After a failure things have to be done: reparing or ordering new part, taking safety measures, cleaning, etc. After the daily meeting new improvement actions can be drafted. You can now make new action lists immediately. Assign a responsible person and he/she kan assign the execution of the task to someone else. The task is added to the executor's to do list. The status of the action is easy to follow by the responsible person and/or managers.
After each act a comment can be added and the status of the action can be changed, if it has changed. Nothing gets deleted. The whole process of the action can be followed and is secured. Operations management has great overview over all actions.
Operators who have suggested improvements can actually see if the suggestion is picked up and taken into actions. This creates more involvement among employees.
