Structured estimating
The basis of past experience to predict future events
- Accuracy of estimating depends on the experience of the estimator
- Cheap to apply
- Can be used to predict times for work which has not been observed
- Can be used as a basis for price estimating
Normally used where the required time values are not
required in great detail.
- Analytical estimating (combination of estimating & synthesis from standard data)
- Breaks a job into elements;
- Applies any standard or synthetic data that are available
- Carries out measurement on elements
- Estimates any remaining elements using his or her experience & knowledge
- Comparative estimating (identification and measurement of "benchmark" jobs of known work content against which all other jobs to be measured are compared)
