Practical example

Work instruction versus procedure
A procedure may describe a broader process and responsibilities. A work instruction normally provides detailed guidance for one specific task.
Digital work instructions
A CMMS can attach instructions to preventive-maintenance plans or work orders so the technician receives the correct information at execution time.
Common mistake
Instructions copied from a manual without adapting them to the actual plant asset, access conditions, safety controls, and tools may be difficult or unsafe to use.
How this term differs
Work Instruction is detailed instructions for performing a specific activity. It is related to Maintenance Task List, Maintenance Standard Operating Procedure, and Maintenance Work Package, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
