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...
This paper presents a comprehensive overview of the state of the art in software resource estimation. We describe common estimation methods and also provide an evaluation framework to systematically compare and assess alternative estimation methods. Though we have tried to be as precise and objective as possible, it is inevitable that such a comparison exercise be somewhat subjective. We howeve...
In this paper we study the effects of a change from the traditional request “How much effort is required to complete X?” to the alternative “How much can be completed in Y workhours?”. Studies 1 and 2 report that software professionals receiving the alternative format provided much lower, and presumably more optimistic, effort estimates of the same software development work than those receiving...
Context: Software development effort estimates are often inaccurate, and this inaccuracy cause problems for the clients as well as the providers. Consequently, we need more knowledge about the estimation processes, so that we can improve them. Objective: This study investigates how initial judgment-based estimation of work effort in software development affects subsequent, unrelated estimation ...
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...
The paper gives an overview of the state o f the art o f software cost estimation (SCE). The main questions to be answered in the paper are: (I) What are the reasons for overruns o f budgets and planned durations? (2) What are the prerequisites for estimating? (3) How can software development effort be estimated? (4) What can software project management expect from SCE models, how accurate are ...
Software cost estimation is the process of predicting the effort required to develop a software system. Many estimation models have been proposed over the last 30 years. This paper provides a general overview of software cost estimation methods including the recent advances in the field. As a number of these models rely on a software size estimate as input, we first provide an overview of commo...
in this paper an efficient three- stage algorithm is developed for software production cost and time estimation. first stage includes a hybrid model composed of cocomo and function points methods to increase estimation accuracy. second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...
