Code with Context: Documenting Decisions That Matter
In software development, decisions are everywhere, from choosing a framework to defining how services interact. These decisions shape the architecture of a system, influencing its performance, scalability, security, and maintainability. Yet, in the rush to build and ship, many of these critical choices are made informally, discussed in meetings, or buried in chat threads, only to be forgotten or misunderstood later.
Imagine joining a project and wondering why a certain technology was chosen, why a service was split, or why a particular pattern was used. Without clear documentation, you're left to guess, reverse-engineer intent, or repeat past mistakes.
This is where Architecture Decision Records (ADRs) come in. ADRs offer a simple, structured way to capture the "why" behind architectural choices. They turn fleeting conversations into lasting knowledge, helping teams stay aligned, reduce confusion, and build systems with confidence.
What are ADRs?
In any software project, whether you're building a web app, integrating APIs, or customizing a CRM, architectural decisions are the invisible threads that hold the system together. These decisions define how components interact, how data flows, and how the system scales and evolves.
Architecture Decision Records (ADRs) are simple, structured documents that capture the reasoning behind these decisions. They help teams answer questions like:
ADRs are especially valuable in Salesforce projects, where decisions often involve choosing between declarative tools (like Flows or Process Builder) and programmatic solutions (like Apex or Lightning Web Components), or selecting the right integration method (REST API, Platform Events, External Services, etc.).
What’s Included in an ADR?
A well-crafted ADR typically includes:
1. Title
A short, descriptive name for the decision.
Example: ADR 007: Use Salesforce Flow for Lead Assignment Logic
2. Status
Indicates the lifecycle of the decision (e.g., Proposed, Accepted, Deprecated).
Example: Status: Accepted
3. Context
Explains the business or technical scenario that led to the decision.
Example: "We need to automate lead assignment based on region and product interest."
4. Decision
Clearly states what was chosen and why.

Example: "We will use Salesforce Flow to implement the logic due to its flexibility and ease of maintenance by admins."
5. Alternatives Considered
Lists other options and why they were not selected.
Example: "Apex triggers were considered but rejected due to increased complexity and reduced visibility for non-developers."
6. Consequences
Outlines the impact of the decision—positive and negative.
Example: "Improved maintainability and admin control, but limited support for complex branching logic."
7. Date & Authors
Optional but useful for tracking when and by whom the decision was made.
Conclusion
Architectural decisions are the silent drivers behind every successful software system. Whether you're working on a complex Salesforce implementation or a cloud-native application, the choices you make today will shape how your system performs, scales, and evolves tomorrow.
Architecture Decision Records (ADRs) provide a straightforward yet powerful means of capturing those choices with clarity and purpose. They transform fleeting conversations into lasting documentation, helping teams stay aligned, reduce rework, and build with confidence.
In the Salesforce ecosystem, where flexibility meets complexity, ADRs are especially valuable. They help bridge the gap between declarative and programmatic solutions, support collaboration across roles, and ensure that every decision is made with transparency and foresight.
By adopting ADRs, you're not just documenting decisions—you're investing in the long-term health and agility of your architecture.
