Assessing whether an SOP works at the point of use
An approved procedure provides an agreed description of how an activity should be performed. Its effectiveness also depends on whether the person carrying out the work can understand the instructions, access the necessary information and recognise when the activity should stop or be escalated.
A technically correct document can still be difficult to use. Responsibilities may be dispersed across several sections, instructions may rely on undefined judgement, or critical information may appear after the step to which it relates.
I find it useful to review a procedure alongside the actual activity. Can the operator follow the sequence using the equipment, materials and records available? Are the specified checks achievable at the point they are required? Does the procedure account for the conditions in which the work is performed?
The assessment should include foreseeable departures from normal operation. An instruction to 'inform QA' needs enough context for staff to understand when escalation is required, whether work can continue and how the immediate situation should be controlled.
Similarly, acceptance criteria need to support a consistent decision. Terms such as 'satisfactory', 'appropriate' or 'clean' may require further definition, depending on the activity and its significance. Where professional judgement is necessary, the decision-maker and the basis for that judgement should be clear.
The supporting records should follow the work. If the form requires staff to reconstruct events later or record the same information in several places, the design warrants review. Unnecessary complexity can create opportunities for omission and inconsistency.
In my view, involving experienced users during development provides a valuable check on practicality. Their input should be assessed alongside the technical requirements and the controls needed to protect product quality.
Training then needs to reflect the task and the significance of any changes. A recorded acknowledgement provides limited evidence that someone can perform a complex activity competently.
A useful final review is to observe the procedure in use and consider where staff hesitate, seek clarification or rely on knowledge that the document does not contain. Those points can identify opportunities to improve both the instructions and the process.
