Business Impact
3

Moderate impact. Meaningful cost or revenue improvement, likely noticeable at function level but modest relative to total business scale.

Feasibility
3

Moderate effort. Requires configuration, prompt engineering, and testing. A capable team can get there but expect several months.

Data Readiness
2

Demanding data requirements. Relies on clean, integrated data across multiple systems. Significant data preparation work typically needed.

Risk Exposure
4

Low risk. Limited external exposure. A human reviews output before it reaches anyone outside the team.

Change Complexity
3

Moderate people impact. Part of someone's working day changes. Requires training and some adjustment time, but roles remain broadly the same.

Things to consider

  • Cost increase requests arrive faster than buyers can analyse them, so the default answer becomes partial acceptance. Even a rough evidence pack shifts that default.

  • You need the bill of materials to link a supplier's claimed input inflation to a published index. Without it the analysis is a general argument about inflation, which suppliers win.

  • Do not let the analysis run the relationship. A supplier squeezed on evidence alone will find the recovery elsewhere — in service, in spec, or in the next negotiation.

  • Experiment starter: Take the last twenty cost increase requests you accepted. Rebuild the evidence position for each and quantify the gap between what was accepted and what the evidence supported. That gap, annualised, is the case.
