Systematic literature review of machine learning based software development effort estimation models
Context: Software development effort estimation (SDEE) is the process of predicting the effort required to develop a software system. In order to improve estimation accuracy, many researchers have proposed machine learning (ML) based SDEE models (ML models) since 1990s. However, there has been no attempt to analyze the empirical evidence on ML models in a systematic way. Objective: This researc...
Software project management is one of the significant activates in the software development process. Software Development Effort Estimation (SDEE) is a challenging task in the software project management. SDEE is an old activity in computer industry from 1940s and has been reviewed several times. A SDEE model is appropriate if it provides the accuracy and confidence simultaneously before softwa...
Software development effort estimation (SDEE) generally involves leveraging the information about spent in developing similar software past. Most organizations do not have access to sufficient and reliable forms of such data from past projects. As such, existing SDEE methods suffer low usage accuracy. We propose an efficient method for open source software, which provides accurate fast estimate...
Accurate estimating is one of the most important activities in the field of software project management. Different aspects of software projects must be estimated among which time and effort are of significant importance to efficient project planning. Due to complexity of software projects and lack of information at the early stages of project, reliable effort estimation is a challenging issue. ...

one of the most important aspects of software project management is the estimation of cost and time required for running information system. therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. software cost estimation refers to the process of development requirement prediction of software system. various kinds of effort estimation patter...
In the software development process, effort distribution based on phase is an important but often a neglected aspect of software cost estimation. Insufficient phase effort distribution study is the primary reason of poor software effort estimation. This paper provides the results of an empirical study on phase effort distribution based on 2956 projects. The software development process is divid...
OVERWHELMING EVIDENCE DOCUMENTS a tendency toward cost and effort overruns in software projects. On average, this overrun seems to be around 30 percent.1 Furthermore, comparing the estimation accuracy of the 1980s with that reported in more recent surveys suggests that the estimation accuracy hasn’t changed much since then. (The only analyses that suggest a strong improvement in estimation accu...
This paper summarizes estimation knowledge through a review of surveys on software effort estimation. Main findings were that: (1) Most projects (60-80%) encounter effort and/or schedule overruns. The overruns, however, seem to be lower than the overruns reported by some consultancy companies. For example, Standish Group’s ‘Chaos Report’ describes an average cost overrun of 89%, which is much h...
