Project Management Course - Beginner to Project Manager Smart Home Project Case Study: How Changing Requirements Impact Time, Cost, and Success In this case study, Bill’s smart home project shows how quickly a clear plan can become complex when requirements keep changing during execution. What started as a simple idea—adding convenience and smart control to a home—evolved through multiple adjustments, including parental controls, air-conditioning integration, and even a voice-controlled assistant. Each change improved the product in some way, but also introduced delays, extra costs, and rework. By the end of the project, the team successfully delivered a working solution, but not without inefficiencies and frustration due to late-stage requirement changes. The key lesson is clear: even when changes are valuable, introducing them late in the project can significantly impact time, budget, and team productivity. Proper planning, clear initial requirements, and controlled change management are essential to avoid these challenges. In the next lesson, we’ll explore why this type of project behavior challenges traditional waterfall project management and what alternatives might work better.
