What You Should Walk Away With See first that the design is wise and just;That ascertained, pursue it resolutely-- William Shakespearewww.PerfTestPlus.com 2006 PerfTestPlus, Inc. All rights reserved.RUP for DummiesPage 3

The Rational Unified ProcessRUP Process Made Practical- Sustained development ofquality software- Delivered on-time and on-budget- Requires more than “heroic” individuals- Cohesive teamwork & common understanding ofdevelopment tasks- Ensures implementation is predictable and repeatablewww.PerfTestPlus.com 2006 PerfTestPlus, Inc.

The Spirit of RUPAttack major risks early and continuously- Or they attack youUse working software as primary measure of progressCompleted plans, requirements, and design are good - workingsoftware is betterProduce only artifacts you need- When in doubt, don’t produce itAccommodate changes in requirements and design- Allow for changes, but manage themwww.PerfTestPlus.com 2006 PerfTestPlus, Inc. All rights reserved.RUP for DummiesPage 8

The Spirit of RUPEnsure that you deliver value to your customer- Design, implementation, and testing address customerneeds- Documenting customer needs is good, implementingthem is betterBaseline an executable architecture early- First build the skeleton structure, then fill in the holesWork closely as one team- Affects organization, tooling and team valuesQuality is a way of life, not an afterthought- Quality from the beginning, quality by designwww.PerfTestPlus.com 2006 PerfTestPlus, Inc.

Agenda Phases: Overview The software lifecycle of the Rational Unified Process (RUP) is-Four sequential phases,Each concluded by a major milestone;At each phase-end an assessment is performed todetermine whether the objectives of the phase have been met.A satisfactory assessment allows the project to move to the nextphase.www.PerfTestPlus.com 2006 PerfTestPlus, Inc.
