Web Application Development Decision Log
This is a practical guide to building a decision log for a web application development project — a record of the key decisions made, by whom and why, adapted to the realities of building a custom web application.
What a Decision Log is
A decision log is a record of the key decisions made, by whom and why. For the full concept and how it works in general, see Decision Log. On a web application development project it plays the same role, tuned to this kind of work.
Why it matters for a Web Application Development project
Web Application Development projects live or die on building a custom web application. A well-built decision log gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how web application development projects drift into avoidable delay and cost.
What to include
- Decision
- Date and owner
- Rationale
- Alternatives considered
- Impact
Web Application Development-specific considerations
Tailor the decision log to the risks that most often derail web application development projects:
- Unclear or shifting requirements
- Technical debt
- Security and performance at scale
Example
On a real web application development project, the decision log would be shaped by building a custom web application. In particular, it should explicitly account for the project’s biggest risks — unclear or shifting requirements, technical debt, security and performance at scale — rather than treating them as afterthoughts.
