Here is what works: 1. Maintain a To Do list for the project. 2. When a developer is available, he/she/it will pick the highest priority task to work on. 3. Use the To Do list when negotiating new features with stake holders. They have to decide where in the priority list the new task is added. 4. Break very large tasks into smaller step by step tasks that can be developed independently. It’s simple. It works. I have delivered successful projects most of my career using that method. As a single developer and when managing large teams of developers.
