The "User Requirements Specification" (URS) is a powerful document that can be used to:
- Set a vision for the system and the benefits anticipated
- Clarify scope and boundaries, and interactions with other systems
- Agree requirements between departments
- Assess software and suppliers, often as part of a tender document of some kind
- Ensure software demonstrations cover what's important
- Avoid risk of inappropriate purchases (and they do otherwise happen!)
- Steer implementation to achieve the benefits
It's common for key issues to be highlighted by preparing a URS, that would not otherwise have become apparent until too late.
Depending on the scope of the system, the document can be very short, or somewhat longer. It's a matter of being concise, but with sufficient detail to achieve its purpose. Aspects to cover include, inter alia:
- Business background and future
- Objectives and benefits
- Systems context, architecture and interactions
- Management information
- Functional requirements, highlighting core aspects and what may be different
- Transaction examples
- Sizing
- Existing systems, and any specific issues to address
- Technical preferences
- Supplier aspects
