Imagine you are comparing two proposals for fractional technical leadership. Your product is running, your engineering team is working, and a customer has asked for an integration that could affect the next release.
The first proposal offers strategic direction and a meeting every other week. The second includes a weekly discussion with the engineering lead and time to review decisions within an agreed schedule. Both sound useful. Their fees are different.
Before choosing, you need to know what will happen when your team has to decide whether to accept the integration, change its scope, or move another commitment. Who will investigate the options? Who can make the recommendation? Who has authority to change the plan? And who will keep the work moving after the meeting?
The proposals may answer those questions in different ways. A lower fee may be reasonable if the work outside the proposal is already covered. It may also leave an important responsibility with someone who has no time or authority to take it on.
