The document discusses the seven deadly sins of enterprise software development and provides advice for overcoming challenges with digital transformation projects. It argues that accurately forecasting the future is impossible when a project involves both complexity and uncertainty. Traditional project management approaches assume one can perfectly predict outcomes, but complexity grows exponentially as more tasks and variables are added. The ability to forecast success decays rapidly as a result. Additionally, customer adoption depends on perceived value, work required, and willingness to change - which are also difficult to predict accurately. Ultimately, the document advises that any complexity or unknowns drives the ability to forecast a project's scope and timeline close to zero.
