Business Transformation Assumptions Log
This is a practical guide to building a assumptions log for a business transformation project — a register of the assumptions the plan depends on, to be validated, adapted to the realities of reshaping how a business operates end to end.
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 business transformation project it plays the same role, tuned to this kind of work.
Why it matters for a Business Transformation project
Business Transformation projects live or die on reshaping how a business operates end to end. 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 business transformation projects drift into avoidable delay and cost.
What to include
- Assumption
- Impact if wrong
- Owner
- Validation status
Business Transformation-specific considerations
Tailor the assumptions log to the risks that most often derail business transformation projects:
- Change fatigue
- Scope too broad to control
- Benefits not tracked
Example
On a real business transformation project, the assumptions log would be shaped by reshaping how a business operates end to end. In particular, it should explicitly account for the project’s biggest risks — change fatigue, scope too broad to control, benefits not tracked — rather than treating them as afterthoughts.
