This session offers a deep dive into one of the four core values in PMI’s Code of Ethics and Professional Conduct. It explores what Responsibility means for project professionals in practice, how it guides decision‑making under pressure, and how alleged breaches are considered within PMI’s Ethics Review Committee (ERC) framework. To bring these concepts to life, the presentation introduces a fictitious case study. The scenario illustrates potential breaches of Responsibility, how these choices erode trust, expose the organization to harm, and contradict PMI’s expectations for ethical behavior. Using this case, the presentation then walks through how such a situation might be viewed within the PMI Ethics Review Committee framework describing the range of potential actions the ERC may consider when a breach of Responsibility is substantiated, The presentation concludes by directing participants to PMI’s official ethics resources on pmi.org, including the PMI Code of Ethics and Professional Conduct, ethics complaint and review process information, and case‑based learning materials, underscoring that Responsibility is a daily practice central to professional credibility and long‑term success in project management.
