Author's note: In attempting to reconcile mainstream industrial literature with service management and IT service management, I developed the following two-dimensional analyses for my book revision. Given that industrial theory is not my primary area of study, I am wondering if I am reinventing wheels. Certainly, I am not yet happy with the analysis below. Comments greatly welcome.
I have some citations from John Seddon's overview of "Rethinking Lean Service" that I intend to track down for greater perspective in these matters (Levitt, Chase, etc). This is written with awareness of the controversies surrounding Lean applications to services.
In exploring the applicability of manufacturing principles and trends such as Lean to IT management, it is useful to consider the various manufacturing models, or “environments,” that have been identified in the mainstream industrial literature. The major continuum (as defined by APICS, the American Production and Inventory Control Society) is:
- Make to Stock
- Assemble to Order
- Make to Order
- Engineer to Order
in order proceeding from higher volume, more standardized products, to lower volume and one of a kind products.
