Framework for Developing a Software Cost Estimation Model for Software Modification Based on a Relational Matrix of Project Profile and Software Cost Using an Analogy Estimation Method

Abstract

Software cost estimation is one of the most challenging works due to the fact that it requires detailed information about each stage of the project, including the project scope, project requirements, software development methodology and the required resources. Often, this information is not known until the final stage of project while the cost of project needs to be estimated at the initial stage. There are many different ways to estimate software costs and each way has its own characteristics and purpose according to each project profile. The purpose of this research is to propose a framework for developing a software cost estimation model for software modification project based on a relational matrix of a project profile and software cost using an analogy estimation method and multiple regression analysis to estimate the amount of software modification list and the amount of effort need for the new project from the data collection of the previous project.

A Survey on Software Cost Estimation Techniques

“…The analogy was used in the past as a method of supporting or supporting explanations of a particular natural phenomenon which was later incorporated in the software development sector of software development of for the purposes of software cost estimations [36]. Analogy Based is one of the most efficient approaches in software cost estimation due to its outstanding performance and capability of handling complex datasets [37]. The model exploits comparison as the main form of a subject to compare software project under considerations with past historical projects which have prior known characteristics, schedule and efforts.…”

“…The model exploits comparison as the main form of a subject to compare software project under considerations with past historical projects which have prior known characteristics, schedule and efforts. Thus, this model has to rely on previous projects similar to the ones that are to be developed thus the levels of accuracy are usually very high [37].…”

Predicting Software Damage Rate from Cognitive Bias in Software Design Process

“…The various types of biases may effect on software development. There were four types of bias; anchoring, adjustment, availability, and confirmation; usually occur in software engineering aspect [3].Thus, these four biases were selected to study in our research.An analyzed the independent variables with the dependent variable by using multiple regressions and correlation analysis to find factors might affect the cost of software customization [8].We would like to apply the same statistical method to our research. They have proven that there were three types of bias might occur during requirement gathering and specification process and there were a strong collinearity between anchoring bias and adjustment bias [11].…”
