Hello, I am creating the process map for our very small CNC machine shop and I'm having trouble with KPIs. This is the current map. I'm having trouble identifying a KPI for manufacturing, as manufacturing and purchasing are closely related. I can't really use On-Time Delivery, because issues with purchasing could cause us to be late. I can't really use Product Quality, because again issues with purchasing could impact Product Quality. I'm wondering if you have any ideas on how to approach this and what processes/KPIs your organization uses. Should I just combine the two? Thanks!
