Control

In the Control Phase we first made certain that this was an improved process by use of a control chart where we could see the difference between now and before we began the project.


Once decided that this process was better, by means of variation and a new higher mean output. We next wanted to control the new system. This will be achieved with Standard Work and whiteboards showing the progress they should be adhering too.
This works by having slots on the board that have a target in them depicting how many units they should have produced by that time.

The Above example is using the old skin on the board and will be updated.

This is made more visual by colour coding  the boards, all entries on target will be entered in green while any entries above or below the target are entered in red.

There is also a time series plot on the board that is filled in at the end of the shift by the Group or Team Leads.

These boards will be reviewed every shift to view progress, also audits will be done weekly by support staff to ensure the standard work is being followed.

The boards are also where the product builders will record any issues and reasons why the target has been missed.

These controls will help prevent the new process from regressing and also been reviewed 3 times daily will help drive any recurring issues being fixed.
