The assumption behind the proposal.

For a pricing proposal, the question may be how much volume could change before the expected contribution is lost. For an activity under review, it may be whether withdrawing would release the capital the group expects.

We agree the proposal, the alternatives worth examining and the work required. The written scope covers deliverables, timing, fees and access to information.

Read the relevant terms before assuming that revenue or cost can change. A customer may have a fixed renewal date; a supplier may require a minimum purchase; capacity may already be committed. Those conditions enter the assessment beside the forecast.

Trading and operating records help establish the present position. Where the proposed customer response has not occurred, it remains an assumption to examine rather than a result established by the existing figures.

Change the commercial assumption and follow its effect through the proposal. A lower quantity can affect contribution, stock and spare capacity differently. A smaller opening commitment can alter what the business is able to offer.

The comparison identifies the conditions under which an option remains workable and the commitments it leaves behind. Its level of detail follows the pricing, portfolio, investment or transaction question in the brief.

The conclusion explains which commercial conditions support the proposal and what would change the assessment. A finding may support the current terms, identify an alternative or leave a particular assumption unresolved.

The people using the work can examine those conditions before deciding how to proceed. Further analysis or implementation support is included only where agreed; specialist conclusions remain with the professionals responsible for them.
