A presentation divided into eight parts on the 'humble project management toolkit' - a set of tools which helps us to effectively manage projects in the face of uncertainty. In these presentations I describe the 'Planning Fallacy'- why projects always go over budget, over time, and fail to deliver to specification. I introduce two of the main causes of the Planning Fallacy: our cognitive biases or 'thinking errors' and complexity. I outline the 'humble project management toolkit,' describing some of the many approaches to project planning, implementation, and monitoring and evaluation that are stored in the toolkit's six 'compartments': 1. Hesitate to encourage reflection; 2. Understand the project's ecosystem; 3. Manage in alignment with the project's ecosystem; 4. Bring in diverse perspectives; 5. Learn constantly; and 6. Embrace uncertainty
