This project, a student's portfolio for the PPMP20011 unit, focuses on commercial negotiation, conflict management, and stakeholder engagement across various project contexts. It differentiates project negotiation methods, including proper listening, building rapport, and emotional attachment, and explores methods for maintaining stakeholder relationships, such as openness and building rapport. The portfolio also examines the consequences of project delays, disruptions, and changes, along with methods for handling claims and variations, and identifies project management tools like Lean, Agile, and Six Sigma. Furthermore, the assignment includes reflections on the role of project managers in commercial negotiation, the impact of project management standards and frameworks, and the spectrum of contractual arrangements. It also delves into the application of logic, persuasion, and influence in arguments within negotiation, and discusses communication strategies in commercial settings, conflict resolution, and the influence of trust and collaboration. The student references various sources, including academic journals and project management standards, to support their analysis and reflections.
