Making difficult missions possible through resilience and critical thinking

Uncertainty is perhaps the only thing certain in our world. Project professionals cannot remove it, but they can become better at working through it. Geopolitical instability, conflict, economic disruption, climate risks and rapid advances in Artificial Intelligence (AI) mean decisions increasingly have to be made with incomplete or changing information.

Resilience and critical thinking are therefore more important than ever. Resilience enables people to absorb setbacks, learn and continue; critical thinking helps them decide when persistence is useful and when the evidence requires a change of direction. Together, they help project leaders turn missions that may initially appear impossible into possible ones.

Resilience shaped by lived experience

My understanding of resilience began before I became a project professional. My grandparents lived through the Second World War and my parents grew up in the post-war period. I was raised on stories of uncertainty, adapting to circumstances beyond their control, appreciating what they had and continuing when life did not follow the expected path.

We should not romanticise hardship, and resilience is not about pretending that difficulty does not hurt. I learned that setbacks and uncertainty are part of life. We may lose an opportunity, make a mistake or work hard without achieving the outcome we wanted. What matters is whether we learn, recover and find another route.

Those lessons became relevant throughout my career. Projects rarely unfold exactly as planned: funding changes, suppliers fail, priorities move and unanticipated risks emerge. Resilience helps us continue; critical thinking stops determination becoming persistence in the wrong direction.

1. Build tolerance for uncertainty

People often reach for a quick answer because uncertainty is uncomfortable. Strong project leaders resist false certainty. They make the best proportionate decision available, state what remains unknown and identify the evidence that could change the decision.

At governance points, record in the decision log what is known, assumed and uncertain, the agreed risk tolerance and when the decision will be reviewed. This maintains momentum without pretending every fact is settled.

2. Separate evidence from assumption

Critical thinking becomes practical when teams can see how a conclusion was reached. Before approving a recommendation, distinguish verified evidence from interpretation, prediction and assumption.

In business cases, options appraisals and status reports, test the source, supporting evidence, missing perspectives and conditions that would make the conclusion wrong. Ask team members to explain their reasoning, not only present the expected answer.

3. Challenge plans before reality does

Pre-mortems, red-team reviews and scenario exercises expose weaknesses while there is still time to act. Ask a group to imagine that the project has failed and identify the most plausible causes. Give another person or team permission to challenge the preferred option. During simulations, change an important piece of information halfway through so people practice adapting rather than following a fixed script.

Challenge should be directed at the proposal, not the person. Psychological safety allows people to raise inconvenient evidence early, when it is most valuable.

4. Make learning part of delivery

Projects develop resilience through ambiguity, negotiation, setbacks and change. Leaders can use work packages, stretch assignments, mentoring and increasing responsibility to give emerging professionals manageable challenges with appropriate support.

When something goes wrong, examine what the team believed, why it believed it, which signals were overlooked and what should change. Feed the learning into controls, plans and future gate reviews, not only a lessons-learned document.

5. Build resilient systems as well as resilient people

Resilience must not become shorthand for tolerating unreasonable workloads or repeatedly compensating for weak systems. Individual persistence cannot replace realistic plans, clear escalation routes, sufficient capacity and supportive leadership.

Project leaders should identify single points of dependency, plan cover for critical roles, protect recovery time after intense periods and make it safe to report overload. A resilient system enables people to recover and adapt; it does not depend on them absorbing unlimited pressure.

6. Strengthen cognitive resilience around AI

This practical focus builds on my recent APM series on AI and cognitive security, which explored how we protect human judgement and decision-making.

AI can produce polished reports, summaries and recommendations in seconds, but authority of tone is not proof of accuracy. Project teams need verification habits: check important claims against reliable sources, test outputs for omissions and bias, retain human accountability and never allow convenience to replace judgement.

This is part of cognitive security: protecting human judgement in an information environment shaped by misinformation, deepfakes, algorithmic influence and persuasive technology. People who can tolerate uncertainty and being wrong are less likely to accept a simple but unreliable answer merely because it feels reassuring.

7. Practice the response cycle

COVID-19 turned those inherited lessons into a leadership test. In April 2020, while continuing my professional responsibilities, I established Serving Our Superheroes in response to urgent community need. Nobody knew how long the pandemic would last. Guidance changed, supplies were scarce and needs developed faster than a fixed plan could accommodate. The emergency response became a registered charity supporting people in need.

At times the mission could have seemed impossible. We prioritised, established what we knew, acted, listened, monitored results and adapted. We managed changing stakeholders and scarce resources, built delivery relationships and changed direction when the evidence or need changed.

Teams can practise the same cycle through crisis simulations and live project reviews. The aim is not to predict every problem. It is to develop people who can remain effective when reality does not follow the plan.

Make these skills routine

Resilience and critical thinking develop through experience, responsibility and reflection. Organisations should embed them in project induction, risk management, governance, assurance, mentoring and leadership development.

The tools will change and new risks will emerge, but uncertainty will remain. Project leaders who can withstand setbacks, question persuasive information and adapt when the evidence changes will be better equipped to make difficult missions possible.
