How do you build a business case for a change?
From the model rather than beside it. The cost, effort and expected return are attached to the processes the change touches, so every figure can be traced to what produced it. Change the design and the case moves with it, instead of being a spreadsheet that was true on the day it was written.
How business case and roi works in Omni
Assumptions on the record
A modelled number shows what it was modelled from. Anyone reviewing the case can see the assumption and argue with it, which is the point.
The case updates with the design
Scope changes are normal. When the design moves, the case moves, so approval is not given against a version nobody is building.
One case finance and delivery share
The same figures serve the funding conversation and the delivery plan, so there is nothing to reconcile between them later.
What you get
- A case a reviewer can interrogate instead of taking on trust
- Numbers that survive the scope changing
- One set of figures across finance, architecture and delivery
Common questions
Do you produce the numbers, or do we?
You do, and Omni shows its working. A modelled figure always displays the assumptions behind it. Omni never presents a number it was not given or cannot derive.
