Document Types

PM360 supports five BA document types, each with a specific purpose and optional starter template.

TypePurposeTemplate Sections
BRDBusiness RequirementsExecutive summary, business objectives, scope, stakeholders, functional/non-functional requirements, constraints, assumptions
FRSFunctional RequirementsDetailed functional specifications derived from the BRD
SRSSoftware RequirementsIEEE 830-aligned, procurement-grade specification. Includes performance, security, interface, and design requirements
SDDSystem DesignArchitecture, component design, deployment, security, data model. Written post-SRS
User StoryAgile Stories"As a [user], I want [goal], so that [benefit]" format with acceptance criteria

When to Use Each

  • Start with a BRD for high-level business requirements
  • Derive an FRS for detailed functional specifications
  • Use SRS when a formal, procurement-grade specification is needed (government tenders)
  • Write the SDD after the SRS is approved, detailing the technical solution
  • Use User Stories for agile teams working in sprints
