Role of Tailorability to Access Software Product Line Orthogonal Variability Model Maintainability

Abstract

Software product line is defined as a set of similar software systems that sharejoint and managed set of features to satisfy the specific need of a particular market segment and these are developed from core assets in a prescribedway¹. All the systems that come in product line have commonalities and variability. Anincreasing trend in software development is the requirement to develop new multiple and similar products at same time instead of single individual product. There may be quite a lot of reasons behind this. For continue the function of any product and developit as needed, it is important to look upon all the quality attributes that may affect it in future. There can be two types of quality attributes: internal and external. We can directly measure the internal quality attributes on the basis of product features such as size, length or complexity. Whereas there are external attributes like efficiency, reliability and maintainability. The maintainability which can be measuredrelating to how software relates with its environment and consequently, can be measured one time the software systems fully developed and deployed. Maintainability is one of these external quality attributes that is much valued at the present time. Maintainability is according to ISO/IEC 9126 standard means “the capability of software product to be modified.In current research we predict how the tailorability will predict OVM product line maintainability by using of developed metrics.
