Set-up standardization and its impact on OEE
Companies are aware that production planning has to take into account each type of set-up time.
Practitioners admit that they need set-up time standardization (SOP for set-up) for: (1) increasing flexibility and (2) continually improving set-up time. Sometimes, it is difficult for them to convince managers that for this set-up time no production should be planned (as with other scheduled downtime: waiting for materials, planned maintenance, etc.). Set-up standardization (SOP) is achieved through SMED (the path with small steps), MDC (the innovative path) etc.
But the set-up standard can generate significant variations. I often explain to practitioners that only negative variations, those that generate overtime, should be included in the OEE structure. For these variations, from a certain level upwards, I recommend the development of projects to solve problems (for example with A3) in order to re-fit into the set standard or KAIZEN projects to restore/improve the set-up standard.
So, to you, the SOP for set-up time are in the scheduled downtime structure? Is set-up overtime included in the OEE? Do you run problem solving projects and KAIZEN projects for set-up?
