2. Functionality developed  5%25%60%10% Think of OO phases as landmarks, each evolving a system to a certain extent Percentage of functionality delivered: - Of total volume of functions - Of operational level of system’s functionality (all 15% from Inception & Elaboration refers just to one key function; OO methodology insists on doing hardest part first) Adapted from Prentice Hall 2004 ©

4. Variation 1: System Broken to Different Functionality Domains (Sub-Projects) - Grouping of OO Phases on Sub-Projects Sub-Project 2 Sub-Project 1 Reading: Most of Planning, Analysis and Design fall into Inception and Elaboration phases, while most of implementation and operation fall into Construction and Transition phases.
