This document describes a Deployment Excellence Framework (DEF) to effectively adopt high maturity processes. The framework includes 3 interlinked cycles: 1) Identification Cycle to target initial units and stakeholders, 2) Initial Deployment Cycle focusing on awareness and success indicators, and 3) Sustenance Cycle increasing adoption scope and self-reliance. It also includes a feedback adapter for course correction. The case study illustrates using DEF to standardize an organization's project estimation processes and templates by deploying new estimation models and tools over 6 quarters.
