Many people view an estimate as a quick guess that no one believes anyhow. But producing a viable estimate is core to project success as well as ROI determination and other decision making. In decades of studying the art and science of estimating it has become apparent that: most people don't like to and/or don't know how to estimate, those that estimate are often always wildly optimistic, full of...
This paper presents a new forecasting model to ensure project success. This new model is based on improvement on earned value (EV) method. This model improves earned value management system (EVMS) and forecasting time and cost for projects. These method use established consists of four variables: scheduled performance index (SPI), cost performance index (CPI), cost variance (CV), schedule variance...
This paper presents an implementation and evaluation of Earned Value (EV) method of projects to improve earned value management system (EVMS) and forecasting time and cost for projects. These method use established consists of four variables: Scheduled Performance Index (SPI), Cost Performance Index (CPI), Cost Variance (CV), Schedule Variance (SV). The model has been validated by a simulation study...
