Standard work is the current best-known method for a task, written down and actually followed — typically the sequence, the timing, and the inventory needed at the step.
It is the precondition for improvement rather than its opposite. Without a standard there is no baseline, and without a baseline an improvement can be asserted but not demonstrated. If three people do a task three ways, changing one of them proves nothing about the task.
Who writes it decides whether it survives. A standard written by someone who does not do the work describes how the task is imagined to go, and the distance between that and reality is exactly where it quietly stops being followed.
The word “current” is doing real work in the definition. A standard is the best method known today, and each improvement replaces it. One that has not changed in three years almost never means the method was perfect; it means improvement stopped.
The common failure is a standard written for audit and filed in a binder. If it does not live at the workstation it is compliance material, and that is a different artefact even when the words are the same.
