I would therefore suggest that a linear process only occurs when you are ready to do the final installation and commissioning of Grouper. By this point in time you should have a detailed plan which you can follow step-by-step. Up until this point I would suggest that you follow a simple process:
The core Grouper binary is easy to install, and so installation will be relatively easy (not much more difficult than installation of the quick start). The interesting stuff really begins with the installation of the database, and configuration of data connections. It is at these stages that the process can be used. At first you will encounter errors and other problems, but as you continue your knowledge of Grouper will increase. It is important at each iteration of the process that you have realistic expectations of what represents success at that specific stage. For example, at first a reasonable expectation would be to get a working Grouper database
