4 Why is Requirements Definition nd Mngement so Importnt? Forml methodology Stndrd infrstructure 6% Executive support Experienced Project Mnger 15% 14% 5% 5% 5% Skilled Stff Relible Estimtes 12% 7% Minimized scope 17% 14% Agile requirements process Cler business objectives User involvement Source: Chos Chronicles, III, Anlysts report tht s mny s 71 percent of softwre projects tht fil do so becuse of poor requirements mngement, mking it the single biggest reson for project filure bigger thn bd technology, missed dedlines or chnge mngement fiscoes. CIO Mgzine, November 2005 If you do post-mortem evlution on unsuccessful softwre projects, you'll find tht most of them filed becuse the person responsible didn't properly mnge the project's requirements nd expecttions. -Andy Feibus 4

5 Telelogic Mrket nd Technology Leder in Requirements Definition & Mngement Telelogic is " leding vendor in requirements mngement solutions, nd it continues to innovte nd provide tools tht re powerful yet usble. Appliction Development Technology Audit- Requirements Mngement Solutions, Teres Jones, Butler Group, Februry 2006 Telelogic is mrket shre leder in Requirements Mngement with 37.1 % in 2006 Grtner Dtquest,

6 Connected Requirements Approch Cptures the voice of the customer Defines customer requirements Prioritizes the requirements Differentites between essentil requirements nd those tht would be nice to hve but re not vitl to the success of the project Optimizes cost/benefit rtio Defines requirements in sufficient detil to drive the development process Provides level of trcebility tht is just enough to stisfy governnce, complince, nd uditing requirements Uses requirements to guide the implementtion of hrdwre, softwre, electronics, embedded systems, etc. Vlidtes requirements during test 6

7 Requirements Lifecycle Mngement Elicit nd define business/user requirements Vlidte requirements Anlyze requirements to define the solution Drive implementtion from the requirements Drive testing from the requirements Mnge trcebility nd chnge 7
