What Is User Requirement Specification in Pharma

The purpose of a design qualification is to ensure that the design intent meets the user`s requirements and is suitable for the intended use. The design qualifications also verify the integration of risk controls (critical aspects) identified during the systemic risk assessment into the final design so that manufacturing can begin. Proof that the requirements are met (as defined in the user requirements specifications and documented in the design qualifications) is verified by the execution of the tests. The responsibility according to the expert, including the owner of the device, should write URS, enter additional entries from a technical point of view and recheck compliance with regulatory requirements. The development of URS at this level is unique in most industries, but is standard in strictly regulated industries as it is an important element in creating quality software. The Level 3 document of the User Requirements Specification contains all traceability considered mandatory for software considered essential to product quality in pharmaceutically regulated industries. The revision of the BG5 covers automated devices and systems. All other computerized systems are under the responsibility of GAMP. ® The GAMP® describes a risk-based, science-based approach to hardware and software development.

For process automation/control systems connected to systems and devices, user requirements for each system must match when it comes to controlling critical process parameters, alarm management, and data management. These aligned user requirements are verified using an integrated testing strategy. The User Requirements Specification describes the company`s requirements for what users need from the system. User requirements specifications are written at the beginning of the validation process, usually before the system is created. They are written by the system owner and end users with the contribution of quality assurance. The requirements described in the URS are typically tested in performance qualification or user acceptance tests. The specifications of the user`s requirements are not intended as a technical document; Readers with only a general knowledge of the system should be able to understand the requirements described in the URS. The URS and functional specifications define the properties of devices, rooms, load-bearing systems or other systems.

At this stage, it is necessary to define the basic elements of quality and reduce GMP risks to an acceptable level. Specifying user needs should be a reference point throughout the validation lifecycle. The User Requirements Specification (URS) is a formal document that defines the requirements for the use of the software system in the intended production environment. The specification of the user requirements is created by the end user, who extrapolates the requirements directly from the production processes. These high requirements for end users are then passed on to engineering, which has the task of transforming them into a complete procurement package. A package that covers all aspects of purchasing, installing, and operating the specified system. In addition to these direct requirements, there are also a variety of indirect requirements, such as.B.; Documentation, manpower, training and testing equipment that must be fully researched, reviewed and specified. The specification of the user`s request must be written in a format that verifies that each of these user requirements is “fully met” or not met. In the case of the chromatography data system (CDS), it is also important to define the requirements for the basic functions, taking into account the following details: Learn how to prepare a User Requirements Specification (URS) that optimizes your entire validation task.

Whether it is a purely mechanical system or a mixture of electromechanics or exclusively software, the successful compilation and execution of the installation qualification (IQ) (for installation), operational qualification (OQ) (for functionality) and performance/product qualification (PQ) (for usability) depends on an URS that contains clear, concise and verifiable requirements. At LFA, we understand the importance of committing to purchasing capital goods. That`s what we have, an URS template that your team can use. Do not hesitate to contact us and we will send it to you. This way, when you buy a rotary pill press or a portable tablet press, you can set exactly the equipment you need. Each requirement listed in a specification of user requirement in terms of product safety, identity, strength, purity and quality must be identified exhaustively. Therefore, quality assurance (QA) must play an important role in reviewing and approving the final list of requirements and approving changes to user requirements that may affect the above product or process attributes (p.B. cGGP).

First, the specification of end-user requirements, or URUs as it is commonly known; is documented, agreed and approved, they form the basic document URS level 1. Engineers (or vendors) can then begin the preliminary design to determine exactly what functionality is required for each of the elements specified in the user requirements specification listed in the end user requirements. Once this feature is documented and approved, it forms the URS Level 2 document. This is the last step of the URS, unless software is used. Critical quality attributes and critical process parameters are important inputs in the specifications of user requirements as well as in the ordering and qualification process for quality risk management and must be identified before creating specifications of user requirements. (Chapter 3) The specifications of the user`s requirements do not include everything, e.B. the content of the technical specifications and standards is not repeated. User requirements specifications provide a vehicle to inform the responsible designer of the specific requirements that they can use to develop equipment specifications for the purchase of equipment. Q: Are user requirements specifications still required for validation? A: When a system is created, user requirements specifications are a valuable tool to ensure that the system does what users expect of it. In retrospective validation, in which an existing system is validated, the user`s requirements meet the functional requirements: the two documents can be combined into a single document. The user requirements specification document contains requirements from multidisciplinary sources and supports design, commissioning and qualification, operation and maintenance activities.

Here are some of the answers to FAQs from previous workshops: User requirements specifications are a living document and changes are driven by changes in requirements. .
