point it hands that work off to the next downstream process
  • Process time: the time it would take to complete a single item of work if the person performing it had all the necessary information and resources to complete it and could work uninterrupted
  • Percent complete and accurate (%C/A): the proportion of times a process receives something from an upstream process that it can use without requiring work

Also is presented Kanban concepts to share a comprehensive way to manage the flow of work:

  • Visualize workflow (creating a board)
  • Limit WIP (work in progress)
  • Define classes of service (for different types)
  • Create a pull system (by agreeing on how work will be accepted into each process block when capacity becomes available)

And a Cost of Delay – a framework for decentralizing economic decisions, to identify and prioritize the work with the highest opportunity cost.

How do we prioritize Tasks A and B with Cost of Delay? 


Chapter 8 – Adopt Lean Engineering Practices

“Cease dependence on mass inspection to achieve quality. Improve the process and build quality into the product in the first place”. W. Edwards Deming.

In this chapter there are important concepts to allow the organizations deploy new releases in production frequently, necessary to test ideas with real users and enable effective innovation process (learn and update based on feedback). For more details from other concepts like continuous integration, test automation, continuous deliver and deployment pipeline, access my blog.

Chapter 9 – Take an Experimental Approach to Product Development

Up to now, the others chapters show how to improve the speed at which can deliver value to customer. In this chapter, the focus is to discuss alignment – how to use capabilities we have developed to make sure we are building the right things for customers, users, and our organization.

So, concepts as creating hypothesis, hypothesis-driven development and user research are described to focus on the outcomes we wish to achieve, rather than solutions and features.

Chapter 10 – Implement Mission Command

The organizational and architectural concerns are often the biggest barriers to executing the strategy for moving fast at scale based on the principles of Mission Command (described in Chapter 1). Amazon has a famous memo to technical staff directing them to create a service-oriented architecture:

  • All teams will henceforth expose their data and functionality through service interfaces
  • Teams must communicate with each other through these interfaces
  • There will be no other form of interprocess communication allowed. The only communication allowed is via service interface calls over the network
  • It doesn’t matter the technology they use. HTTP, Corba, Pubsub, custom protocols.
  • All services interfaces, without exception, must be designed from the ground up to be externalizable
  • Anyone who doesn’t do this will be fired

A key principle of service-oriented architecture (SOA) is decomposing systems into components or services. Each component or service provides an interface (also known as an API – application programming interface) so that other components can communicate with it.

Here are some strategies enterprises have successfully applied to create autonomy for individual teams:

  • Give teams the tools and authority to push changes to production
  • Ensure that teams have the people they need to design, run and evolve experiments
  • Ensure that teams have the authority to choose their own toolchain
  • Ensure teams do not require funding approval to run experiments
  • Ensure leaders focus on implementing Mission Command

product teamsProduct teams working together, with a service layer for performing deployments

Creating small, autonomous teams makes it economic for them to work in small batches. When done correctly, this combination has several important benefits:

  • Faster learning, improved customer service, less time spent on work that does not add value
  • Better understanding of user needs
  • Highly motivated people
  • Easier to calculate profit and loss

 

PART IV: TRANSFORM

Chapter 11 – Grow an innovation culture

Culture is the most critical factor in an organization’s ability to adapt to its changing environment. The main topics in this chapter are:

  • Model and measure your culture: important to consider layers of organizational culture
    • Artifacts: visible, observable aspects of culture such as organizational structures and processes, and how people dress and behave. Hard to decipher.
    • Espoused values: strategies, goals, philosophies, such as the “value statements” you find in the company lobby
    • Underlying assumptions: unconscious beliefs, perceptions, thoughts, feelings (which ultimately govern values and behavior)
  • Change your culture: Old and new approaches to cultural change – Shook offers his own interpretation of Schein’s model, showing how people normally approach cultural change in contrast to the approach taken at NUMMI.
    Shook Change your culture
  • Make it safe to fail
  • There is no talent shortage: Dweck’s two mindsets, showed through a series of experiments that our mindset determines how you decide your goals, how to react to failure, what are our beliefs about effort and strategies, and what is our attitude towards the success of others.

Chapter 12 – Embrace Lean Thinking for Governance, Risk and Compliance

The chapter is to guide you through the maze that is GRC (Governance – Risk – Compliance), particularly as it relates to managing the concepts and practices required to be a lean enterprise. Governance is about keeping our organization in course. It is the primary responsibility of the board of directors, but it applies to all people and other entities working for the organization. It requires the following concepts and principles to be applied at all levels:

  • Responsibility
  • Authority and accountability
  • Visibility
  • Empowerment
  • Risk management and compliance

Apply Lean Principles to GRC processes: visualizing the value stream, increasing feedback, amplifying learning, empowering teams, reducing waste and delays, limiting work in process, making small incremental changes, and continuously improving to achieve better outcomes.

Good Governance requires everyone to focus on discovering ways to improve value and provide accurate information on which to base our decisions. We start with leadership and direction from the Board and Executives, and rely the ability of employees to embrace their responsibility to make good decisions at work. A culture of openness, trust, and transparency is required for good governance.

 

Chapter 13 – Evolve Financial Management to drive Product Innovation

Centralized budgeting process are typically used to plan, forecast, monitor and report on the financial position and overall performance of an organization. However, the traditional annual budget cycle can easily:

  • Reduce transparency
  • Remove decision from the people doing the work
  • Direct costs away from value creation
  • Measure performance by the ability to please the boss or produce output

Approaches to achieving the goals of budgeting

The Dynamic Resource Allocation creates more frequent checkpoints for funding decisions, and each decision has less risk associated with it. All decisions are based on the empirical evidence, so they become easier to make. When done correctly, access to funding expands to more teams, gets more frequent, has less associated risk, and brings better results. We thus encourage more innovation and reduce financial risk associate with large initiatives.

In the other part, the chapter describe:

  • Avoid using budgets as the Basis for performance measurement: bonuses and rewards for good bottom-line financial results work better when they are shared equally. Working teams will eventually cripple the organization by inertia and subterfuge when their contributions are not acknowledged and rewards are based on a process perceived as unfair.
  • Stop basing business decisions on CAPEX versus OPEX: there are tax advantages and positive financial impacts from reporting organization expenditures appropriately in these different buckets, so a lot of attention is paid to it.
  • Modify your IT Procurement Processes to gain greater control over value delivery: this painful, highly detailed contractual process has several negative side effects
    • It’s a poor way to manage the risks of product development
    • It favors incumbents
    • It favors large service providers
    • It inhibits transparency
    • It is inaccurate
    • It ignores outcomes

 

Chapter 14 – Turn IT into a competitive advantage

This chapter is discussed some strategies to increase the responsiveness of IT to changing business needs, improve the stability of IT services, and reduce the complexity of our IT systems and infrastructure.

Rethinking the IT Mindset: IT has historically been seen as a cost center and an internal enabler of the business, not a creator of competitive advantage. In the 2014 State of DevOps Report, over 9,000 people worldwide were polled about what creates high-performance organizations, whether IT does in fact matter to the business, and what factors impact the performance of IT departments.

rethinking it mindsetWhat business leaders think about the business-IT relationship

The practices most highly correlated with high IT performance (increasing both throughput and stability) are:

  • Keeping systems configuration, application configuration, and application code in version control
  • Logging and monitoring systems that produce failure alerts
  • Developers breaking up large features into small, incremental changes that area merged into trunk daily
  • Developers and operations regularly achieving win/win outcomes when they interact

If we want to compete in a world of ever shorter product cycles, central IT needs to be business unit’s trusted partner, not an order-taking cost center. In turn, IT needs to achieve higher levels of throughput while improving stability and quality and reducing costs. The complexity of existing enterprise IT environments, combined with the amount of planned and unplanned work that must be done to keep them running, are the chief barriers to achieving these outcomes.


Chapter 15 – Start where you are

The biggest barrier to success in changing the way you work is a conviction that your organization is too big or bureaucratic to change, or that your special context prevents adopting the particular practices we discuss. Always remember that each person, team, and business that started this journey was unsure of what paths to take and how it would end. The only accepted truth was that if they failed to take action, a more certain, negative ending lay ahead.

The only path to a culture of continuous improvement is to create an environment where learning new skills and getting better at what we do is considered valuable in its own right and is supported by management and leadership, thus reducing learning anxiety. We can use the Improvement kata (presented in chapter 6) to create this culture and drive continuous improvement.

The process of creating alignment and consensus between levels is critical. In strategy deployment, this process is described as catchball, a word chosen to evoke a collaborative exercise. The target conditions from one level should not be transcribed directly into the direction for teams working at the level below. Catchball is more about translation of strategy, with “each layer interpreting and translating what objectives from the level above mean for it”.

Using catchball to drive strategic alignment of objectives and initiatives

Begin your journey: use the following principles for getting started:

  • Ensure you have a clearly defined direction
  • Define and limit your initial scope
  • Pursue a high-performance culture of continuous improvement
  • Start with the right people
  • Find a way to deliver valuable, measurable results from early on

Creating a resilient, lean enterprise that can adapt rapidly to changing conditions relies on a culture of learning through experimentation. For this culture to thrive, the whole organization must be aware of its purpose and work continuously to understand the current conditions, set short-term target conditions, and enable people to experiment to achieve them.

We then reassess our current conditions, update our target conditions based on what we learned, and keep going. This behavior must become habitual and pervasive. That is how we create a mindset of continuous improvement focused on ever higher levels of customer service and quality at ever lower costs.
