Additionally; CLM is an industry term for "Configuration Lifecycle Management". Several vendors offer CLM solutions [see https://en.wikipedia.org/wiki/Configuration_lifecycle_management for an introduction.] IBM's CLM offering is the Jazz platform: RTC, RQM, DNG etc.
While IBM CLM does include configuration management of product/application design and software construction, in our case "CLM == Collaborative Lifecycle Management" is our take on ALM -- application lifecycle management.
