Pulse of the Profession 2026: Why a Third of Complex Projects Fail Despite Best Practices

The Project Management Institute released its annual Pulse of the Profession report in May 2026. Its finding: complexity is now the baseline, not the exception, and traditional delivery methods no longer contain it on their own. For programme leaders and PMOs, the message is about fundamentals, not a new tool to adopt.

Nearly every professional is affected

97% of project professionals managed at least one complex project in the past year, according to PMI. 81% report increased project complexity, with 37% describing the increase as “significant.” Business leaders point to AI and automation as the top driver of operating-model change (cited by 72% of executives), followed by faster technology cycles (cited by 48% of project professionals).

The consequence is measurable: nearly a third (31%) of complex projects fail to deliver their intended benefits, versus 13% across all projects regardless of complexity. The failure rate more than doubles once complexity sets in.

The best-practices paradox

PMI’s data shows that organisations following recognised frameworks do not automatically perform better. What separates high performers is how they handle complexity itself, more than compliance with a given methodology.

The gap between effective and ineffective complexity management (74 points) dwarfs the gap tied to using a framework (11 points) or to having a PMO (6 points). A methodology helps; it does not replace a team’s ability to read a shifting system and adjust course.

M.O.R.E.: four levers, 7% full adoption

PMI links this finding to its M.O.R.E. project success model, introduced in late 2025 in its Step Up report: Manage perceptions (shaping how stakeholders understand project value), Own success (taking accountability for outcomes), Relentlessly reassess (continuously re-evaluating the path forward), and Expand perspective (accounting for broader organisational and sustainability impacts).

Pulse 2026 confirms that professionals applying this vision are three times more likely to deliver a successful outcome. The original Step Up research had already quantified the gap: only 7% of professionals apply all four levers at once, but those who do reach a Net Project Success Score of 94%, well above the baseline for everyone else. PMI’s point is not to add another process, but to strengthen a project team’s judgment and its capacity for continuous adjustment — a shift from “managing tasks” to “managing systems.”

Regulatory watch

On 23 September 2026, ESMA created a new Union Strategic Supervisory Priority (USSP) on digital innovation: from 2027, it will cover how supervised entities use artificial intelligence and tokenisation. The same day, the EU’s three supervisory authorities flagged external dependencies, cyber threats and private credit as key vulnerabilities in their autumn 2026 risk assessment. On 25 September 2026, the EBA opened a consultation on revised technical standards governing joint decisions on institution-specific capital and liquidity requirements.

What this means for you

1. Measure your projects’ perceived complexity at framing stage, not after the first signs of drift: this indicator correlates more strongly with success than adherence to any single framework.
2. Formalise sponsor alignment at initiation and build in regular reassessment checkpoints, rather than relying on a single end-of-phase review.
3. Assess your PMO’s maturity on its ability to surface weak signals early, not only to consolidate progress indicators.
