The five dos and don'ts of writing a URS

The five dos and don'ts of writing a URSWhen it comes to writing a user requirement specification, industry experts agree that there's usually room for

improvement.

Providing suppliers with a well-written user requirement specification (URS) is essential for developing new machinery or

packaging lines. A poorly written URS can result in miscommunication between the end user and the machine builder, which

turn can lead to time wasted rewriting documentation.

"The URS should define, clearly and precisely, what the user wants the equipment to do in terms of performance characteristic

product quality metrics, and production yields," says Dave Whittenton, business development manager at Rockwell Automatio[1]. "It should also define any nonfunctional requirements, constraints, and deliverables that need to be supplied with the

system."

Whittenton and Pete Oberst, project engineering manager for Remmele [2], offer tips on how to improve the URS process:

DOs

Interview all stakeholders. Who is going to use the equipment? Who is going to maintain the equipment? Who is going to be

responsible for the product? Each of these people has an interest in how the equipment isoperated. Their needs should be

included in the URS.

Work with the validation group to establish a validation plan. The time to plan for validation is at the beginning when you'rewriting the URS, rather than at the end when the equipment hits the floor. If you wait until the end, you're putting the cart

before the horse. This can lead to a compromised plan or the need to retest or requalify equipment.

Include a good overview. This section should describe the machine and what it's supposed to do. It should also include

background information, such as similar machines and processes currently being used.

Pay attention to word choice. Words like "shall" and "will" typically define requirements. Words like "may" and "ought" define

goals that are desired but not necessarily required. Make sure your word choice clearly differentiates requirements from desire

outcomes.

Include supporting documentation. If a standard or other specification is referred to, it should be included as an attachment.

DON'Ts

Don't use time-based metrics. Today, performance metrics are almost always written as a time-dependent measurement. Fo

example, "100 products per minute." This approach is too vague and does not take into account product yield and quality.

Don't use broad, sweeping statements. For example, "must be 21 CFR Part 11 compliant." Be specific about the elements

within the compliance. What part of 21 CFR Part 11 needs to be compliant? Which records do you need to comply with?

Don't cover functional requirement specifications (FRS) in the URS. The overall intention of the URS is to describe what the

equipment is supposed to do. How it performs is not a function of the URS.

Don't place multiple requirements in a single section. This makes it hard to test and validate each independent requirement

Each requirement should be numbered and stand on its own.

Don't duplicate requirements in multiple sections. You don't want the same requirements repeated in five different sections

of the document. This causes unnecessary work. Rather, collect the requirements in a general section and test them once.

Additional guidance may be found in the International Society for Pharmaceutical Engineering's (ISPE [3]) Good Automated

Manufacturing Practice (GAMP)Guide for Validation of Automated Systems. The JETT [4] (Joint Equipment Transition Team)

Consortium, a special interest group of ISPE, has developed documents and templates to help facilitate the URS process.
