Identify redundant environments or the need for more test environments


Click Show relationship among testers.


Redundant test environments are suggested:


1. When there is a strong association between two enivironments (indicated by long vectors and a small angle) 

2. When the asociation is consistent across years


Need for more test environments (within a single mega-environment) are suggested if:


1. There are large gaps among test environments,

2. This is consistent across years, and


Note But: obvious gaps among environments may be strong evidence of the existence of different mega-environments.
