“…Some good work had been done in the 1960's such as System Development Corp's software productivity data [110] and experimental data showing 26:1 productivity differences among programmers [66]; IBM's data presented in the 1960 NATO report [5]; and early data on distributions of software defects by phase and type. Partly stimulated by the 1973 Datamation article, "Software and its Impact: A Quantitative Assessment" [22], and the Air Force CCIP-85 study on which it was based, more management attention and support was given to quantitative software analysis.…”

“…Estimation of software development effort is an important topic for scholars and practitioners since the 1960s (e.g., [1], [2], [3], [4], [5], [6]). On the one hand, scholars emphasize this importance through their extensive research over the past decades (cf.…”

In most cases, software projects exceed their estimated effort. It is often assumed that inaccurate estimates are the main reason for these overruns. Contrarily, our results show that this assumption is not reasonable in many cases. We conducted a survey to gather data on the current situation of software development effort estimation. Apart from objective criteria, we also asked the participants for their subjective perceptions of the estimates. The participants' perceptions indicate that they do not agree with the objective assessments as 82% perceive their estimate as 'good' despite large overruns and provide reasonable arguments for their perceptions. Furthermore, many projects do not re-estimate the effort due to change requests leading to meaningless comparisons of estimated and actual effort. As a consequence, research needs to find new measures to assess the actual estimation accuracy. Besides the actual estimation process, professionals need to intensify their effort to manage the estimation processes' surroundings.

Estimating the cost of software is a complex process for almost all engineering companies. Uncertainties about development method, design, estimation process, data, and processing affect the accuracy of estimation. Underestimation results in fewer resources being committed than the project really needs, an unrealistic schedule, and low quality outputs.On the other hand, overestimation wastes resources and causes loss of customer credit. Thus, choosing the appropriate cost estimation method is crucial. Studies in the literature emphasize the importance of empirical, analytical methods and expert judgement. Certain cost estimation techniques have been widely studied in the literature. However, there are limited studies using fuzzy approaches for software cost estimation. This paper presents a hesitant fuzzy pairwise comparison (HFPC) used in the hesitant fuzzy analytic hierarchy process for software cost estimation problems by using expert judgement. For this purpose, first a number of criteria are selected with the help of expert judgements from the Turkish banking sector and information technology industry. Subsequently, the HFPC method is presented to estimate the cost of software projects. In order to analyze the efficiency of the proposed approach, it is applied to a software cost estimation problem for a Turkish company. It is seen that the proposed method provides efficient estimations due to low deviation between the real effort and estimated cost. The results are also approved by experts working in the relevant software company.
