Curious Cat Management Improvement Dictionary: Standardized Work Instructions, Visible Job Instructionsy

Standardized Work Instructions are an important part of Deming and lean manufacturing management systems. Processes need to be standardized and continually improved (kaizen). Without a documented standard process variation normally increases over time as processes drift away from the desired standard. As new ideas for improved are proposed those changes can be tested using PDSA and adopted if successful.

The key is not having a document that says "this is what the standard is," the key is having a document that is actually used. For that reason it is essential that the work instructions are easy to use (visible, obvious and as simple as possible) and easy to update (to avoid the common problem of the process changing and the work instructions losing touch with what is actually done).
