The problem
Project delivery, acceptance, billing, and payment evidence often live in separate spreadsheets owned by different teams. That makes it difficult to see whether work is on plan, which claims are blocked, and how a revised schedule affects expected cash flow.
The approach
The project defines a governed control center around a normalized operating model. Google Sheets acts as the system of record, Forms standardize updates, Apps Script handles validation and workflow automation, and a reporting layer turns the reviewed data into decision-ready views.
The design keeps planned and actual events separate, records every approved revision, and links each operational update back to a stable project and installment reference.
What it explores
- Converting spreadsheet-shaped processes into structured operational data
- Plan-versus-Actual and cumulative progress reporting
- Revision history, validation, and accountable ownership
- Delivery, acceptance, invoice, and payment milestone tracking
- Executive, project-management, and finance views from one data model
Public boundary
This case study describes the method using generalized language and sample structures. Organization names, contract values, project identifiers, documents, and operational records are intentionally excluded.
The current deliverable is an implementation-ready data model and workspace scaffold, not a claim that the full organizational workflow is already in production.
