A strategic product/service requires further analysis before one can decide whether to make or buy from a strategic standpoint. Specifically, if the strategic product/service can be broken down into families of components and parts that are also strategic, it should be made in-house. On the contrary; if it is not divisible or its components or parts are not strategic, it should be outsourced.
* Note: In some cases, it is not possible to make an item in-house in the short term. This may be the result of budget constraints, capability problems, capacity limitations, etc. In these cases, the item must be outsourced.
