Activating Collective Capability at the Board Table
A board’s effectiveness is shaped by its dynamics - the shared behavioural norms that determine whether directors’ capabilities are activated, amplified, or suppressed.
While board performance relies on three drivers - directors, systems, and dynamics - Archetype focuses on the third. We partner with boards and chairs to transform how they work together.
The regulatory context
New Zealand boards operate under the Companies Act 1993. The Reserve Bank and Financial Markets Authority's 2023 joint Governance Thematic Review named board behaviours and capabilities as integral to effective governance.
The report calls on boards to ensure they have "appropriate processes, practices and capabilities" to provide "direction, challenge and oversight," and notes that "the tone set by the board and reinforced through its behaviours is an integral part of effective governance."
Our practice develops the capability and behaviours the review names.
“Behavioural norms have the most direct link to company-level outcomes (such as risk management).”
A Harvard Business School study of hundreds of boards found that how well the board functioned as a team was strongly associated with its overall effectiveness – alongside structure, process, and composition. Research tracking individual directors across multiple companies found that a director's transferable contribution accounts for roughly a tenth of the variation in firm performance. – The board context they sit within - the board’s dynamics - has a greater influence.
A 2026 director survey published on the Harvard Law School Forum on Corporate Governance identified "board culture and dynamics" as the second-ranked driver of board effectiveness.
EY's Board Matters research identifies culture as one of three core drivers of board performance, alongside information flow and composition.
These findings point to three drivers of board performance that operate at different layers.
“High-functioning boards today need highly developed cultures, with firmly established behavioural norms and values that promote trust, candor, courage, inclusion, confidentiality, continuous learning, and accountability, and that support better decision-making.”
What the research shows
Three drivers of board performance
Board performance is driven by three inputs – the directors, the board's systems, and the board's dynamics. If all three are strong teh board is likely to be consistently effective.
The director – individual capability: the skills, experience, and judgement a director brings to the table. Director recruitment, onboarding, and continuing education develop this layer.
The board's systems – governance infrastructure: agendas, board packs, evaluations, charters, registers. Administration and evaluation tools (BoardPro, Diligent, Board Benchmarking, the Institute of Directors) serve this layer.
The board's dynamics – the shared behavioural norms and interaction patterns that determine whether a director's input is activated, amplified, or suppressed.
In New Zealand, the first two inputs - directors and systems - have an established ecosystem of providers, tools, assessment and development.
Board dynamics not as well served with fewer rescues and less investment in their development. Nearly all New Zealand boards would benefit from investing more in honing their dynamics.
“Boards that function effectively as a team have up to 8x the impact on firm profitability than any one well-qualified board director.”
What is board effectiveness?
Board effectiveness is how well a board fulfils its governance responsibilities and contributes to organisational performance. It encompasses the board's strategic direction, risk oversight, and the quality of its decisions.
Underpinning all three is the behavioural layer - how directors work together. This is the space we work in with boards.
The four dynamics critical to board effectiveness
We work with the four behavioural dynamics must be high-functioning for a board's members to be collectively effective.
Psychological safety and speaking up – whether every director can voice a doubt, ask a question, or offer a contrary view without psychological risk.
Genuine challenge – whether directors constructively examine what management presents, topics brought to the table, and each other’s contributions.
Quality of debate – whether the board works through positions with inquiry as well as advocacy, drawing on the full range of expertise in the room. A board that gravitates to agreement before issues are examined and resolved risks incomplete thinking and inadequately informed decisions.
Decision quality – whether decisions are made well: the right people consulted, the right questions asked, a willingness to disagree and then commit. Complete clarity. A board can have safety, challenge, and robust debate, and still produce poor decisions if the decision process is rushed or unclear.
When all four are strong, the board operates at its collective capability. When any is weak a board operates below its capability.
How we work with a board
Our board development is structured and practical – we work on how a board behaves in the room, not pushing generic governance training. We work with the people in the room and their collective ways of working to help them build a more effective way of working together.
Discovery. Assessment of how the board operates, focusing on the four dynamics – where the room is strong, and where director capability is being reduced by board dynamics.
Design. Identifying and tailoring the content and structure of the workshop or programme. Tailored to the board’s needs. Agreed with the board prior to delivery..
Delivery. One or more workshops, often individual director conversations, and possibly in-meeting observation.
Work targets the dynamics of the board that need development – building the psychological safety, the conditions for genuine challenge, improving the quality of debate, or sharpening decision processes.
The work uses the board's real issues to progress both their ways of working and the work.
Given boards are time poor and only assemble for planned meetings our workshops typically integrate with board meetings, often in 90-minute windows. If complementary one-to-one sessions are being used, they are scheduled to suit each member.
When boards engage us
Typically, three situations bring boards to this work:
A chair, director or the board as a whole recognises the board could function better. Some directors simply know the board could work better than it does and want to proactively address that..
A board assessment or review identifies the ‘board dynamic’ should be better. The review identifies a gap. We won with the board to close it – the development work assessments ands reviews identify but do not address.
Responding to the RBNZ and FMA governance review. The review’s focus on board dynamics compels the board to address this driver of its performance.
Frequently Asked Questions
What is board effectiveness?
Board effectiveness is the degree to which a board fulfils its governance responsibilities and contributes to organisational performance. Research finds that how a board works together – its dynamics – is central to effectiveness. Board dynamics include whether directors feel safe to speak up, whether challenge is genuine, whether debate is real, and whether decisions are made well.
What are board dynamics?
Board dynamics are the shared behavioural norms and interaction patterns that determine how a board works together. They sit between the individual director and the board's formal systems – the layer that determines whether a director's capability is activated, amplified, or suppressed.
How do board dynamics affect director performance?
Research tracking the same directors across multiple companies finds that individual directors account for roughly a tenth of the variation in firm performance (ECGI). The larger share is shaped by the board context the director sits within. A director's contribution is not fixed – it is activated, amplified, or suppressed by the board's dynamics.
What is the strongest predictor of board effectiveness?
How well a board works together is the strongest predictor of board effectiveness – ahead of structure, process, and composition. A Harvard Business School study of hundreds of boards found that how well the board worked as a team was strongly associated with its overall effectiveness (Harvard Business School). Separate research found that how the board works together predicted board effectiveness three to five times more strongly than who was on it (Journal of Organizational Behavior).
What is the difference between board composition and board dynamics?
Board composition is who is on the board – the mix of skills, experience, independence, and diversity. Board dynamics is how the board works together – the behavioural norms and interaction patterns that determine whether that capability is used. Composition is about selection; dynamics is about activation.
How can boards improve their dynamics?
Boards improve their dynamics through structured diagnosis and targeted development. The first step is an assessment of how the board performs across the four key dynamics: psychological safety and speaking up, genuine challenge, quality of debate, and decision quality. Development work then focuses on the specific dynamics where the board is weakest, grounded in behavioural science and tailored to the particular board.
How does psychological safety affect board performance?
Psychological safety is the condition that allows every director to speak up – to voice a doubt, ask a question, or offer a view that runs against the room. Without it, boards lose access to the full capability in the room: directors self-censor, concerns go unexpressed, and the board operates below its collective intelligence. It is the foundation on which challenge, debate, and decision quality depend.
What is the three-driver model of board performance?
Board performance operates across three drivers: the director (individual capability), the board's systems (administration, evaluation, and governance infrastructure), and the board's dynamics (the shared behavioural norms that determine whether director input is activated, amplified, or suppressed). Most governance investment goes to the first two drivers. The evidence suggests the third driver has the greatest leverage and receives the least dedicated attention.
