In this article, we will learn about:
- empirical estimation techniques
- heuristics estimation techniques
- analytical estimation techniques
Software Project parameters can be estimated using:
- Empirical estimation techniques
- Heuristic estimation techniques
- Analytical estimation techniques
Lets learn about each of them one by one.
Empirical estimation techniques
Empirical estimation techniques is done on the basis of educated guess of the project parameters.
This technique becomes more helpful of the estimator has already had experience doing similar project in past.
Therefore making suitable educated guess, having prior experience and common sense is good element for this technique.
Popularly used empircal project estimation techniques are:
- Expert judgement technique
- Delphi estimation techniques
Heuristic techniques
Heuristic estimation techniques works on assumption that the relationships among various project parameters can be represented in the form suitable mathematical expressions.
Once the basic parameters are known, the other parameters can be determined by substituting value of basic parameter in mathematical expression.
It can be widely divided into two classes
- Single variable model
- Multivariable model
Popularly used heuristic estimation techniques are:
Analytical estimation techniques
Analytical estimation techniques derive the required results starting with certain basic assumptions regarding the project.
Popularly used analytical estimation techniques are:
- Halstead software science
