Total Cycle Time ??
Total Cycle Time ( TCT ) is the combined effect of the cycle times of all business processes from the time a need exists until it is satisfied. More simply, it is the total time it takes to get things done, to bring a new product from concept to cost-effective production or to take an order for a product or service and satisfy the customer's need.
These are not just sequential processes but are all concurrent and sequential processes involved in running a competitive business. Frequently the cycle times of these processes are rolled up into one or more measures to be used as the primary drivers of competitiveness improvement.
Cycle time is the total time from the beginning to the end of your process, as defined by you and your customer. Cycle time includes process time, during which a unit is acted upon to bring it closer to an output, and delay time, during which a unit of work is spent waiting to take the next action.
In a nutshell - Cycle Time is the total elapsed time to move a unit of work from the beginning to the end of a physical process. (Note, Cycle Time is not the same as Lead Time).
