Customer lifecycle management or CLM is the measurement of multiple customer related metrics , which, when analyzed for a period of time, indicate performance of a business. The overall scope of the CLM implementation process encompasses all domains or departments of an organization, which includes all sources of static and dynamic data , marketing processes, and value added services to a unified decision supporting platform through iterative phases of customer acquisition, retention, cross and up-selling, and lapsed customer win-back. 
Some detailed CLM models further breakdown these phases into acquisition, introduction to products, profiling of customers, growth of customer base, cultivation of loyalty among customers, and termination of customer relationship. [ quote needed ]
