1. The UP has a long and proven history 2. There are many flavors of the UP available to you 3. One process size doesn’t fit all 4. The UP can be extended to the entire IT lifecycle 5. The UP is clearly evolving IBM Software Group | Rational software Some History www.enterpriseunifiedprocess.com/essays/history.html

These principles are the basis for RUP practices. IBM Software Group | Rational software RUP Practices

.Manage risk .Leverage legacy systems .Execute your project in iterations .Build high-performance teams .Embrace and manage change .Organize around the architecture .Measure progress objectively .Manage versions .Test your own code .Leverage patterns .Leverage test automation appropriately .Architect with components and .Everyone owns the product services .Understand the domain .Actively promote reuse .Describe requirements from the user .Model key perspectives perspective .Rightsize your process .Prioritize requirements for .Continuously reevaluate what you do implementation ®

© 2006 IBM Corporation IBM Software Group | Rational software What Is OpenUP/Basic? An iterative software development process that is minimal, complete, and extensible. .Minimal - only fundamental content is included .Complete - can be manifested as an entire process to build a system .Extensible - can be used as a foundation on which process content can be added or tailored as needed IBM Software Group | Rational software OpenUP/Basic

.The UP has a long history and is well established within the IT community .There are many flavors of the UP available to you From very agile to “traditional evolutionary” From very sparse to very thorough .One process size doesn’t fit all You will likely need several instantiations You will need to provide guidance as to which flavor to follow .The UP can be extended to the entire IT lifecycle .The UP is clearly evolving IBM Software Group | Rational software
