The increasingly prevalent use of COTS components has attracted a huge capital pool to the industry. The result is an industry that is characterized by strong change forces and weak resistance. Under such environment, weaker players are constantly replaced by stronger players, and older technologies are constantly replaced by emerging technologies. This phenomenon has brought about a new class of risk to the COTS acquirers. These risk factors include the vendor's financial stability and technology capability. However, the existing COTS vendor evaluation taxonomies remain product centric, focusing only on product functionality and costs. We extend the taxonomies to incorporate business factors in the vendor evaluation process, and the resulting process is called VERPRO. The VERPRO decision making tool, which is based on the analytic hierarchy process, allows the acquirers to incorporate vendor business factors into the selection criteria.

The goal of this study is the development of a probabilistic model for the evaluation of flexibility of an object-oriented design. In particular, the model estimates the probability that a certain class of the system gets affected when new functionality is added or when existing functionality is modified. It is obvious that when a system exhibits a large sensitivity to changes, the corresponding design quality is questionable. Useful conclusions can be drawn from this model regarding the comparative evaluation of two or more object-oriented systems or even the assessment of several generations of the same system, in order to determine whether or not good design principles have been applied. The proposed model has been implemented in a Java program that can automatically analyze the class diagram of a given system.

The focus on assessment and measurement represents the main distinction between programming course and software engineering courses in computer curricula. We introduced testing as an essential asset of a programming course. It allows precise measurement of the achievements of the students and allows an objective assessment of the teaching itself. We measured the size and evolution of the programs developed by the students and correlated these metrics with the grades. We plan to collect progressively a large baseline. We compared the productivity and defect density of the program developed by the students during the exam to industrial data and similar academic experiences. We found that the productivity of our students is very high even compared to industrial settings. Our defect density (before rework) is higher than the industrial, which includes rework.

This paper describes a laboratory experiment which evaluates OO-method function points for the Web. OOmFPWeb measures the functional size of Web applications using conceptual models that are developed with object-oriented Web solutions (OOWS), an automated software production method for Web applications. OOmFPWeb is evaluated on a range of performance-based and perception-based variables, including efficiency, reproducibility, perceived ease of use, perceived usefulness and intention to use. The results show that OOmFPWeb is efficient when compared to current industry practices. Furthermore, the method produces consistent functional size assessments and is perceived to be easy to use and useful by its users.

By now, one can point to many instances where measurement has been used effectively to inform management and technical decisions in support of the development and maintenance of software and software intensive systems. Yet, measurement is not very well integrated into software or systems engineering education or practice, and measurement remains challenging for all too many organizations. For this paper, we have analyzed 1350 findings drawn from 663 Software CMM/spl reg/ appraisals that were conducted between 1987 and 2002 inclusive. The results are augmented by questions from a survey of CIO's from state and local governments and the private sector. Our analyses suggest several areas where both managers and engineers would benefit from better guidance about the proper use of measurement and analysis. Future work may include lexical analyses based on natural language processing as well as studies of appraiser understanding of the measurement content in CMMI/spl reg/ models.
