Prediction of maintainability using software complexity analysis: An extended FRT

In this paper, a method is proposed for predicting software maintainability. Prediction of maintainability of a product is done by using its code complexity. Here a sample of 4 products is taken into consideration and both the absolute and relative complexity assessment are made over it. The process of measuring the code complexity is done at testing phase. We employ the fuzzy repertory table (FRT) technique to acquire the necessary domain knowledge of testers from which the software complexity analysis is made. Regression analysis is then used to predict maintainability from the product's code complexity.
