What is needed instead is a systematic approach that gives you the results you need to decide which changes are making a significant difference and which changes can be ignored.

There are always too many possibilities. To illustrate, in Table 3-1 I tabulated some possible configuration factors from the subsequent chapters of this book. The important thing is to clearly identify the factors you wish to vary and then to pick a small number of levels that span the usable range for the factor.
