Chapter 6, "Process Management," covers Drum-Buffer-Rope for Services (DBR_S). Though it compares a few basic capacity management scenarios for an entire process, it does not explore the dynamic behavior of elements within that process. It thus treats the process itself as a black box. Fortunately, the basics of DBR_S can be appreciated without an understanding of internal process dynamics.

In case you want to probe a bit deeper, however, this appendix contains some DBR_S simulations. In effect, this appendix opens the lid a bit and shines some light inside the black box covered earlier. ...
