This paper summarizes the results of a study on fifteen projects that used a COTS-based approach. The process they followed is evaluated to identify essential differences in comparison to traditional software development. The main differences, and the activities for which projects require more guidance, are requirements definition and COTS selection, high level design, integration and testing.

The work described in this paper is an investigation of COTS-based software development within a particular NASA environment, with an emphasis on the processes used. Fifteen projects using a COTS-based approach were studied and their actual process was documented. This process is evaluated to identify essential differences in comparison to traditional software development. The main differences, and the activities for which projects require more guidance, are requirements definition and COTS selection, high level design, integration and testing.

We present a descriptive and exploratory study of factors that can affect the success of COTS-based systems. Based on a review of the literature and industrial experience, the choice of life cycle model and the amount of glueware required were hypothesized as the main factors in predicting project success. In this study we examined the relationship between different life cycle models and COTS integration project success. Two life cycle models were studied: the sequential model and the iterative model. Seven subjects from six industrial organizations responded to a survey providing data on 23 COTS integration projects. While there was variability between iterative and sequential projects on a variety of organizational and product factors, little difference was found between the life cycle models on the success criteria of projects (i.e. being on time, meeting requirements and being within budget). We found that projects that met two or three of the success criteria had significantly higher scores on project characteristics (organizational plus product) than those meeting none or just one.

Selecting COTS products is a process that inherently involves tradeoffs. In this position paper, we highlight the challenges of the requirements process for COTS-based system where the negotiation of requirements plays a critical task. In particular, it is necessary to perform a careful balancing between stakeholders requirements and COTS features. We analyse the processes of COTS matching and balancing using a goal-driven approach.

"International Workshop on Models and Processes for the Evaluation of COTS Components (MPEC 2004)" W7S Workshop - 26th International Conference on Software Engineering, 2004

The use of Commercial-Off-The-Shelf (COTS) software has become more and more important in software development. In COTS-based development, COTS component selection is the most crucial phase. Although some selection processes have been proposed, empirical studies are necessary to assess these processes. This paper describes an exploratory study by structured interviews of 16 COTS-based development projects in Norwegian IT companies. The results indicate that successful COTS component selection can be implemented without using formal processes, and projects with different contexts may use different selection processes. If members in new project has enough practical experience with actual COTS components, such experience can be the dominant factor in selection. In the case of using a new COTS component in the project, hands-on experimentation is needed as an effective way of evaluating the component.
