explain to new project management students what earned value management is. Base this presentation on a simple project to construct a new shed on a rectangular block of land for your friend. Your friend lives on a large rural bush block in Western Australia. Assume that the materials are all on-site, that your friend will build the shed, and that all necessary permits and permissions have been obtained. Ensure you discuss schedule variance (SV), cost variance (CV), schedule performance index (SPI), cost performance index (CPI) and the four forecasting techniques estimate at completion (EAC), estimate to complete (ETC), variance at completion (VAC), and to complete performance index (TCPI)
