Understanding the Transaction Analysis Worksheet
Cycle time is defined two ways: event time, the time spent from start to finish on the tasks assuming no lag time; and elapsed time, the actual time that passed from start to finish, including wait time for steps like ”get approval”. Lean manufacturing principles would associate this measure with process-cycle efficiency.
The constraint is somewhere in the approval process. If the issue is policy, then no amountof technology will break the constraint. When a transaction is viewed this way, shortening event time will only make a nominal productivity improvement in most transactions. The real improvement is in elapsed time and yield.
Yield is the number of transaction requiring no rework. It’s measured as a percentage of the total. Business rules are policies and informal guidelines that govern decisions and behavior.
Disconnects are issues that result in gaps in elapsed time or event time, and bring yield below 100 percent.
