Purpose – The purpose of this paper is to provide an overview of a pragmatic approach to components off-the-shelf (COTS)-based development. Software product line (SPL) is at the forefront among the techniques for reducing costs, decreasing schedule time, and ensuring commonality of features across a family of products – as COTS are reused in multiple products. Design/methodology/approach – A disciplined process for SPL development is still needed. This paper proposes the Y-model for COTS-based SPL development. The model put forward identifies and elaborates the essential phases and activities of SPL development from COTS-based repository. Findings – The Y-model provides an efficient way of integrating the approaches of SPL and COTS-based development as a cohesive software development model. Practical implications – The model has the potential to tremendously increase software engineers' productivity. Thus, software architects, domain engineers and component designers should become aware of how to use these ideas to structure their models and designs. Originality/value – This paper describes a systematic approach for COTS-based development that takes into account the cataloguing and retrieval of software assets permeating a process that encompasses all stages of software development, from system product requirements engineering to system deployment.

    ABSTRACT: Software product lines and open source software are two emerging paradigms in software engineering. A common theme in both of these paradigms is "reuse". Software product lines are a reuse centered approach that makes use of existing assets to develop new products. At the moment, a motivation for using open source software is so as to gain access to source code, which can then be reused. The product line community is being attracted to open source components. The use of open source software in software product lines is not for one time reuse but, being a core asset, the component is intended to be used repeatedly for the development of other products in the family. In this paper the results of an exploratory study is presented; it was conducted to explore the factors affecting the reusability of open source components. On the basis of the results of the exploratory study a reusability attribute model is presented which makes use of established object oriented metrics accompanied with newly defined metrics. The assessment using the proposed metrics is compared with the rankings assigned by human evaluators.
