Staying in Control When Requirements Change: Learn Ways to Keep Schedules and Costs in Line
Poor communication is only one reason cost and schedule can deviate off track when systems and requirements change. Geographically dispersed teams, limited insight into possible change outcomes and manual—and therefore error-prone—requirements tracking can also present challenges. Additionally, companies developing complex systems are subject to an exceptional number of changes from external sources. Because they handle multiple development domains, they multiply their vulnerability to changes. And because organizations cannot control external change, they must manage it to be successful.
Ultimately, organizations must know how changing requirements in a complex system will affect other requirements, designs, tests and developed components. This is particularly critical for requirements where any unauthorized edit, mistake or miscommunication can have an extremely costly domino effect throughout the lifecycle. A global requirements change management process can increase the efficiency of the change control board through capabilities such as Web review and approval functionality as well as impact analysis.
An effective change management process can help you better identify how alterations will affect cost and schedule so you can keep them in control. This paper will explore change management approaches and how you can use IBM Rational® solutions to manage changes to development, system and IT artifacts.
