The purpose of this experiment is to evaluate the effectiveness of Perspective-Based Reading (PBR), as applied to requirements documents, by comparing it against another reading technique.

We designed this experiment to address three primary questions:

• If groups of individuals (such as during inspection meetings) were given unique PBR roles, would a larger collection of defects be found than if each read the document in a similar way?

• If individuals read a document using PBR, would a different number of defects be found than if they read the document using their usual technique?

• Does a reviewer's experience in the role influence performance when using PBR?

• Constraints on the participants
• Other requirements
• The design itself
