Temporary Process Deviations: Scope, Expiry and Closure

A temporary process deviation needs a defined reason, affected scope, authorised decision, expiry trigger and return-to-standard check. Keep it separate from the permanent work instruction and stop using it when its approved boundary is reached.

A missing fixture or an impractical instruction can lead people to improvise. Recording the improvisation does not make it approved. The production supervisor should raise the issue, while the designated engineering and quality roles decide whether a controlled temporary method is permissible at all.

Separate observation, proposal and permission

Record what was observed, the current instruction and the reason it cannot be followed. Then write the proposed temporary method in a separate field. Identify affected safety controls, product requirements, customer approvals and inspection needs. Required controls remain in force; an urgent order is not authority to bypass them.

HSE’s procedure guidance recommends user involvement, task analysis and procedures suited to the work. It also warns against relying on procedures alone to control hazards. Use the review to repair the work conditions as well as the wording. The register here is an original operating aid, not permission for a hazardous modification.

Make the permission finite

The quantities and time are illustrative limits, not a recommendation for your process. An expiry can combine date, quantity, lot or a specific event. State which limit takes precedence. “Until fixed” is too vague to establish whether the next shift is still authorised to proceed.

Before work starts, the supervisor verifies that the people doing the task can access the approved temporary instruction and distinguish it from the standard method. Where a customer requirement changes, obtain the required customer decision through the normal authorised channel. An internal approval cannot silently alter an external requirement.

Keep affected output inside the boundary

Log each affected unit, carton or lot using the identifier appropriate to the process. If 54 cartons have been completed and the next pallet contains 12, only six cartons remain inside the illustrative quantity limit. The team must resolve the boundary before processing the pallet; completing 66 and backdating an extension would destroy the control.

If expiry occurs, a condition changes or the temporary method fails its checks, stop using the deviation and refer the affected output for the prescribed review. An extension is a new recorded decision with a reason and revised boundary. Retain the original expiry and all work performed under it.

Close with restoration evidence

The process owner checks that the normal equipment, material and instruction are available again. Quality resolves affected product status. The supervisor removes or marks obsolete temporary copies at the point of use, and confirms the next shift has the correct method.

Close the record only when the affected population is identifiable, all required inspections and dispositions are complete, and restoration has been acknowledged. If the temporary method should become permanent, use the normal controlled-change process. Repeated extensions are a prompt to investigate the unresolved cause, not evidence that the method is acceptable forever.

Keep temporary and permanent instructions distinct

Our Optiwise forms support role access, mandatory fields, attachments and form versions. Our versioned SOPs preserve instruction history. Configure a deviation record with its scope and expiry, and link the approved instruction to the relevant production work. The accountable roles still make the technical approval and release decisions.

Deviation questions

Can an operator approve a workaround because it worked before?

Prior use does not establish approval. Record the observation and use the designated engineering, quality and safety review for that task.

What if a deviation expires while a job is unfinished?

Apply the defined stop or hold rule. Resume under the standard method or a newly authorised decision, preserving the original record and affected-output boundary.
