Présentation de l'étude de marché - Description & Table des matières
 Requirements-based testing

Errors in requirements are a major source of waste in IT. There have been attempts to reduce the problem, but until recently they have suffered from being dispersed and unco-ordinated across the lifecycle. As enterprises become increasingly interested in cross-discipline application lifecycle management (ALM) solutions, requirements-based testing re-emerges to address the problem in an integrated way. It combines methods from requirements engineering and software testing into an orchestrated set of quality assurance activities and management tools that focus on getting the requirements right from the outset, managing inevitable change and discovering requirements errors before they become extremely costly to fix.
