TL;DR: Analysis of data gathered on a major system over a period of 18 months suggests that the size of the component to be changed has a much larger impact on effort than thesize of the change itself.

Abstract: Function point analysis (FPA) is a well-known method to measure the functionality of a system, from the user's point of view Both Albrecht's (1979) original model and a local variant we studied assume that effort is primarily related to the size of a change Analysis of data gathered on a major system over a period of 18 months does not confirm this relation Rather our data suggests that the size of the component to be changed has a much larger impact on effort than the size of the change itself Furthermore, the various corrective factors of the function point model do not help to improve effort estimates in the environment we studied Finally, we found that expert estimates outperform the function point estimates, while analogy-based estimates slightly outperform the expert estimates

A review of studies on expert estimation of software development effort
TL;DR: An extensive review of studies related to expert estimation of software development effort suggests that expert estimation is the most frequently applied estimation strategy for software projects, that there is no substantial evidence in favour of use of estimation models, and that there are situations where the authors can expect expert estimates to be more accurate than formal estimation models.

Forecasting of software development work effort: Evidence on expert judgement and formal models
TL;DR: The review found that the average accuracy of expert judgement-based effort estimates was higher than theaverage accuracy of the models in ten of the sixteen studies, and two indicators of higher accuracy were estimation models not calibrated to the organization using the model, and important contextual information possessed by the experts not included in the formal estimation models.

TL;DR: It is proposed that it may be possible to use a combination of tools to perform the analysis process providing that adequate means of efficiently identifying false matches is found.
Estimating software project effort by analogy based on linguistic values

TL;DR: A new approach based on reasoning by analogy, fuzzy logic and linguistic quantifiers to estimate software project effort when it is described either by numerical or linguistic values is proposed; this approach is referred to as Fuzzy Analogy.

TL;DR: In this paper, the equivalence between Albrecht's external input/output data flow representative of a program (the function points" metric) and Halstead's [2] "software science" or "software linguistics" model of a programming program as well as the "soft content" variation of Halsteads model suggested by Gaffney [7] was demonstrated.

An empirical validation of software cost estimation models
TL;DR: Four of the most popular algorithmic models used to estimate software costs (SLIM, COCOMO, Function Points, and ESTIMACS) are evaluated, finding that all of the models tested failed to sufficiently reflect the underlying factors affecting productivity.
