2642 for a hypothetical gold processing facility demonstrate the significant impact of extended production rampup times. The McNulty curves serve as a powerful tool to assist project owners in building trust for the business case to support transformation and de-risk new technology to enable more successful ramp-ups. It is important to have the right team with phronesis and to design for successful delivery to set today’s project owners up for success in delivering the minerals the world urgently needs, faster, smarter, and more responsibly. Project owners can achieve successful ramp-up performance by being mindful of the dominant factors of success and failure, i.e., quality of underlying information, development of the necessary process design criteria, providing the experience and sustained commitment of the owner's project team, and avoiding commitment to unrealistic fast-track schedules that could undermine previous project plans and suppress managed decision making. The McNulty Curves serve as an empirically based planning tool to facilitate mature and active derisking of projects. ACKNOWLEDGEMENTS We would like to acknowledge the contributions from John Bryant, Mike Fedoroff, Kerry Hill, Isabelle Plante, James Nguyen, Melfi Villanueva, and Nils Voermann. We would also like to give special acknowledgement to Professor Bent Flyvbjerg’s reference to Aristotle’s description of practical wisdom as “phronesis” to show how it enables teams to deliver successful capital projects [8].
