Jon Grunzweig gave a presentation on controlling project costs. He discussed how projects often go over budget and past deadlines due to a lack of accountability and oversight. Grunzweig emphasized the importance of having an accurate project plan, accountable time tracking, and timely status reporting to keep projects on track. He also noted common areas where estimates fall short, such as testing and rework, and stressed measuring success rates to improve estimates over time. The key, according to Grunzweig, is having the right systems and processes in place to monitor costs and catch issues early.
