Mobile App Development Decision Log
This is a practical guide to building a decision log for a mobile app development project — a record of the key decisions made, by whom and why, adapted to the realities of building a native or cross-platform mobile app.
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 mobile app development project it plays the same role, tuned to this kind of work.
Why it matters for a Mobile App Development project
Mobile App Development projects live or die on building a native or cross-platform mobile app. 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 mobile app development projects drift into avoidable delay and cost.
What to include
- Decision
- Date and owner
- Rationale
- Alternatives considered
- Impact
Mobile App Development-specific considerations
Tailor the decision log to the risks that most often derail mobile app development projects:
- App-store approval delays
- Device fragmentation
- Evolving feature scope
Example
On a real mobile app development project, the decision log would be shaped by building a native or cross-platform mobile app. In particular, it should explicitly account for the project’s biggest risks — app-store approval delays, device fragmentation, evolving feature scope — rather than treating them as afterthoughts.
