By Reiner Dumke

Designed to comply to the ISO/IEC ordinary 14143, the typical software program size foreign Consortium (COSMIC) functionality element technique has develop into the foremost estimation procedure according to foreign criteria for development software-intensive structures. COSMIC functionality issues: thought and complicated Practices provides a state of the art examine present and rising practices within the overseas software program dimension neighborhood. The editors have assembled a global panel of specialists who element the stairs for measuring the sensible measurement of software program and constructing undertaking estimates with more advantageous accuracy. They clarify how you can evaluation and examine structures to enhance software program reuse and improvement. relating the basic elements of the subsequent iteration of useful measurement size tools, the publication delineates most sensible estimation and dimension practices in addition to the advance of benchmarks for caliber development, together with Six Sigma. this entire source covers software program size and estimation equipment and practices for embedded structures, enterprise purposes, communications software program, and keep watch over platforms. every one bankruptcy provides the sensible figuring out required to create, enforce, standardize, distribute, and adapt sensible measurement size and undertaking estimation to almost any software program context. compliment for:… a superb review … offers a robust wisdom heritage for either practitioners and researchers. … With its extensive historical past, it's necessary for essentially imposing and effectively adapting different useful sizing equipment … . The COSMIC functionality aspect innovations provided during this booklet may also help you to enforce, grasp, and increase your estimation process.—Christof Ebert, dealing with Director, Vector Consulting prone

5 Inclusion of Reuse Functional size measurement traditionally measures the entire functional size of a software product from the user’s perspective. , object orientation, COTS, and JavaBeans, for the determination of the selfdeveloped part of the software for business calculation, this measurement is not enough anymore (detailed information can be found in Dumke et al. (1999)). © 2011 by Taylor & Francis Group, LLC 36 ◾ COSMIC Function Points: Theory and Advanced Practices Meli (1997a) identifies that it becomes necessary to distinguish between function points asked for and released to the user and function points actually developed by the software team.

Software engineering—COSMIC-FFP—A functional size measurement method. ISO/IEC 19761:2003. , states and transitions), and this makes it more difficult to count earlier. Thus, it must be measured later in the software life cycle than Mark II function points, feature points, and IFPUG function points, which can be measured at the same time with the same level of detail and with the same precision as function points. Unfortunately, this required level of detail is only available after 15 to 40% of development time.

But some problems remain. Of course, with the help of most of the functional size methods, each functional domain can be measured and a value is derived. Then the question is whether this value is the correct representation of a system or just a number without any meaning. Symons (1999) recognized that one of the difficulties is that the method definition and procedures become increasingly complex, because new rules have been added continuously in order to cope with interpreting an old sizing method in terms of new development methods and technologies.
