Network Upgrade Decision Log
This is a practical guide to building a decision log for a network upgrade project — a record of the key decisions made, by whom and why, adapted to the realities of upgrading network infrastructure and connectivity.
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 network upgrade project it plays the same role, tuned to this kind of work.
Why it matters for a Network Upgrade project
Network Upgrade projects live or die on upgrading network infrastructure and connectivity. 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 network upgrade projects drift into avoidable delay and cost.
What to include
- Decision
- Date and owner
- Rationale
- Alternatives considered
- Impact
Network Upgrade-specific considerations
Tailor the decision log to the risks that most often derail network upgrade projects:
- Downtime during cutover
- Hardware lead times
- Legacy compatibility
Example
On a real network upgrade project, the decision log would be shaped by upgrading network infrastructure and connectivity. In particular, it should explicitly account for the project’s biggest risks — downtime during cutover, hardware lead times, legacy compatibility — rather than treating them as afterthoughts.
