Ineffective COTS implementation will cost you Adopting commercial off-the-shelf (COTS) products or packages like ERP, CRM, and HR management systems to fulfil a range of enterprise functions is a crucial decision involving huge investment. Most implementations do not identify testing as an independent function required during the implementation of the COTS product, while others do not engage te...

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,...

The DEAR-COTS (Distributed Embedded ARchitecture using Commercial Off-The-Shelf components) architecture provides a COTS-based framework to execute reliable hard real-time applications. To ease the task of building reliable realtime applications on top of COTS components, a simple and transparent programming model is provided, in order that programmers abstract from the low-level implementation...

This paper reports on experiences of generating COTS components when designing and deploying component based software architecture for automation and interoperation of medicinal product evaluations across different countries in the world. Our generic architectural model renders two sets of software components that are candidates for COTS components. We identify which role such COTS components m...

As government technical teams downsize and budgets shrink in tandem with an increasing demand for more complex systems, there is a rising interest in leveraging the use of commercial-off-the-shelf (COTS) products. In many cases, the use of COTS is mandated. Is it possible to over-emphasize the use of COTS products? For example, what checks would you expect prior to flying on a new aircraft with...

The process of developing software applications by integrating one or more Commercial Off-The-Shelf (COTS) components has received much attention lately because it provides potential benefits including shortening the development time, reducing effort and shrinking budgets as well as improving the quality of the final product. However, COTS-based development (hereafter CBD) in particular the eva...

Resumen El uso de modelos de calidad durante la selección de componentes COTS (Comercial, Off-The-Shelf components) proporciona un entorno adecuado para la descripción de los dominios a los que pertenecen dichos componentes. La selección en este caso resulta más eficiente y fiable, pues tanto las descripciones de los componentes COTS como las de los requisitos de calidad de los usuarios pueden ...

The chiral optical Tamm state (COTS) is a special localized state at the interface of a handedness-preserving mirror and a structurally chiral medium such as a cholesteric liquid crystal or a chiral sculptured thin film. The spectral behavior of COTS, observed as reflection resonances, is described by the temporal coupled-mode theory. Mode coupling is different for two circular light polarizati...

Some of the most significant changes that have confronted DoD software acquisition efforts in the past few years are the result of using Commercial OffThe-Shelf (COTS) software. However, these changes are not unique to the DoD—virtually all segments of US Government and industry have been forced to deal with the implications of COTS software. These changes are the inevitable and irreversible co...

The goal of the GUARDS project is to design and develop a generic fault-tolerant computer architecture that can be built from predefined standardised components. The architecture favours the use of commercial off-the-shelf (COTS) hardware and software components. However, the assessment and selection of COTS components is a non-trivial task as it requires balancing a myriad of requirements from...
