QA: BRD, SRS, and Test Plan
BRD, SRS, and Test Plan
BRD
The Business Requirements Document
This document outlines the Business needs that justify the development of a product, the features required to meet those needs, and how those features should look to end users. This document is not necessarily concerned with HOW to achieve the feature, only that a functionality is required.
SRS
The System Requirements Specification relates back to the BRD and provides the technical details on how to accomplish each BRD requirement.
If the BRD includes an 'Account Deletion' feature, the SRS would typically describe the Account Deletion form fields, authentication rules, and visual elements such as buttons. Authentication architecture might be described elsewhere in the SRS and only referenced in that specific section.
