Aspects of the present invention include a method, system and computer program product determining, scoring and reporting the complexity of customer and test environments and workloads. The method includes a processor performing an accounting of factors related to complexity of a plurality of environments and workloads; determining one or more formulas to use for determining an overall score and ranking for each one of the plurality of environments and workloads; collecting relative environment and workload data; determining a complexity score for each one of the plurality of environments and workloads; and determining a complexity ranking for each one of the plurality of environments and workloads.
