“…On the other hand, the previous studies (the first six rows of Table I) were also characterized by a coefficient around 1 but with a most probable interval of (1.1 -1.2). As for R 2 , Table II suggests that a high value was obtained in all the studies (except for the first case study in [7]). …”

“…Few case studies have been conducted to identify conversation equations between FPA and COSMIC and the most relevant are summarized and discussed in [7]. In particular, Cuadrado-Gallego et al performed a review of previous investigations that mainly exploited linear regression analysis to identify a sound mathematical basis for converting FPA measurement in COSMIC measurement, i.e., by constructing an equation as:…”

“…About, 2nd generation methods, and in particular COSMIC, the preliminary studies conducted with Web applications seem to highlight interesting results (see e.g., [9][10]). Nevertheless, many companies have employed for years IFPUG Function Points Analysis (FPA) and have their IFPUG-based historical data for estimating and planning their software projects [7]. As a consequence, even if they could be interested in applying COSMIC they are prevented to this due to the additional effort and costs.…”

“…In order to facilitate this migration, some researchers have proposed to exploit in the first phase of this process the size estimates available in terms of FPA to automatically obtain the size estimates in terms of COSMIC. To this aim, some studies have been carried out to identify conversion equations [1] [7][8] [11] [14]. Following this research direction, we have performed a case study on 25 Web applications of an Italian software company in order to verify whether it is possible to obtain accurate size estimates in terms of COSMIC exploiting the available information on the size in terms of FPA.…”

Abstract-Some empirical studies have been carried out so far to identify a function able to convert IFPUG functional size units to the COSMIC ones. In this paper, we report on a replication of those studies using a dataset of 25 Web applications. As for the estimation technique, we employed linear regression analysis; while k-fold cross validation was exploited to validate the estimation models. The results show that there is a significant correlation between the size expressed in terms of COSMIC and IFPUG, but differently from previous studies the conversion factor is not so close to 1.

“…Data from 25 web projects were used to validate the results and it was reported that COSMIC was significantly more accurate than FP in estimating efforts when SLR & CBR were estimation models. This study further advocated Two step estimation process (2SEP) to carry out migration from FP to COSMIC by using conversation equation, and selection of equation had influenced the efforts [55] [56].…”

In present era of information technology web applications have become an indispensable and most pivotal source to disseminate information across geographically distant nodes. Most of the organisation public or private have switched their existence from traditional software based systems to web based software systems. Many characteristic differences between traditional software and web based software application made web based existence more popular with wide range adoption. The sudden surge in web application usability across different organisation have posed a grave challenge for web development companies to deliver their products onetime and within budget with much expected accurately, efficiency and reliability. Effort estimation is main domain that decides the budgetary constraints associated with web application development. Accurate estimates are very essential for both developer and client. Accurate estimates make web development companies to maintain their reputation, competitive edge and client base. Inaccuracy in effort estimates results to lose revenue, client base and competitive strength. Effort estimation is very import for every development organisation to estimate the development work in early stages of development to prove efficient, accurate and much reliable budget estimates. This paper is an effort to explore various effort estimation techniques for web development, their challenges and measures to predict accurate efforts.
