How supervisory boards stay informed and involved without taking over management
Dutch governance is built on a clear distinction. The executive board manages the organisation. The supervisory board monitors its policy, advises the executive board and acts as its employer.
That division appears straightforward. In practice, it is one of the most difficult aspects of supervision.
A supervisory board that remains too distant may lack the information needed to understand what is happening. A board that becomes too involved can weaken executive responsibility and eventually find itself assessing decisions it helped to make.
Good supervision therefore requires more than distance. It requires informed involvement, independent judgement and clarity about who is responsible for each decision.
Distance is not the objective
Distance is often treated as a defining characteristic of supervision. It protects independence and prevents supervisory board members from becoming part of daily management.
But distance has no value by itself.
A supervisory board can be formally independent while having an incomplete view of the organization. Reports may show that targets are being met while concerns about culture, execution or leadership remain invisible. Problems often become apparent only after they have already affected performance, continuity or stakeholder confidence.
The relevant question is not how much distance a supervisory board maintains. The question is whether it has sufficient insight to form an independent judgement.
The Dutch Corporate Governance Code 2025 reflects this. It expects executive directors to provide information actively but also places responsibility on supervisory board members to obtain the information they need. Supervision is not a passive process in which the board waits for management reports.
Information is a responsibility of the supervisory board
The executive board remains responsible for establishing reliable information procedures. It must ensure that relevant information reaches the supervisory board in time.
That does not remove the responsibility of the supervisory board to consider the quality and completeness of what it receives.
Financial reports and performance indicators provide only part of the picture. Effective supervision may also require contact with the external accountant, internal audit, the works council, client or employee representatives and members of senior management.
The Governancecode Zorg 2022 makes this responsibility explicit. The supervisory board, and each member individually, has its own responsibility for obtaining information.
Broader access to the organisation must be organised carefully. Individual supervisory board members should not issue instructions to managers or create informal reporting structures alongside the executive board. Agreements about contact, information and confidentiality should therefore be clear to everyone involved.
The purpose is to improve the quality of oversight, not to create a second management structure.
The advisory role can blur responsibilities
A supervisory board does more than monitor. It also advises the executive board and acts as a sounding board on strategy, risk and organisational development.
This advisory role is valuable, particularly when decisions are complex or difficult to reverse. It can also create ambiguity.
When supervisory board members become closely involved in developing a proposal, it may become harder for them to assess that proposal independently later. Advice can gradually become direction. Executive directors may also seek collective ownership of a difficult decision by placing it informally with the supervisory board.
The distinction must remain clear. Management develops proposals, weighs the options and owns the decision. The supervisory board tests the reasoning, challenges assumptions and decides whether approval is required within its formal powers.
Early involvement is not necessarily a problem. The Vereniging van Toezichthouders in Woningcorporaties notes that supervisory boards are increasingly involved in strategic dialogue before a plan is complete. This can improve decision quality, provided that each party remains clear about its role.
A useful boardroom question is: are we helping management to think, or are we deciding on its behalf?
More intensive supervision does not mean management
The required level of involvement can change.
A financial crisis, leadership transition, major acquisition, serious operational failure or threat to continuity may justify more frequent meetings and more detailed reporting. The supervisory board may request scenarios, monitor recovery measures closely and maintain regular contact with the chair of the executive board.
That is intensified supervision. It is not the same as taking control of the organization.
The Corporate Governance Code draws a clear boundary. A delegated supervisory board member may perform a temporary special task involving closer supervision and advice, but the delegation may not include managing the company. If a supervisory board member temporarily assumes an executive role because directors are absent or unable to act, that person must leave the supervisory board for that period.
These boundaries protect accountability. Employees and stakeholders must be able to identify who makes executive decisions and who independently supervises them.
A crisis may change the frequency and depth of supervision. It does not automatically change the allocation of responsibility.
Role clarity requires more than formal documents
Statutes and board regulations define powers, approval rights and formal reporting lines. They are necessary, but they do not resolve every situation encountered in practice.
Role clarity is also created through behaviour.
It is visible in the questions supervisory board members ask, the way the chair communicates with the executive board and how the board responds when performance falls short. It is tested when information is incomplete, trust is under pressure or an urgent decision must be made.
Each supervisory board should therefore discuss several practical questions:
- Which decisions belong exclusively to the executive board?
- Which decisions require formal approval?
- What information does the supervisory board need and from whom?
- Which developments would justify intensified supervision?
- How will the board return to its regular role after an exceptional period?
These questions should be answered before a crisis occurs.
Evaluation should examine actual behaviour
Annual evaluation has become standard practice. The latest Dutch monitoring report on the 2024 financial year found that virtually all participating companies evaluate the functioning of their executive and supervisory boards each year.
The same report shows that formal evaluation does not automatically produce meaningful reflection. Twenty nine percent of respondents did not involve an external expert in the evaluation of the supervisory board. Compliance with the reporting requirements for board evaluations was 59 percent, compared with approximately 80 percent in 2019. The decline was largely related to stronger requirements for reporting the findings and follow up actions.
An effective evaluation should therefore go beyond meeting schedules, attendance and formal procedures.
It should examine situations in which roles became unclear.
Did the supervisory board obtain information early enough?
Was management challenged without being displaced?
Were difficult issues discussed openly?
Did the board intervene when necessary?
Were lessons translated into changes in behavior?
The quality of governance becomes visible in how boards respond to these questions.
Close enough to understand
Effective supervision cannot be reduced to either distance or involvement.
A supervisory board must be close enough to understand the organisation, its people and its risks. It must remain independent enough to challenge management and reach its own conclusions. When circumstances require intervention, it must act without leaving uncertainty about who is responsible for managing the organisation.
The strongest supervisory boards do not avoid the boundary between governance and management. They recognise it, discuss it and know when they are approaching it.
That is what allows them to remain involved without taking over.
