Review Checklist
What reviewers usually validate first
These are the areas teams usually discuss first once the calculation or analysis is visible.
Confirm the revenue figure used as the denominator matches the period being analyzed.
Check whether the cost of goods sold share is consistent with prior periods and industry norms.
Verify that selling, general, and administrative costs are not growing faster than revenue.
Assess whether the gross margin percentage supports the operating model and growth targets.
Evaluate whether operating income as a percentage of revenue meets management expectations.
Compare the bottom-line share against prior periods and peer companies for consistency.
