Verification & Validation of components with new X Component-Based Model

Software Verification and Validation (V & V) activities check the software against its specifications. Every project must verify and validate the software. This is done by checking that software meets specified requirements by ensuring that the amount of V & V effort is adequate to show each software item is suitable for operational use. In the era of Software Engineering (SE), Component-Based Software Development (CBSD) put new demands on how to ensure the needed functionality and quality of the software with, V & V. In traditional software, V & V could be done in close cooperation with the customer to meet the specific requirements from the customer. When developing software components, or Component-Based Software Systems (CBSS), V & V becomes a bit more complicated. Components developed for reuse, and especially components developed for the open market, have to be more thoroughly specified and verified then most custom software for many reasons. This paper present V & V when developing software components which are helpful in improving the functionality and quality of component and Component-Based System (CBS) by using a new X Component-Based Model.
