Looking at the distribution of the costs of IT, the largest part of the budget is allocated to maintenance and enhancement projects. New development comprises between 30 to 50% of IT costs. Functional size measurement methods are mostly used for new development only. With some extensions to common size measurement methods like Function Point Analysis and COSMIC Full Function Point one can tackl...

Software size is the fundamental metric for project planning. Effort and duration are calculated based on the size estimate. However, for a given software size, the actual development effort could be significantly different. The question is whether the increase in effort is due to the low productivity of the development team or higher product quality. While higher product quality is highly desi...

The measurement of the functional size of applications generated in MDA environments is a challenge for the software development industry. This paper presents the OO-Method COSMIC Function Points (OOmCFP), a measurement procedure that has been designed to measure the functional size of object-oriented applications generated from their conceptual models by means of model transformations.

We present an extended paradigm for sizing and fit, mass customized target market sizing; that is, sizing systems based on and derived from measurement data exclusively from the people who represent an apparel firm’s target market. Mass customized target market sizing is proposed as an alternative to proportional sizing systems used by the apparel industry for ready-to-wear. Advancing technolog...

Functional Size Measurement methods –like the COSMIC method– are widely used but have two major shortcomings: they require a complete and detailed knowledge of user requirements and they are carried out via relatively expensive and lengthy processes. To tackle these issues, simplified measurement processes have been proposed that can be applied to requirements specifications even if they are in...

We study the following lot-sizing models that recently appeared in the literature: a lotsizing model with a remanufacturing option, a lot-sizing model with production time windows, and a lot-sizing model with cumulative capacities. We show the equivalence of these models with a classical model: the lot-sizing model with inventory bounds.

This paper reports an empirical study that used computer science major students as experimental subjects to evaluate the productivity and the reproducibility of RmFFP. This is a functional size measurement procedure designed according to the COSMIC-FFP method for object-oriented systems that are specified using the OO-Method approach. The results show that the productivity of RmFFP is acceptabl...

SOA (Service Oriented Architecture) is a loosely-coupled architecture designed to tackle the problem of Business/Infrastructure alignment to meet the needs of an organization. A SOA based platform enables the enterprises to develop applications in the form of independent services. To provide scalable service interactions, there is a need to maintain service’s performance and have a good sizing ...

A meta-analysis assessing the relationship between software size and software quality across 10 diverse software project studies spanning over 20 years suggests that the relationship between software size and quality is strong and significant. However, the analysis of several moderating variables indicates that technology, process and resource factors also help explain the variance in software ...

Many functional size measurement procedures have been developed for applying the COSMIC measurement method to particular methods of software production. A subset of these measurement procedures is centered on the measurement of the functional size of the applications from their conceptual models, allowing the generation of indicators in early stages of the development cycle of a software produc...
