Delivery process
Simple enough to scan. Strong enough to trust.
Clients should understand how the work moves before they ever send the first message.
Diagnose
Identify the exact workbook, export, or reporting loop that is creating decision friction.
Stabilize
Fix structure first: invalid fields, duplicates, broken formulas, and inconsistent naming.
Build
Create the workbook, reporting layer, or automation logic with stakeholder-readable formatting.
Hand off
Deliver stable files, notes, and a next-step path for future edits or owner transfer.
