Which part of M.O.R.E. is most important for project success?

I would argue that the most important part of M.O.R.E. isn't actually part of M.O.R.E. One way to describe what I mean is "contextual intelligence" - the ability to interpret context and adapt behavior, methods, and decisions accordingly. This changes the original question from "Which part of M.O.R.E. is most important for project success" to "Which capability deficit is currently constraining project success in this organization, and what can actually be influenced from my position?" This may vary across projects and organizations.

Relentlessly Reassess helps organizations remain adaptive under changing conditions.
But reassessment without Expand Perspectives may optimize short-term delivery while missing broader organizational or societal impact.
Reassessment without Manage Perceptions may create technically successful outcomes that stakeholders no longer perceive as valuable.
And without truly Owning Project Success, teams may continue adjusting execution while losing sight of the actual value the project was meant to create.

That is why M.O.R.E. becomes powerful not as a set of isolated practices, but as an integrated way of interpreting success itself:
Success is not only delivered.
It is perceived, sustained, continuously reassessed and connected to wider impact.

I also agree that AI-enabled tools such as PMI Infinity™ can significantly strengthen reassessment cycles by accelerating sensing, analysis and scenario exploration.

But AI can help organizations reassess faster.
It cannot determine which trade-offs preserve long-term value, trust and coherence across stakeholders, strategy and society.

Projects rarely fail because organizations stop reassessing.
They fail when continuous adaptation loses connection with perceived value, shared purpose and systemic impact.
