“In Enterprise Architecture, it’s crucial to capture architectural decisions, along with the trade-offs made within the context and constraints at a given point in time. In software engineering and software architecture design, architectural decisions are design decisions that address architecturally significant requirements; they are perceived as hard to make and/or costly to change. This enables you to use pull requests for ADR reviews, so the team can discuss and approve architectural decisions just like code changes. As systems grow more complex and teams become more distributed, architectural decisions become harder to make, and even harder to stick to. Consider areas such as specific people, or specific roles, or specific teams, or specific departments; also consider if there are people, or roles, or teams, or department that can commission an ADR, meaning they request one that someone else will author. Claude can help you think through options systematically, surface trade-offs you hadn’t considered, stress-test your assumptions, and document the reasoning so your future self (and teammates) understand why a decision was made.
In this he was particularly inspired by Phillipe Kruchten talking about decision registers / decision logs, and by the writing style of software patterns. Keep the ADR http://spacehike.com/flightmech.html short and to the point – typically a single page. ADRs play a central role in the Advice Process, where they are not only used to document decisions, but the act of writing them is used to elicit expertise and alignment.
Inputs Real source material, audience, constraints, and success criteria Some organizations aim for radical team autonomy, and some aim for high consistency and alignment, which are more restrictive. Sometimes you may have an engineer who solved similar challenges in the past but is not directly working on them right now. While it’s common to involve everyone affected in the ADR review, sharing it with more people increases overall architectural awareness across https://www.softcourier.com/68418/details-code-to-flowchart-converter.html an organization. The ADR review process can be used for multiple purposes—reviewing and approving decisions and sharing knowledge. They also help new team members get up to speed on the overall architecture and reasons behind significant decisions.
A Simple Framework for Architectural Decisions
As with most written documents, writing ADRs serves two purposes. They should not be modified if the decision is changed, but linked to a superseding decision. Documents should be short, just a couple of pages, and contain the decision, the context for making it, and significant ramifications. An Architecture Decision Record (ADR) is a short document that captures and explains a single decision relevant to a product or ecosystem.
Identify a real architectural decision you’re facing or have recently made. Where will this break down as requirements change? Instead, ask for https://www.softarmy.com/24113/download-text-file-workshop.html an honest analysis of each option against your criteria. With criteria, they become structured trade-off analyses. Without explicit criteria, architectural evaluations become debates about preferences. This is exactly the kind of structured reasoning under uncertainty where Claude adds the most value.
