Part/component purchases are a shared responsibility between the company and CM. Company-controlled suppliers have negotiated pricing and purchased orders may be placed by the company or the CM for long-lead and specialty items.
Ultimately, the liability for part/component inventory rests on the company. For this reason, minimizing inventory, maximizing inventory turns, and value stream flexibility are some major objectives of managing a CM.
The objective of CM value stream management is to continuously match capacity with demand (even if demand ‘suddenly’ changes).
A value stream map is useful to illustrate the critical functions of this model as follows:
Note that sales forecast accuracy is a key input to operations and usually handled by the Sales & Operating Planning (S&OP) process, which is out-of-scope for this particular article. (Sales forecast accuracy is a KPI for sales or business development during S&OP.)
