Assess each team and categorize them into one of the four topologies, aligning them with the overall value stream and creating clear purpose and goals. Organizing teams according to these topologies allows organizations to manage dependencies, enhance collaboration, and facilitate effective value delivery. The four team topologies are: + Stream-aligned teams are responsible for delivering value to customers by focusing on specific product lines or customer segments. These teams possess cross-functional expertise that enables them to build, test, and deploy software independently, while minimizing dependencies and handoffs with other teams. They are the primary teams within the organization, normally representing 60–80% of the total teams within an organization. + Platform teams create and maintain shared infrastructure, tools, and services that support multiple stream-aligned teams across the organization. They produce reusable components, improve efficiency, reduce duplication of work, and overall reduce the amount of individual team effort. As these teams support many teams within the organization, they make up a smaller portion of the organization, usually between 10-20%. + Teams support other teams by providing just-in-time skills, knowledge, and expertise. They help other teams overcome technical challenges, adopt best practices, and improve their capabilities. All assistance provided by enabling teams is meant to be temporary, as they strive to make other teams self-sufficient through facilitation and mentoring. The percentage of enabling teams is fewer than platform and stream-aligned, often ranging between 5-15% of the overall organization. + Complicated subsystem teams are teams responsible for specialized subsystems within a larger system that require complex, deep domain knowledge and expertise. These subsystems are typically part of the core business logic or functionality of a single product or application. Their primary consumers are internal components within that system. Distinguishing between platform teams and complicated subsystem teams may not always be clear-cut, and a team could have characteristics of both types. When a team is providing a foundational service to multiple teams, they are usually considered platform teams. If they support a single product or application, it is generally considered a complicated subsystem team. Typically, there are fewer complicated subsystem teams than other team types, making up 0–10% of the distribution. **Related information:** + [Team Topologies](https://teamtopologies.com) # [OA.STD.2] Tailor operating models to business needs and team preferences **Category:** FOUNDATIONAL Adopt operating models that align with the needs of the business goals, while considering the capabilities and preferences of individual teams. The AWS Well-Architected Framework Operational Excellence Pillar provides a detailed [2 by 2 representations of operating model implementations](https://docs.aws.amazon.com/wellarchitected/latest/operational-excellence-pillar/operating-model-2-by-2-representations.html) that can be reviewed to gain insights into potential combinations. Selecting the right operating model involves evaluating the organization's requirements, such as decision-making processes, communication channels, and resource allocation. Keep in mind that multiple operating models can be used concurrently, catering to different use cases, levels of organizational maturity, and individual team and product needs. Not all operating models support a DevOps culture, and DevOps might not be suitable for every system. In some cases, especially in large and diverse organizations, it might be necessary to support stringent compliance requirements. Additionally, mass migration to a new way of working for all teams may not be feasible due to time, complexity of the system, or skill requirements. For these use cases, a [fully separated](https://docs.aws.amazon.com/wellarchitected/latest/operational-excellence-pillar/fully-separated-operating-model.html) operating model or introducing an Internal MSP and Consulting Partner might be needed for those systems that must stay *as is* with more traditional ways of working. When choosing a Well-Architected operating model for systems that can support DevOps, first determine if centralized or decentralized control of governance is necessary. A centralized governance model grants platform teams within an organization the ability to control *how* and *what* other teams are able to deploy, at the cost of restricting those teams' ability to innovate and make changes quickly. Conversely, a fully decentralized model offers teams more flexibility and autonomy, requiring less intensive collaboration between teams through reliance on guardrails and automated governance over strict control. **Related information:** + [AWS Well-Architected Operational Excellence Pillar: Operating model 2 by 2 representations](https://docs.aws.amazon.com/wellarchitected/latest/operational-excellence-pillar/operating-model-2-by-2-representations.html) + [Building your Cloud Operating Model: Organize for Success](https://docs.aws.amazon.com/prescriptive-guidance/latest/strategy-cloud-operating-model/implement-roadmap.html#organize) # [OA.STD.3] Prioritize shared accountability over individual achievements **Category:** FOUNDATIONAL Encourage a culture of teamwork and shared accountability by establishing common goals and fostering collaboration and open communication. Create a sense of shared ownership and responsibility for achieving team success, encouraging members to support each other and provide constructive feedback. Regularly evaluate progress towards goals and celebrate successes together as a team. Prioritizing team success over individual accomplishments promotes a cohesive and high-performing team environment that is essential for successful DevOps adoption. # [OA.STD.4] Structure teams around desired business outcomes **Category:** FOUNDATIONAL To maximize value and effectiveness in product delivery, intentionally design team structures that reflect the desired architecture and interactions of the systems being built. Clearly define roles, responsibilities, and ownership for each team and align with the expected business outcomes. This approach increases the chances of building and supporting effective products optimized for full coverage of the full value stream. Conway's Law, introduced by Melvin Conway in the paper [https://www.melconway.com/Home/pdf/committees.pdf](https://www.melconway.com/Home/pdf/committees.pdf), posits that the structure of an organization influences the design of the systems it builds. Organizations can use this concept to build more effective team structures by employing the [Inverse Conway Maneuver](http://jonnyleroy.com/2011/02/03/dealing-with-creaky-legacy-platforms/), also known as *Reverse Conway's Law*, as described by Jonny LeRoy and Matt Simons. By designing teams and their communication structures to reflect the intended architecture and interactions of the system being built, organizations can achieve increased efficiency and more effective collaboration between teams, ultimately enhancing the overall product delivery process. **Related information:** + [How Do Committees Invent?](https://www.melconway.com/Home/pdf/committees.pdf) + [Dealing with creaky legacy platforms](http://jonnyleroy.com/2011/02/03/dealing-with-creaky-legacy-platforms/) + [Demystifying Conway's Law](https://www.thoughtworks.com/insights/articles/demystifying-conways-law) + [Inverse Conway Maneuver](https://www.thoughtworks.com/en-de/radar/techniques/inverse-conway-maneuver) # [OA.STD.5] Establish team norms that enhance work performance **Category:** FOUNDATIONAL Optimize work performance by establishing norms that define clear roles, schedules, and processes for agile ceremonies. Agree on regular meeting schedules, such as daily stand-ups, sprint planning, backlog refinement, and sprint retrospectives if you are following Scrum. Define roles for each team member during ceremonies, clarifying responsibilities and purpose in the ceremony. Conduct regular process reviews to identify areas for improvement and refine the ceremony structure as needed. Encourage active participation and engagement in the ceremonies. When establishing team norms, consider the stages of group development as described in the paper [Developmental Sequence in Small Groups](https://psycnet.apa.org/record/1965-12187-001) by Bruce Tuckman, which describes the common stages of forming, storming, norming, and performing. Be mindful of these stages to provide the right support to teams, especially as they progress through the early phases of group formation. **Related information:** + [What Is Scrum?](https://aws.amazon.com/what-is/scrum) + [Developmental sequence in small groups](https://psycnet.apa.org/record/1965-12187-001) # [OA.STD.6] Provide teams ownership of the entire value stream for their product **Category:** FOUNDATIONAL Establish teams that are able to own their respective value streams and products. These teams follow a *you build it, you run it* approach, as coined by Werner Vogels in 2006. The team responsible for building a system should also be responsible for running, maintaining, and overall owning it. At Amazon, we call these small, autonomous teams with a single-threaded focus [two-pizza teams](https://docs.aws.amazon.com/whitepapers/latest/introduction-devops-aws/two-pizza-teams.html). This approach minimizes handoffs and makes teams both the creators and custodians of their products. Value stream ownership does not mean preventing teams from working together. These teams not only own the development of their product, but also take responsibility of aspects like security and quality assurance. To be successful in this model at scale, centralized functions, such as centralized security teams, must also evolve: instead of direct oversight, they should act as enablers, providing resources and expertise to these distributed teams. The enabling functions should provide the necessary knowledge, resources, and attention required for teams to be successful. Individual teams build relationships with the centralized functions, share knowledge, and enhance processes consistently over time. This ultimately leads to improved outcomes for their products, customers, and the organization. Invest in ongoing cross-functional training to help individual team members acquire skills that will make them successful within their value streams. This training could include teaching developers to be security-minded, or teaching security resources to develop. Over time the teams should gradually become more self-reliant, collaboration between teams should improve, and deployment frequency should increase. **Related information:** + [AWS Well-Architected Security Pillar: SEC11-BP01 Train for application security](https://docs.aws.amazon.com/wellarchitected/latest/framework/sec_appsec_train_for_application_security.html) + [AWS Well-Architected Security Pillar: SEC11-BP08 Build a program that embeds security ownership in workload teams](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/sec_appsec_build_program_that_embeds_security_ownership_in_teams.html) + [Enterprise DevOps: Why You Should Run What You Build](https://aws.amazon.com/blogs/enterprise-strategy/enterprise-devops-why-you-should-run-what-you-build/) + [Amazon's approach to security during development: Ownership](https://youtu.be/NeR7FhHqDGQ?t=632) + [Amazon's approach to security during development: Security Review Process](https://youtu.be/NeR7FhHqDGQ?t=1285) + [Powering Innovation and Speed with Amazon's Two-Pizza Teams](https://aws.amazon.com/executive-insights/content/amazon-two-pizza-team/) + [The Amazon Software Development Process: DevOps Teams](https://youtu.be/52SC80SFPOw?t=387) # [OA.STD.7] Amplify the scale and impact of centralized functions **Category:** FOUNDATIONAL As decentralized teams become responsible for their respective value streams and products, including responsibilities like security and quality assurance, centralized functions can often become bottlenecks. These bottlenecks can delay releases and cause inefficiencies in the development lifecycle, which can limit the adoption of DevOps best practices. We recommend adopting a [Guardian Model](https://www.youtube.com/clip/UgkxFAoUn6nHH6D3GjwAHD3xXK07Q2NhcYGx) within your organization to scale centralized functions. This involves embedding specialized champions or *Guardians* within individual teams to enhance and scale the capabilities of centralized functions, such as security, quality, and audit. Embedding guardians directly into teams helps make specialized knowledge always available, reducing wait times and facilitating real-time, context-aware decision-making. This approach not only accelerates delivery, but also continually meets quality, security, and compliance standards. To implement this model, begin by defining the strategy for the initiative. Recognize the inefficiencies and gaps within teams that these guardians can rectify, and identify which centralized function would benefit most from on-the-ground, embedded expertise. Security, quality assurance, and audit functions are great examples of centralized functions that must scale when adopting DevOps best practices. Leadership support is required so that they can allocate necessary resources, make policy changes, and inspire an organizational culture that genuinely values the guardian role. When selecting and training guardians, pinpoint passionate team members who volunteer to undergo specialized training to become focal points for their respective domains. This includes proactive responsibilities, such as threat modeling or test planning, and reactive responsibilities, like defect resolution or compliance checks. These responsibilities should be clearly defined to avoid ambiguity, confusion, and conflict. Continue to gather feedback from guardians and their teams, using the insights to refine and iterate on the model. The guardian role is an important factor for the success of this model. Encourage adoption of the role by providing specialized training opportunities, avenues for influencing best practices, and clear paths for career evolution. These incentives keep guardians motivated, engaged, and eager to drive excellence within their respective teams. **Related information:** + [AWS Well-Architected Security Pillar: SEC11-BP08 Build a program that embeds security ownership in workload teams](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/sec_appsec_build_program_that_embeds_security_ownership_in_teams.html) + [Scaling security and compliance](https://aws.amazon.com/blogs/security/scaling-security-and-compliance/) + [AWS Security Guardians](https://youtube.com/clip/UgkxFAoUn6nHH6D3GjwAHD3xXK07Q2NhcYGx) + [Amazon's approach to security during development: Security Review Process](https://youtu.be/NeR7FhHqDGQ?t=1285) # [OA.STD.8] Promote cognitive diversity within teams [OA.STD.8] Promote cognitive diversity within teams **Category:** RECOMMENDED Optimized DevOps teams should remain small and agile in how they deliver their products. This approach requires team members to have a wide range of cross-functional skills, from software development and testing to operations and security. Having a diverse mix of skills, experiences, and backgrounds within the team helps them effectively innovate to solve complex problems and better mimic the personas and culture of their users. Promote cognitive diversity within small teams by including members with varied ethnic, cultural, regional, gender, age, and other backgrounds. Avoid hiring bias and promote diversity and inclusion when forming teams. Implement inclusive hiring practices, such as blind resume screening and diverse interview panels. Encourage cross-functional collaboration and knowledge sharing so that teams can frequently gain the perspectives of others. Aim to maintain strong cognitive diversity by regularly assessing the diversity of the team and identifying any potential gaps. This can be done through team surveys, diversity and inclusion training, and ongoing monitoring and evaluation. Additionally, invest in security training and awareness programs, equipping your team members with the knowledge and skills to identify and mitigate security risks. Doing so enhances the overall security posture and culture of the organization. By creating teams that embrace cognitive diversity, organizations can improve innovation, creativity, and problem solving, leading to better outcomes for the organization and its customers. **Related information:** + [AWS Well-Architected Security Pillar: SEC11-BP01 Train for application security](https://docs.aws.amazon.com/wellarchitected/latest/framework/sec_appsec_train_for_application_security.html)
