They measure their maturity with Datamensio
An example
This could be your situation.
Take one company as an example: three sites, three spreadsheets, no shared answer.
Nobody can consolidate.
Nordhavn Industries, 2,400 people in Hamburg, Lyon and Porto. A client asks where the group stands. Each site answers in its own spreadsheet, with its own scales.
Three weeks, a single base.
One COBAC instructions on prudential reporting (CERBER and periodic returns) assessment launched across all three sites at once, from the managers’ interview notes. The framework was already written, its 10 themes and levels L1 to L5 too.
Two costs avoided before being committed.
A score of 53 out of 100, with the gap concentrated on three themes. The AI companion spotted that two actions duplicated those of another audit. The committee report took one sentence to request.
What it saved them
- 3sites measured on the same base, instead of three questionnaires to reconcile
- 2duplicate actions caught before the spend
- 1committee report, with no manual rework
These figures are an example. They could be yours.
The standard imposes processes. Datamensio says where you stand.
01
The framework is already written
Themes, questions and levels L1 to L5, all written. You do not start from an empty spreadsheet.
02
The score lands the same day
Online, by self-assessment link or in interview. Theme by theme, comparable over time.
03
The gap becomes a costed plan
Every step up carries its action. The AI prioritises on expected effect, not on the order of the standard.
04
Progress can be demonstrated
Campaign after campaign, against your target and against your own past. That is what your board asks for.
The maturity scale
One level, the next, and the action that links the two.
It is this mechanism (one level, the level above, and the action linking the two) that turns a finding into a trajectory.
Are consistency checks run on prudential returns before they are transmitted to COBAC?
- N1
No formal check before submission. Anomalies are identified when the supervisor flags them.
- N2
Checks are carried out by the preparer, based on experience, with no checklist and no record kept.
- N3
A consistency checklist is defined and applied before each submission. Results are retained.
- N4
Checks are tool-supported, blocking in case of a deviation beyond a threshold, and reviewed by someone other than the preparer.
- N5
The checklist is updated with every change to the instructions and after every anomaly found, with documented tracking of revisions and correction deadlines.
Action to move from L2 to L3
Formalise the list of cross-return consistency checks, attach it to the submission procedure, and have the preparer sign the control sheet at each monthly close before transmission.
« With Datamensio, we meet our objectives far more efficiently. The ERDF inspection services and our supervising ministry particularly appreciated an approach that gives them reliable data. »

What this framework covers
The instructions of the Central African Banking Commission organise the periodic submission of prudential and accounting returns by regulated institutions, through the CERBER declarative system. They specify the nomenclature of returns, the rules for feeding them from the credit institutions’ chart of accounts, monthly, quarterly, half-yearly and annual frequencies, transmission deadlines and correction procedures. On top of these returns come declarations relating to prudential ratios, risk concentration, liquidity and foreign exchange position. Formal compliance with these obligations is verifiable, and it is verified.
In practice, the difficulty lies not in knowing the texts but in the chain that produces the data. Are the returns fed automatically from the banking information system, or reconstructed every month in spreadsheets that only one person knows how to handle? Are consistency checks between returns run before transmission, or discovered when reading the supervisor’s observations? Who formally signs off a submission, and on what basis? When a manual adjustment is made, does a usable trace of it remain six months later?
Two confusions come up repeatedly. The first is treating prudential reporting as an extension of accounting production: prudential bases, weightings and capital deductions follow their own rules, and an accurate accounting close does not guarantee an accurate prudential return. The second is treating submission as an end in itself. The progressive convergence of the CEMAC framework towards Basel standards has tightened the requirements for quality, traceability and justification of the data submitted.
A compliance check ends with a binary finding: the return was submitted on time, or it was not. The maturity assessment asks a different question: what level of control does the production chain sit at, and what specific action moves it up a level. A one-off submission achieved through exceptional effort does not carry the same value as a submission produced by a documented, controlled and repeatable process. The gap between the score obtained and the target generates the action plan, which the AI groups into a prioritised roadmap.
The framework is ready to use in Datamensio. You can adapt it to your organisation: the AI adjusts the themes, questions and levels according to the CMMI method, or builds a variant from your internal procedures and existing returns. A group present in several countries in the region can apply the framework by subsidiary and compare results.

A short version of the framework is available for the online self-assessment.
Frequently asked questions
Does this assessment amount to a certificate of compliance with COBAC?
No. Datamensio measures the maturity of your declarative arrangements and prepares exchanges with the supervisor. It issues no certificate and does not replace the on-site or off-site inspections carried out by the Banking Commission.
What is the difference between this assessment and a standard compliance check?
A compliance check verifies that a return was submitted, complete and on time, and ends with a gap finding. The maturity assessment places the production chain on a progressive scale and indicates the action that moves it up a level. The two complement each other: the assessment explains why a gap keeps recurring.
How long does the assessment take?
The short version is completed in a single working session with the reporting manager. The full version, run collaboratively with accounting, risk and permanent control, takes one to two weeks, most of the time spent gathering evidence from each contributor.
Can the framework be adapted to our institution?
Yes. Themes, questions and levels can all be changed. The AI can build a variant from your internal procedures, your return nomenclature and your organisation. Ownership of the framework stays with you.
Can several subsidiaries in the CEMAC region be compared?
Yes. The same framework can be rolled out across several business units, with a score per entity and a benchmark between them or against previous cycles. A cross-entity roadmap consolidates the action plans of the different subsidiaries.
Do respondents need technical expertise in the information system?
The questions cover organisation, controls and traceability, not application configuration. Some questions relating to how returns are fed do call for input from an IT contact: the collaborative mode allows them to be assigned directly to that person.
How does this assessment fit with internal control and ICAAP?
The quality of the data submitted underpins the credibility of ratios and internal capital analyses. A solid reporting assessment provides a reusable base for the internal control and ICAAP frameworks, without duplicating actions.
Where is the data hosted?
In France, with OVH, with backup at Scaleway. No transfer outside the European Union. The AI models used can be selected, including from European solutions.
