Make crisper, more comprehensive decisions about proposed and ongoing projects in your portfolio with this online course.

This course will prepare you to undertake the kind of thoughtful, quantitative analysis that will guide you through development stages. You’ll learn how to avoid two undesirable outcomes as your projects progress through increasingly costly stages—investing in further development when a positive outcome is unlikely and dropping a project too early that would have significant benefit if successful. You’ll address how to uncover the value proposition, perform heat and material balance calculations and make process design considerations. You’ll also examine how to develop operating costs and margin calculations, size equipment, estimate capital and calculate metrics, such as NPV and IRR from cash flows.  By taking part in example problems, you’ll see how to frame the value proposition, work through the mechanics of determining operating and capital costs and calculate economic metrics. In addition, sensitivity analyses will illustrate how to easily uncover and communicate leveraging issues.
