Telecom Expense Management is so blase.  Telecom Lifecycle Management is fresh.  When you examine it closely, it is difficult to tell the difference between the two.  Which one is right for you?  The answer may not be as simple as you think.

Usually, TEMs are viewed as providing a very short term engagement, where they reduce costs quickly.  TLMs are expected to provide a holistic view which might begin at expense management but would also look at order fulfillment, asset management, managing SLAs, and on and on.  But is it unrealistic to expect long-term savings from short-term engagements?  No.  Any TEM/TLM should be able to provide recommendations for extended savings.  The biggest obstacle to maintaining and increasing savings is your organization.  Loss of efficiency usually takes place when there is no communications between people negotiating contracts and people ordering services, and when there are no quality management processes in place to monitor activity (MACD, Contract maturity, organizational changes).

TLM is something that you should be getting from any vendor, but it is only achievable with buy-in from your organization.  Monitoring processes from cradle-to-grave is the only way to achieve long-term savings.
