When we first approach Pharmaceutical Quality Management Systems (QMS), we are usually directed to rigid textbook methodologies. These standards insist on a set hierarchy: the Policy, the Manual, the Standard Operating Procedure (SOP), and the ubiquitous Work Instruction.
But there is a reason you won’t find Work Instructions in my document pyramid. The truth is, they aren’t a mandatory requirement for every business model. When we blindly incorporate them—often just to impress auditors—we end up with a bloated system that is unnecessarily complicated and rarely used.
When Are Work Instructions Actually Relevant?
In pharmaceutical manufacturing, where quality control, analytical testing, and complex—and expensive!—equipment are the heartbeat of the operation, work instructions are essential. The stakes are high, and the margin for error is razor-thin.
However, the requirements of pharmaceutical manufacturing are vastly different from pharmaceutical distribution. In distribution, the goal is agility and velocity. If you are spending excess time maintaining unnecessary or unutilized documents, you are not improving your process; you are prioritizing documentation bureaucracy.
In a distribution setting, I view work instructions strictly as technical guides.
How and When to Use Them
Every process does not require a work instruction. Use them only when technical complexity demands it:
- Hardware Troubleshooting: A quick-reference guide for tasks that are infrequent but high-risk, such as calibrating a specific printer model or changing complex ink systems.
- Software Workflows: Simple 1-page cheat sheets for navigating difficult to navigate modules within your ERP system to prevent repetitive user errors.
These should be linked directly from your SOPs so employees can pull the granular details exactly where and when they need them. Avoid pages of text; rely instead on diagrams, annotated screenshots, quick screen-shares and other video demonstrations.
Designing for the User, Not the Auditor
It is vital to remember that we are writing for our audience—the people doing the work—not for our auditor.
As the scope of a business increases, your QMS documentation should evolve with it. But evolution really only means “adding what is necessary.” Each document you produce must assist the flow of the employees—enabling easy movement from task to task, procedure to procedure, and duty to duty—to drive the business process forward.
Your QMS is not a library. Start building a system that guarantees operational efficiency.
