Consulting engagement estimating: discovery to handoff

Define the decision and the deliverable

State the question to answer, the available evidence, the intended audience and the final output. A strategy recommendation based on six interviews and supplied sales data is different from implementing the recommendation. Name the implementation, training and follow-up work that is excluded. Use the proposal checklist to make those boundaries reviewable.

Count the work around the visible meeting

Suppose six interviews require two hours each including preparation and notes: 12 hours. Add 30 hours of analysis, 20 of synthesis, 12 of review and revision, and six of handoff. Total effort is 80 hours. At an illustrative loaded cost of 100 per hour, labor cost is 8,000. Another 2,000 of direct expenses and allocated overhead creates a 10,000 cost basis. A 25% gross margin requires about 13,333.33 revenue.

Those are deterministic example numbers. If data cleanup or stakeholder availability is uncertain, give the affected tasks ranges and represent the waiting relationships. The advisory engagement template is an inspectable starting point, not a standard consulting benchmark.

Bound discovery when the evidence is missing

List what must be learned before committing to the larger scope: data access, stakeholder alignment, permissions, interfaces or acceptance criteria. Define a discovery deliverable and a point at which you revisit the implementation estimate. This does not make the later quote certain; it changes which assumptions have evidence. Read the cone of uncertainty for a worked discussion of estimate maturity.

Distinguish a deliverable review from a new assignment

Define the included review rounds, consolidation of feedback and decision owner. A new stakeholder question, a different data source or a new presentation audience may require more analysis. Cost that incremental work with the scope-change calculator. Record which original assumptions remain valid and which must be re-estimated.

Compare a practical mitigation

If a 30% chance of data rework would cost 12,000, expected risk cost is 3,600. An upfront validation costing 1,500 that reduces the event to a 10% chance of 8,000 leaves 800 expected residual cost. Net expected benefit is 1,300. Use the mitigation calculator to challenge that assumed reduction. The arithmetic cannot verify whether the validation actually has that effect.

Make the handoff useful

Deliver the recommendation with its evidence, assumptions, exclusions and unresolved decisions. Separate a confidence statement about the estimate from confidence in the business recommendation. A modeled 80% chance of staying within cost is not an 80% chance that the proposed strategy succeeds.
