Many organizations implement IT to compete more successfully. The Customer Resource Life Cycle (CRLC) has been proposed as a framework for explaining how they do this. The current research investigated their use of IT in CRLC activities for this purpose. Four hundred seventy two managers responded to an e-mail survey about an IT application in the context of the CRLC. Statistical tests validated the CRLC’s four stages. Requirements and Acquisition stages predicted Porter’s three generic competitive strategies. Retirement predicted only one strategy.
