Underlying principles of Learning Curves I Each time you perform a task it takes less time than the last time you performed the same task 2. The extent of task time decreases over time 3. The reduction in time will follow a predictable pattern CTle McGraw-Hill Companies, Inc, 2004

Example of a Learning Curve Suppose you start a Term Time(in term paper typing paper Minutes) business, You time yourself on the first 100 paper, then the second, 90 and so on Note that only 90 of 100 minutes are used in the second 23456 84.62 81.00 78.30 repetition. This is an 76.16 example of a 90% learning curve CTle McGraw-Hill Companies, Inc, 2004
