How to write a good procedure and work's instructions in a way that anybody can understand it and maintain the safety and quality in the same time?

Best way write instructions and procedures is making them visual with pictures. Not all the workers may understand the language used in the instructions, but everybody understand pictures.

Key steps must be photographed (as much possible in colour) and arranged in a sequence in the instruction sheet with key information / data written near to them.

Demonstrate "Dos" and "Donts" in the instructions so that people become aware of what care they must take.

Procedures and work instructions are not always the same thing. Procedures points to the tools to use and when to use them but they don't tell you how to use them. Good procedures and/or work instructions comppose of the following:

- Prrequisits to start the work and this includes health and safety issues and the team required to do the job.

- Clear steps to accomplish the job written in the language(s) of the people doing the job and using graphical illustrations wherever possible. This includes safety instructions and in-process quality measures, how and where to record the results of each step (if required for tracking purposes), reference to standards and operation manuals, exception handling.

- Handing over the completed job to the next stage

Good procedures and/or work instructions must be tested and approved by the person(s) accountable for doing the job.

Huge problem in my field (oil refining) Engineers assume people are up to their level of knowledge. When you write a procedure, imagine you are the person following it without the advanced knowledge. Then have a person in that skill level read it to see if it makes sense.

its that simple,

Procedure should be built as a view chart.

Work instruction should be visualized (with pictures) shows all steps .
