Use Case Building from Gathered Requirements based on Story Telling Techniques for Design Development

Abstract

During software planning, the duration of time and budget for development are the important factors estimated. When they are not estimated correctly for the software projects, there is a fall in software projects development due to unrealistic estimates. The core reason for fluctuation in the estimation is, thelack of understanding of the requirements properly. These problems have to be assessed at the time of requirements analysis in the requirement engineering phase so that the deflection is not high. Hence the requirement level computing, is often is weighted of a high score. To evaluate each criteria the story telling concept can be used for reducing the deflection of the estimation. In this method, we can understand the stakeholders’ role the requirements which are the base and the business value of each requirement. Hence the analyzing of requirements in view of the stakeholders with regards to the various implementation ways is easier to estimate its need. This research aims to develop a support tool for stakeholders and the requirements engineers to useit in thegathering and analysis of requirements. Implementing the story concept is estimated to reduce the deviations of time and budget plan to near accuracy. The result shows a 75 percentreduction of deviation by using the prediction methods. The prediction method involves Taylors series and exponential methods for evaluation of the requirements to extract the information from the contexts. This method has high accuracy with only about 0.5 percent deviation.
