Introduction What is software measurement? GQM technique

We use software measures to derive A basis for estimates, A basis for estimates, To track project progress, To track project progress, To determine (relative) complexity, To determine (relative) complexity, To help us to understand when we have achieved a desired state of quality, To help us to understand when we have achieved a desired state of quality, To analyze To analyze To experimentally validate best practices To experimentally validate best practices

Goals of software measurement To predict the error-proneness of a system using software measures from its design phase. To extract quantitative features from the representation of a software design to enable us to predict the degree of maintainability of a software system. To extract quantifiable features from the representation of a software design to enable us to predict the amount of effort required to build the software described by that design.

Measurement Process and Different Models High Level Model High Level Model Detailed Model Detailed Model

HIGH LEVEL MODEL 1 First we should measure and design the measurement method 2The rules of the measurement method are applied to a software or piece of software 3The applications of the measurement method rules produce a result. 4 The measurement result is exploited in a quantitative or qualitative model.

High Level Model Design Application Analysis Exploitation

Detailed Model Design of Measurement method Design of Meta Model Concept to be measured Definition of numerical assignment rules

Detailed Model Definition Of objectives Concept to Be Measured Meta Model Numerical Assignment Rules

Validation Requirements Validation Frame Work

Conclusion Measurement is must for any product to become famous Output of measurement method will be context based Depends on how well the user analyses and uses the terms
