Decentralizing Architectural Decisions with the Architecture Advice Process
Why Traditional Architecture Roles Fail in Modern Teams
Modern software systems have evolved dramatically, but many organizations still cling to outdated architectural practices. The traditional “ivory tower” architect role—where a single expert dictates all decisions—creates bottlenecks and stifles innovation. As Andrew Harmel-Law explains, this approach can’t scale in today’s fast-paced, distributed development environments.
The Bottleneck Problem
When only a few individuals are responsible for architectural decisions, they become flow blockers. They must:
- Understand all system contexts
- Anticipate future requirements
- Account for implementation feedback
This is unsustainable. As Harmel-Law notes, “No one can be in all the right places at the right times.” The result? Delayed decisions, frustrated teams, and architectures that don’t reflect real-world usage.
Introducing the Architecture Advice Process
The Architecture Advice Process (AAP) flips this model. Instead of centralized control, it empowers teams to make decisions while ensuring expertise is leveraged. The core principle: “Anyone can make any decision, as long as they seek advice from affected parties and experts.”
How the Advice Process Works
The AAP operates on three key principles:
- Responsibility Transfer: Decision-making authority shifts to those who need it
- Expert Involvement: Advice is sought from stakeholders and specialists
- Accountability: Decision-makers own the outcomes
This creates a feedback-rich environment where architecture emerges from practical conversations rather than top-down mandates.
Case Study: Platform Selection
Consider a team choosing between:
- Lambda functions
- Kubernetes microservices
- Bespoke compute nodes
Using AAP, the team would:
- Engage systems architects for technical feasibility
- Consult operations teams on deployment needs
- Involve security experts for compliance checks
The final decision emerges from this collaborative process, not from a single authority.
Common Failure Patterns to Avoid
While AAP offers significant benefits, certain pitfalls can undermine its effectiveness:
1. Senior Overreach
When experienced leaders override decisions made by teams, they defeat the purpose of decentralization. AAP requires trust in the process and the people executing it.
2. The “Old Guard” Problem
If the same senior architects continue making all decisions, AAP fails to deliver its promised empowerment. The goal is to distribute expertise, not shift power.
3. Unrecorded Decisions
Decisions made in private conversations without documentation create knowledge silos. AAP requires transparency through mechanisms like Architecture Decision Records (ADRs).
4. Lack of Trust
Teams must believe in each other’s ability to make sound decisions. Without trust, the process becomes a rubber-stamping exercise.
Adopting the Architecture Advice Process
Transitioning to AAP requires cultural change:
- Train teams to evaluate architectural trade-offs
- Establish clear channels for seeking advice
- Document decisions using ADRs
- Measure outcomes, not just compliance
As Harmel-Law emphasizes, “This isn’t about following a checklist—it’s about fostering the right conversations at the right time.” The process will evolve uniquely for each organization, shaped by its context and needs.
Conclusion: Embracing Decentralized Architecture
The Architecture Advice Process represents a paradigm shift in how we approach software design. By decentralizing decisions, we:
- Accelerate development cycles
- Reduce bottlenecks
- Empower teams
- Improve knowledge sharing

FAQs
What is the Architecture Advice Process?
The Architecture Advice Process (AAP) is a decentralized decision-making framework where teams make architectural choices after seeking expert advice, rather than relying on centralized authorities.
How does AAP reduce bottlenecks?
By distributing decision-making authority, AAP eliminates single points of failure and accelerates the flow of work through collaborative problem-solving.
What are Architecture Decision Records (ADRs)?
ADRs are documentation templates that capture the context, decision, and consequences of architectural choices, ensuring transparency and knowledge sharing.
Can AAP work in regulated industries?
Yes, AAP can be adapted to regulatory environments by incorporating compliance checks into the advice-giving process while maintaining decentralized decision-making.
How to handle disagreements in AAP?
Disagreements are resolved through evidence-based discussions rather than authority. The decision-maker evaluates all advice and chooses the best path forward.
