VRS Model: A Model for Estimation of Efforts and Time Duration in Development of IVR Software System

Accurate software effort estimates are critical to measure for developers, leaders, project managers. Underestimating the costs may result in management approving proposed systems which can exceed their budgets,with underdeveloped functions and poor quality, and failure to complete on time. Various models have been derived to calculate the effort of large number of completed software projects from various organizations and applications to explore how project sizes mapped into project effort. But, still there is a need to prediction accuracy of the models. Day to day there is rapidchange and growth to get new techniques and model to estimate the accurate size, effort and cost of software but still there is lack of accuracy to meet exactly the accurate effort as per company norms and standards. A BPO Company takes up a process of another company. The Company which is handling the incoming calls of customers, queries, solution, services through software is known as IVR software.In this paper the author has proposed a model named “VRS Model” toestimate the accurate effort and schedule of IVR software applications. This model will be helpful for project managers, developers and customers to estimate accurate effort and schedule of only IVR Projects.
