Manage changes in the requirements definition through a collaborative effort

Abstract

Updating or changing the requirements statement during the systems engineering process may impact adversely on project parameters such as sequence, dependencies, effort, and duration of tasks, usually with an increase in development time and cost. Changes in the requirements statement that results in conflicting requirements may also have a negative impact on the system solution. Reasons for changes to the requirements statement during the systems engineering process and the origins of these changes will be discussed. Finally, this paper looks at how to manage changes to the requirements statement by using an integrated data repository in a model based systems engineering environment with a communication protocol that allows for real time collaboration where all stakeholders and the development team can contribute throughout the systems engineering process.
