An advisory engagement needs a decision to support. Agreeing the question and the limits protects the board from conclusions the work cannot justify.
A board can commission a governance review without agreeing whether it expects a legal compliance opinion, a reading of how decisions work or a proposal for changing authority. The same report may then be treated as all of them. The problem starts before the adviser collects evidence.
A governance advisory brief should prevent that ambiguity. For an investor seeking corporate governance advisory in Mexico, the first task is to name the decision the engagement must support. That decision determines which evidence matters, who must participate and what the adviser can responsibly conclude.
The reference framework also needs a date. The OECD’s Mexico country note, published October 6, 2025, reports that the CCE issued the fourth edition of its corporate governance code in February 2025, adding principles concerning ESG, human rights and diversity. The note identifies recent developments as of June 2025 and otherwise uses information as of December 31, 2024; it should not be read as a legal update through today (OECD Mexico country note).
A commissioning document should therefore identify both the reference being used and the work required to establish its relevance to the company. Naming a code does not define the engagement.
What decision should a governance advisory brief name?
Begin with the decision the sponsor cannot yet make confidently. A board may need to determine whether a committee’s remit should change. An incoming investor may need to understand how reserved matters are handled before agreeing an operating arrangement. These are different questions, even if both require reviewing the same corporate documents.
“Improve governance” gives the adviser no clear boundary. A more useful statement identifies the disputed or uncertain arrangement and the consequence of leaving it unresolved. For example, the board may need to decide whether investment proposals reach it with sufficient analysis before commitments are made elsewhere.
The board and governance diagnostics practice examines how governance works in practice. When that is the assignment, the brief should name the relevant decisions and forums. It should not quietly become an appraisal of every director or a redesign of the entire company.
The sponsor should also state what will not be decided through the engagement. A review of information flows may identify a question about committee composition without providing enough evidence to recommend individual appointments. Recording that boundary protects people from conclusions the work was not designed to support.
Which framework applies to the company being reviewed?
Company form, listing status and ownership arrangements belong in the starting brief. The adviser needs to know which entity is being examined, rather than assume that a group-level policy describes the authority of every subsidiary. The relevant documents should be identified with their effective dates and owners.
The OECD’s 2025 Corporate Governance Factbook distinguishes company law, securities law, additional regulation and listing rules from governance codes. It describes codes as complementary to the legal framework and notes that the balance between formal regulation and a comply-or-explain approach varies across jurisdictions (OECD framework comparison).
For the engagement, the practical implication is to separate a proposed practice from a legal requirement. A recommendation can be useful without being mandatory. Conversely, an arrangement cannot be treated as optional merely because a workshop preferred another design. Qualified counsel should confirm applicability and legal interpretation where those questions arise.
The governance advisory brief should specify the interface with counsel. It can identify who will resolve legal questions and how those answers enter the analysis. It should not imply that an organizational advisory report replaces legal advice, financial audit or transaction due diligence unless a separately qualified and expressly agreed engagement provides that work.
What evidence will distinguish written rules from actual practice?
An approved delegation document describes an intended arrangement. It does not establish how a contested decision travels through the company. The engagement should define which decisions will be traced, which records can be examined and how interview accounts will be compared with documentary evidence.
Consider a hypothetical Mexican subsidiary where investment proposals formally require a local board decision. Interviews suggest that the commercial terms are settled with headquarters before the board receives the paper. The useful question is not simply whether a board meeting occurred. It is what remained open for the board to consider and when its members received the relevant information.
The brief should provide access to evidence that can answer that question. Meeting materials and the sequence of approvals may be more informative than another general questionnaire. The adviser should also seek accounts that could contradict the initial interpretation, rather than collect only confirmation of the sponsor’s concern.
Access limits need to be visible before they become limitations in the final report. If some records or participants will be unavailable, the sponsor and adviser should agree what conclusions remain possible. The absence of evidence is not permission to infer that a practice is either working well or failing.
Who owns the engagement when shareholders disagree?
The person paying for the work may not be the only person affected by its findings. At the outset, distinguish the commissioning sponsor from the body that will receive and act on the report. The arrangement should also specify who can change the question after evidence collection begins.
In an engagement involving a controlling shareholder and an incoming investor, both may want clarity while expecting different conclusions. The adviser needs an explicit mandate, not an instruction to produce a consensus that does not yet exist. Disagreement can be reported and examined without being disguised as a settled position.
The governance advisory brief should define how factual corrections are handled. Participants can be given an appropriate opportunity to correct factual errors without acquiring a veto over unwelcome analysis. The process should distinguish correcting an inaccurate record from negotiating away a supported finding.
Confidentiality requires equally clear arrangements. Establish who may receive which outputs, how sensitive personal information will be treated and what can be shared beyond the commissioning group. A general promise of discretion is not a substitute for knowing who will see an individual comment or how it will be attributed.
What should count as an acceptable final output?
Acceptance should be tied to the agreed question and evidence, not to whether the recommendation pleases every participant. A report should allow the receiving body to see how observations support the conclusions, which interpretations remain uncertain and which matters were not examined.
The brief can require recommendations to identify the decision owner and the condition each proposed change is intended to address. “Clarify roles” leaves too much work hidden. A recommendation to resolve who may return an incomplete investment proposal before it reaches the board gives the sponsor something concrete to consider.
Distinguish receipt of the report from authorization to implement its recommendations. A proposal may require legal review, a corporate resolution or further work before it can be adopted. Those next steps should be visible, along with the person responsible for arranging them. The adviser should not imply that delivery itself changes authority.
Our article on what a board effectiveness assessment measures addresses the substance of that particular inquiry. This commissioning discipline comes earlier: it ensures that the evidence gathered will answer the question the board actually needs to resolve, rather than a broader question no one agreed to commission.
Frequently asked questions
What should a governance advisory brief contain?
A governance advisory brief should identify the decision to be supported, the entity and forums in scope, the evidence required and the limits of the assignment. It should also name who receives the findings and what constitutes acceptable delivery, without promising agreement among participants or a predetermined recommendation.
Does a governance adviser replace the company’s legal counsel?
No. Organizational advice and legal interpretation have different responsibilities. The engagement should establish when counsel is needed to confirm applicable requirements or corporate powers. A practice recommendation should not be presented as a legal opinion, and a legal compliance conclusion should not be assumed from a governance workshop.
Can the scope change after interviews begin?
Yes, but the change should be explicit. The sponsor and adviser should record the new question, the additional evidence needed and the consequences for timing and access. An emerging concern does not justify extending conclusions to people or decisions that the original work was never designed to examine.
Before approving the next proposal, ask the receiving board to finish this sentence: “This work will give us the evidence to decide whether…” Bring that commissioning question to Anker Bioss if the answer still describes a collection of activities rather than a decision the company needs to make.
