Scrum has no separate architect accountability. An architect who works within a Scrum Team contributes as one of its Developers, helping the team make sound technical decisions and deliver a valuable, usable Increment. An architect supporting several teams can coordinate shared technical concerns, but does not become a fourth Scrum accountability or an approval gate above the teams.
Is an architect part of a Scrum Team?
It depends on how the architect works. If the architect is a member of the team doing product work, that person participates as a Developer. Scrum uses “Developers” for the professionals who create any part of a usable Increment; it is not a job title limited to programmers. The architect shares responsibility with the team for creating a valuable Increment.
If an architect advises multiple teams without being a member of one, that is a specialist or enabling function outside Scrum’s formal accountabilities. The person may still be important to delivery, especially where teams share platforms or system boundaries, but Scrum does not define an architect as a distinct role.
What Scrum says about architecture and team structure
The Scrum Guide, by Ken Schwaber and Jeff Sutherland, defines one cohesive, cross-functional, self-managing Scrum Team with three accountabilities: Product Owner, Scrum Master, and Developers. Scrum.org’s Scrum Team guidance puts the structural implication plainly: “Within a Scrum Team, there are no sub-teams or hierarchies.” An architect therefore is not a fourth accountability, a superior tier, or a separate design group inside the team.
#1 Best Overall
The team is responsible for all product-related activities needed to create a valuable, useful Increment, including research, development, maintenance, operation, and verification. The 2020 Scrum Guide update consolidated the former Development Team into a single Scrum Team and retained only the three accountabilities above. Architecture work belongs in that shared delivery effort when it helps the product.
What an architect does day to day on a Scrum Team
Connect technical choices to the product goal
Help the team understand the constraints and options behind a decision: for example, how an interface, data model, deployment approach, or security requirement affects the product. Describe trade-offs and risks in terms the team and relevant stakeholders can act on, rather than presenting a design as a finished instruction set detached from delivery.
Rank #2
Contribute to building the Increment
Architecture is part of product work, not a phase that must be completed before Developers can begin. An architect can contribute through code, prototypes, tests, interface design, deployment design, and other concrete work that helps produce a usable Increment. Pairing with another Developer or validating a risky assumption with a small prototype can both improve the design and keep the knowledge shared.
Make architecture work visible
When technical work is needed to meet the Product Goal or Sprint Goal, make it visible in the Product Backlog or Sprint Backlog. A team might use a spike, technical story, refactoring work, enabler, or acceptance criterion; Scrum prescribes no particular item type. The important point is that the work is understood and prioritized alongside other work, not hidden in a separate architectural queue that can never be inspected.
Rank #3
Help the team make quality explicit
Work with the team to express relevant non-functional requirements—such as security, operability, performance, and maintainability—in acceptance criteria and the Definition of Done. These checks should reflect what is needed for a usable Increment. An architect can help identify risks and clarify how to verify them, while the team retains shared responsibility for meeting its quality commitments.
Spread architectural understanding
Pair with Developers, review designs and code collaboratively, explain constraints, and document decisions and consequences in a lightweight way. The aim is to grow the team’s ability to make and revisit technical choices, not to make the architect the only person who understands the system.
Who makes architecture decisions in Scrum?
The Scrum Guide does not assign technical decisions to a separate architect. A self-managing team decides who does what, when, and how. In practice, the people closest to the work should be involved in choices that shape it; an architect can frame alternatives, surface risks, and facilitate a decision, but should not turn every technical choice into an external approval request.
For decisions with broader consequences, involve the affected teams and stakeholders. Record the decision and its rationale or consequences where future contributors can find them. Keep the record proportionate: useful enough to preserve context, without making documentation a substitute for discussion or working software.

There is no single arrangement that fits every product. The choice depends on system size, coupling, regulatory constraints, and how many teams share a platform. An embedded architect supports quick local feedback and keeps understanding close to implementation. A shared architecture function can help align interfaces, security expectations, standards, and platform investments across teams, but adds coordination overhead.
| Arrangement | Decision latency | Local ownership | Cross-team consistency | Runway investment |
|---|---|---|---|---|
| Architect embedded in a Scrum Team | Typically supports faster local feedback and implementation. | High when the architect pairs and shares knowledge with the team. | May need deliberate coordination where systems or platforms are shared. | Can shape technical foundations alongside near-term product work. |
| Shared or enterprise architecture function | Can increase latency if routine decisions require central approval. | Can weaken if implementation knowledge is concentrated outside delivery teams. | Can improve alignment on shared interfaces, security, and platform constraints. | Can coordinate investment in foundations used by multiple teams. |
Scaled Agile describes architectural runway as existing code, components, and technical infrastructure needed to implement near-term features with minimal redesign and delay. Its guidance recognizes a balance between emergent design and intentional architecture, with centralized planning and cross-team coordination where needed. In Scrum settings, that coordination is most useful when it enables teams to deliver; it should not displace their day-to-day implementation decisions.
Quick Recap
What an architect should not become
- A fourth Scrum accountability: Scrum defines Product Owner, Scrum Master, and Developers.
- A hierarchy above Developers: the Scrum Team has no sub-teams or internal hierarchy.
- A universal approval gate: routing every technical decision through one person can slow delivery and undermine self-management.
- A substitute for team capability: the team still needs the skills and collaboration to create a usable Increment, rather than depending on a single architect to complete or approve the design.
