Digital Project Estimation Guide

A structured approach to estimating digital implementation projects, grounded in discovery findings rather than assumptions.

Contents

What this covers

Architecture Complexity

How system count and type affects complexity
Scoring architecture complexity from discovery
Common high-complexity architecture patterns
Using complexity scores to anchor estimates

Integration Complexity

Why integrations are the primary source of scope risk
Scoring integration complexity by type and volume
Integration complexity multipliers
How integration risk compounds across projects

Data Modeling Complexity

How data model maturity affects implementation effort
Scoring data migration and transformation complexity
Data model gaps as scope risk indicators
When data modeling work should be in scope

Team Composition

How architecture complexity maps to team structure
Common team configurations for commerce implementations
When specialist roles are required
Team composition communication in proposals

Timeline Estimation

How to build timeline ranges from complexity scores
Milestone sequencing from discovery findings
Risk buffers and contingency planning
Communicating timeline ranges with confidence

“ERP + PIM + Commerce implementations typically require 18–24 weeks. This guide explains why, and how to make that visible from discovery.”
