A guide to constructive challenge

Daniel Taylor looks at the art and science of effective constructive challenge—a good governance game changer

Constructive challenge is a hallmark of mature, effective boards. It enables robust scrutiny, safeguards strategic decisions, fosters accountability, and strengthens group dynamics. Successfully embedded, it transforms culture from passive acceptance into a dynamic environment where insight, trust, and shared ownership flourish.

What is constructive challenge?

Constructive challenge is the practice of questioning, probing, and testing ideas, decisions, and assumptions in a way that is purposeful, evidence-informed, and respectful. Its aim is to strengthen decision-making, ensure accountability, and surface better options—without undermining trust or damaging relationships.

It involves:

• intent – to clarify, improve, or assure, not to score points
• approach – using open, relevant, and well-prepared questions that are proportionate to the stakes
• tone – balancing rigour with respect, ensuring the recipient feels engaged, not attacked
• outcome focus – moving discussion towards insight, consensus, and sound decisions rather than stalemate.

In the context of governance, constructive challenge sits at the intersection of scrutiny (ensuring decisions are robust), support (helping the executive succeed), and stewardship (protecting organisational purpose and values). It is a core skill of non-executives, but it also applies to executives when they challenge peers or themselves.

Why constructive challenge matters

Constructive challenge isn’t just a nicety; it’s the backbone of effective governance in public-purpose organisations. The post-2008 banking review led by Sir David Walker and Sir Robert Francis’s NHS Inquiry found that a key root cause of the failures was a pervasive absence of constructive challenge.

In boards that champion questioning, there is less mistrust and more co-creating consensus and accountability. When boards and governing bodies fail to question assumptions or surface uncomfortable truths, strategic missteps go unchecked, and the consequences are often systemic and public-facing. In public service landscapes, where trust, accountability, and impact matter most, the cost of complacency can be profound.

Recent scrutiny into the University of Dundee’s financial collapse by Professor Gillies starkly highlights this reality. The investigation revealed that a culture of dismissing dissent, discouraging scrutiny, and promoting a ‘positive narrative’ masked severe mismanagement and misreporting. Time and again across the higher education sector, leaders have underscored that independent, empowered governors and leaders willing to be challenged are essential to preventing governance breakdown.

Public-purpose organisations – be they councils, universities, NHS trusts or regulators – demand governance cultures in which robust scrutiny is welcomed, not viewed as a threat. The Nolan Principles, enshrining values such as integrity, accountability, and objectivity, explicitly call on public officeholders to ‘challenge poor behaviour wherever it occurs’. Similarly, GGi emphasises that challenge is a strategic tool, not a sign of mistrust—and that questioning sharpens, rather than derails, collective decision-making. The Grant Thornton report into local government failure echoes this: once relationships break down and challenging voices go silent, governance collapses and failure follow.

Many UK corporate governance codes explicitly mandate that non-executive directors should constructively challenge and help develop strategy.

Who does what?

Board vs committees

Committees (audit, remuneration, risk, etc.) serve as deep-dive arenas for focused scrutiny, while the full board ensures strategic coherence. Each level must foster challenge: committees interrogate detail, the board integrates and balances these findings across the organisation.

Executive vs non-executive dynamics

Executive directors face inherent conflicts between involvement and scrutiny. Non-executives (NEDs) provide independent oversight and bring detached objectivity, yet must also contribute constructively, not just critique. NEDs’ ability to challenge effectively is moderated by their motivations: those driven by shared organisational purpose – not self-interest – are most effective.

Chair’s role

On any board the chair plays a pivotal role: cultivating the culture, ensuring inclusion, addressing power imbalances, and setting expectations that challenge is positive and expected. They must create psychological safety and normalise questioning. That includes providing non-executives with insight and tools (such as GGi’s board assurance prompts) to feel confident in challenging even highly technical subjects.

Spectrum of constructive challenge: high value

Constructive challenge is a spectrum, like anything. There are high-impact, high-value forms of questioning and there are lower value forms, and everything in between:

• High-value forms of challenge often feel more uncomfortable because they question fundamentals—but they are also the most transformative.
• Mid-value challenges improve execution, resilience, and delivery but may not shift the organisation’s trajectory.
• Low-value challenges still have a place—they protect the integrity of information—but should not dominate scarce board time.

Part of the art is knowing when and how to utilise each and trying to cultivate a discursive environment at board, especially of maximally high value challenge.

The continuum of constructive challenge: the art of asking questions

So, what are the key types of challenge questions and which ones deliver the greatest value in board and committee discussions?

1. Clarifying – Ensure understanding and precision
   Purpose: To avoid misinterpretation.
   Example: “What exactly did we mean by the term ‘adjusted EBITA’ in this context?”
2. Reframing / Reflective – Align with strategic context
   Purpose: To ground proposals in higher-level goals.
   Example: “How does this proposed change reinforce our transformation goals?”
3. Assurance-testing / Evidence-based – Test underlying assumptions
   Purpose: To assess rigour in reasoning.
   Example: “What evidence supports this assumption in our model?”
4. Insight / Hypothetical – Explore alternative futures
   Purpose: To surface vulnerabilities or opportunities.
   Example: “If a competitor enters the market, how would this scenario evolve?”
5. Strategic / Accountability – Drive action and ownership
   Purpose: To create commitment and clarity on next steps.
   Example: “What is our timeline for implementation, and when will we review progress?”

Questions in practice:

• Clarifying: “Can you explain how you derived revenue assumptions?” – ensures factual grounding.
• Framing: “Where does this fit with our digital transformation ambitions?” – aligns context.
• Assurance-testing: “What risks could undermine the projected margin?” – tests resilience.
• Insight-oriented: “If regulation shifts, how might customer demand evolve?” – scenario thinking.
• Strategic: “When will management report back on implementation progress?” – creates accountability.
• Clarifying: “Could you walk us through the calculation logic on slide 7?” – prevents assumptions and ensures alignment.
• Reflective: “How does this fit with our long-term sustainability narrative?” – grounds decisions in vision.
• Assurance-testing: “What sensitivity analyses have we run in case input variables shift?” – tests resilience.
• Insight: “What if regulatory changes accelerate sooner than anticipated?” – probes adaptability.
• Strategic: “Who is accountable for rolling this out, and what are their performance targets?” – drives action.

Asking the right questions at the right time to receive the right answers is the essence of governance quality.

Cultural environment required for effective constructive challenge

We often say culture doesn’t just eat strategy for breakfast; it eats governance too. Like so many areas of governance, effective and impactful constructure challenge is only possible in the right cultural conditions and done in the right way, with the right approach tone and behaviours. The environment for effective constructive challenge doesn’t just exist, it must be developed. Some of the cultural hallmarks are:

• Psychological safety: board members must feel comfortable dissenting or raising concerns without fear, enabling organisational dissent to act as a constructive signal.
• Trust and candour: trust leads to respectful challenge. GGI highlights facilitated board development as a way to nurture this.
• Leadership modelling: chairs set tone, handling conflict swiftly, preventing breakdowns in respect.
• Avoiding blame culture: blame inhibits problem-solving. Boards must create environments that promote learning, not finger-pointing.
• Diversity and engagement: diverse perspectives and engagement at all levels help prevent groupthink and enrich decision quality.
• Structured self-assessment: GGi’s QA maturity matrix encourages boards to self-assess challenge culture and identify aspirational improvements.
• Avoiding bias traps: groupthink, status quo bias must be countered via diversity of thought and structured dissent.

At GGi we are big fans of the Sonnenfeld trust, candour respect model:

Jeffrey Sonnenfeld’s concept offers a valuable cultural lens for understanding how constructive challenge flourishes in high-performing boards and leadership teams. His circle model shows how these three elements feed one another in a reinforcing cycle: mutual respect builds trust; trust encourages the open sharing of even difficult or uncomfortable information; having the same information enables members to challenge one another on equal footing; and through such open, coherent challenge, mutual respect deepens further.

In the context of constructive challenge, this means that challenge is not perceived as hostility or personal criticism, but as a shared responsibility for reaching the best possible decision. When board members trust one another’s intentions, are candid in both giving and receiving feedback, and maintain a foundation of respect regardless of disagreement, they create a safe environment for robust debate.

In public-purpose organisations, where transparency, accountability, and collective stewardship are central, embedding Sonnenfeld’s principles transforms challenge from a potential source of friction into a disciplined, respectful practice that strengthens both decisions and relationships.

Preparation guide for NEDs: from papers to live discussion

At GGI we have developed this systematic guide to help NEDs confidently translate analysis into effective, constructive challenge during board meetings.

This structure helps NEDs translate reading into impactful, live questioning.

Cultivating constructive challenge: interactions

It’s a three-way ballet dance, with the chair, executives and non-executives each playing a key role:

• Chair: sets norms, clarifies expectations, models openness, swiftly addresses deviations.
• Executives: pre-engage with NEDs to build mutual understanding and reduce defensiveness-making challenge collaborative, not adversarial.
• NEDs: prepare deliberately, diversify question types, embrace being the “dissenting voice” in service of governance.

In a bit more detail:

The chair – cultural architect and guardian of process

The chair is the linchpin in embedding constructive challenge as a healthy, valued part of governance. They set the tone by making explicit that challenge is not only acceptable but expected as part of fulfilling fiduciary and stewardship duties. This includes:

• setting clear norms for respectful dialogue and encouraging diversity of perspective
• clarifying expectations around preparation, participation, and the value of evidence-based questioning
• modelling openness by inviting critique of their own decisions and demonstrating curiosity when challenged
• intervening swiftly if debate becomes personal, defensive, or strays into operational detail, keeping discussions at the right strategic level.

The most effective chairs act as facilitators rather than arbiters, balancing contributions, ensuring quieter voices are heard, and guiding the conversation towards consensus without diluting rigour.

Executives – enablers of informed, collaborative scrutiny

Executive leaders hold the detailed knowledge of the organisation’s operations and strategy, but constructive challenge works best when they share that knowledge openly. Executives can enable effective challenge by:

• pre-engaging with non-executives ahead of meetings to build understanding, answer clarifying questions and prevent surprises
• presenting issues transparently, including risks, weaknesses and trade-offs, rather than only highlighting positives
• framing information so that NEDs can see both the strategic context and the operational realities
• responding to challenge with openness, avoiding defensiveness, and recognising that scrutiny is a form of support for achieving organisational goals.

When executives view challenge as a collaborative exercise in problem-solving, not an adversarial test—they help create the conditions for better decisions and stronger board relationships.

Non-executive directors – informed, courageous stewards

NEDs have a unique vantage point: they are independent from daily operations yet responsible for ensuring strategic integrity, risk oversight, and value for stakeholders. To fulfil this role, they should:

• prepare deliberately by thoroughly reviewing papers, identifying key questions, and considering the broader policy and societal context
• diversify questioning styles—moving between clarifying, probing, strategic, and future-oriented questions depending on the need
• embrace the role of constructive dissent, asking the questions others may hesitate to voice, provided it is done with respect and in service of the organisation’s purpose
• draw on their external perspectives and experience to bring fresh thinking and prevent groupthink.

Effective NEDs are not constant contrarians; they calibrate their challenge to be proportionate, timely, and solution oriented.

Summary and conclusion

In essence, constructive challenge is an active culture, not a one-off tactic. It requires:

• a spectrum of question types, from clarifying to strategic
• embedding challenge across board and committees
• clear roles and balanced power
• a culture of candour, trust, and shared purpose
• training and preparation tools to empower all members
• leadership that frames challenge as constructive, not combative.

Constructive challenge is not adversarial, it’s foundational. For organisations serving the public good, it ensures transparency, nurtures resilience, and helps maintain public trust. The Walker, Francis, and Gillies investigations all teach the same lesson: failure to challenge is failure to govern. And in contexts where public value is at stake, that failure isn’t just costly, it’s unacceptable.

Constructive challenge is foundational to effective corporate governance. It encompasses deliberate, respectful scrutiny designed to test assumptions, sharpen strategy, and strengthen accountability. Boards that embed this culture experience greater clarity, resilience, and alignment.

Constructive challenge bridges the gap between trust and oversight, it isn’t adversarial but purpose-driven, catalysing both consensus and shared accountability. Embedding this art requires deliberate cultural architecture, leadership modelling, and the skills to ask and listen effectively. This deep dive provides the strategy, spectrum, culture, and preparation frameworks needed to elevate boardroom challenge.

Effective constructive challenge is something that needs to be worked at. GGi is here to help.
