This webinar discusses the Lean Startup methodology for project management. The Lean Startup approach emphasizes validating business ideas with customers early through minimum viable products and experiments, rather than relying on business plans. It outlines key Lean Startup principles like the customer feedback loop, where assumptions are tested through small experiments and iterations based on learnings. Three essential Lean Startup tools - the business model canvas, assumption mapping, and customer feedback loop - are presented as ways to systematically test risks and learn through customer interactions whether to pivot or move forward with an idea. The webinar contrasts the Lean Startup approach which starts with unknown problems and solutions with traditional waterfall and agile development models.
