Office Add-in Project Planning: Budget, ROI, and Delivery Timelines

Categorizing add-ins by complexity

Understanding the Investment Landscape

Development costs are primarily driven by the 'Integration Layer'—how many external systems (SAP, Salesforce, Private DBs) the add-in must communicate with.

Expert Insight

Start with an MVP focusing on one single application (e.g., Outlook) before expanding the codebase to Excel or Word to validate user adoption first.

Summary

Proper scoping of Graph permissions and UI requirements early can save up to 30% of the total project budget.
