Network Upgrade Assumptions Log
This is a practical guide to building a assumptions log for a network upgrade project — a register of the assumptions the plan depends on, to be validated, adapted to the realities of upgrading network infrastructure and connectivity.
What a Assumptions Log is
A assumptions log is a register of the assumptions the plan depends on, to be validated. For the full concept and how it works in general, see Project Assumption. 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 assumptions 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
- Assumption
- Impact if wrong
- Owner
- Validation status
Network Upgrade-specific considerations
Tailor the assumptions 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 assumptions 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.
