计算机化系统 3: 用户需求规范(URS)
URS是供应商招标、选择、评估的基础,同时也是验收和验证最基础的文件,内容必须保证涵盖业务流程的关键方面和GMP的要求。
<A User Requirements Specification (URS) is a description of WHAT the computerized system is supposed to do from a System User’s point of view, independent of a specific solution. It must be in accordance with, and link to, the business process.
This template refers to all software categories, not all chapters are required for all categories. All chapters of this document should remain in the document. Where a chapter is not applicable, please insert “n/a” to assure that each section has been considered.
The sections below include instructions, examples and partly standard requirements. Please adapt them to the specific circumstances of the system.
Characteristics of requirements:
• Each requirement is uniquely identifiable to permit traceability (e.g. alphanumeric).
• User requirements must be complete, that means fully defined, clearly stated, objective, verifiable and feasible for their intended use with regard to the respective business process.
• Each numbered requirement must describe in clear language one specific and distinct aspect that the system should fulfill.
• User requirements must be specific enough for testing and checking
• Requirements must not contradict each other
• If there is a dependency between two or more requirements, this should be noted, defined and cross-referenced.
• If a requirement is specified, detailed or explained in another document, the reference to this document is provided and the referenced document must be easily retrievable
• User requirements must support full traceability through the test protocols
• It should be stated whether the requirement is mandatory or optional.
• If relevant for the requirement, also describe the area of the business needing the functionality.
• If a requirement is needed under specific conditions, these conditions should be noted.
The URS should have a direct link to User Acceptance Test Protocol later on.
The Functional Specification describes, at a high level, how the requirements defined in the User Requirements Specification are implemented in the system.
以下内容应该涵盖在URS的内容里面:
1 Introduction
2 Overview
3 Functional Requirements
4 Data Requirements
5 Business Role Requirements
6 Electronic Records and Signatures Requirements
7 Security Requirements
8 Interface Requirements
9 Technical Requirements
10 Performance Requirements
11 Environment Requirements
12 Migration Requirements
13 Out of Scope
14 References
