The document defines a User Requirement Specification (URS) as the first document created to define procurement requirements for any equipment. It describes what information a URS should include, such as the purpose of the equipment, intended use, specifications. The document provides guidelines for creating a URS, including defining clear requirements, obtaining necessary approvals, and ensuring requirements are testable. It lists key sections that should be included in a URS, such as objective, scope, technical requirements, material specifications, safety features, and documentation requirements. Creating a thorough URS helps both users and suppliers understand requirements to design equipment that meets all needs.

URS - USER REQUIREMENT SPECIFICATIONS
What is URS?
The URS means User Requirement Specification is a first document to define the procedure for the procurement of any equipment.
The user requirement specification document should be very clear why we need this equipment and for which area and application.
User Requirement Specifications also known as URS is a document, which describe the basic requirement of any Equipment, Instrument, System or
Facility in terms of Make, Model, capacity, Process, Control System and other cGMP requirements.
BASIC FLOW FOR PREPARATION OF THE URS IS AS BELOW:
➢ Generally URS is prepared by the Person from the user department.
➢ After preparation of the URS it will be reviewed by user department, engineering department, Quality Assurance. If required it can be reviewed by
other cross functional department also.
➢ After review by cross functional department, it will be sent to QA Head for approval.
➢ Once the URS is approved it will be sent to Vendor for approval. Once approved by vendor Purchase order shall be raised.
➢ In some cases where equipment is commercially available, URS may not required to be prepared. For such equipment technical & functional
specification from vendor can be considered as URS. For example in-process testing instruments like Hardness Tester, etc.
A properly written URS helps the supplier or vendor to fully understand the client’s requirements. This, in turn, helps the supplier design a system or
specialized equipment that completely satisfies needs and expectations. Alternatively, if there is no URS, it can create confusion between both parties
blaming each other for failures resulting in the waste of time and resources.
A URS also helps with the completion of regulatory requirements. Some regulatory bodies require that the URS is completed before the purchase of
any equipment. It also forms a basis for validation activities including installation qualification (IQ) and operational qualification (OQ).
During User Requirement speciation preparation keep the documents as per all the regulations like environmental safety, machine safety
controls, and health shall be considered.
The following guidelines should be followed during the preparation of the URS:
➢ Each requirement statement to be uniquely referenced and no longer those 250 words
➢ Requirement statements should not be duplicated or contradicted.

➢ The URS should express requirements and not design solutions.
➢ Each requirement should be testable.
➢ The URS must be understood by both user and .supplier; ambiguity and jargon / terminology should be avoided.
➢ The use of diagram is often useful.
➢ The scope for readers to make assumptions of misinterpret should be minimized.
➢ Wherever possible, the URS should distinguish between mandatory / regulatory requirement and desirable features.
Points should be considered in the user requirement specification format or Key Sections of a URS:
