This assignment is a weekly portfolio for the PPMP20011 course, focusing on Week 3's topic: The Role of the Project Manager in Commercial Negotiation. Students are required to reflect on readings, particularly 'Collaborative Project Procurement Arrangements' by Walker & Walker (2015), and apply concepts to real-world scenarios like the Chunnel Project. They must analyze negotiation methods, conflict management, stakeholder engagement, and the consequences of project delays and disruptions. Furthermore, students are expected to evaluate tools that facilitate conflict resolution through negotiated solutions.
