|Pricing is one of the key element in software purchase it is as important among the 4 P’s of Marketing Mix. The estimation of product cost, is directly related to $ P’s of marketing, its become more critical task in the case of project management of ERP software. The criticalness of this task goes tough and tough as the complexity of software projects increases, at the same time the cost associated with the projects is also increases. Therefore it is advised to determine the software price the estimation should be done in the early stage of development . However, as regards the issue of customer satisfaction, end-users are often unsatisfied with software project management results
Another key task is to suggest or develop the useful model which demonstrate the development stages of software life cycle with E-R diagram . The basic life cycle of softwares the Currently used software development effort estimation models such as, COCOMO and Function Point Analysis, do not consistently provide accurate project cost and effort estimates. This is often because important project data, available at the time of modeling, are often vague, imprecise, and incomplete. Traditionally used cost estimation models cannot utilize such vague yet important information in their models.
At present few models are being adopted in the industry like fuzzy logic, COCOMO and function point analysis. Due to the various parameters these models are also not able to provide the pricing solution like imprecise and incomplete vague data Fuzzy logic method is suitable up to some extent in case of vague data… due to this reason the emergence of result based ERP software pricing is emerging, which can transform the whole software industry, few considerations for this idea is discussed in this context.
