A clear picture.
Decisions that help.
We analyse your application, your architecture and your practices to build a prioritised action plan that fits the constraints of your business.
PrioritiseRisks, debt & value
TransformTrajectory & steps
Understand the old system to choose the transformation that helps.
The audit separates facts, risks and options before committing to a modernisation.
A reading of the existing system that lets you decide.
An audit must lead to usable decisions: which risks to handle, which points to explore and which work to prioritise. We separate the findings, their consequences and the recommendations.
Before taking over a piece of software.
Assess the available sources, the dependencies, the deployment and the knowledge still reachable.
When the symptoms pile up.
Look for the areas that deserve investigation, document the observations and avoid conclusions without measurement.
Before deciding to rebuild everything.
Compare progressive evolution, partial replacement and full rebuild against the cost of change and the continuity constraints.
SCOPE OF WORKWhat we do,
What we do,
in practice.
01
Define the question the audit answers
State the decisions expected, the parts of the system involved and the sources available. An audit has a different scope when it prepares a takeover, a migration or a performance analysis.
02
Examine and document
Study architecture, dependencies, code, data, operations and practices within the scope. Separate what is observed from what requires further measurement or access.
03
Prioritise the recommendations
Tie every action to a risk or an objective. Describe the effort to investigate, the dependencies and the expected result, so the plan can be discussed with decision-makers.
04
Build a trajectory
Present transformation scenarios and their trade-offs. Plan progressive validation and a handover of the findings to the team that will do the work.
THE DELIVERABLESEnough to decide,
Enough to decide,
validate and take over.
The documents and the work serve your team. Their level of detail is defined by the scope and the criticality of the project.
GOOD TO KNOW
The initial diagnosis serves to define the scope. An in-depth audit is a assignment of its own, with identified deliverables.

PREPARING OUR CONVERSATIONWhat helps us
What helps us
frame the work.
- Your business objective and the users involved.
- The existing systems, the dependencies and who is available.
- The constraints on schedule, budget and operations.
- The criteria that will let us validate the result.
THE USEFUL QUESTIONS
Clarify before committing.
Does the audit include the fixes?
Diagnosis and fixes are kept separate. Immediate actions can be included in the assignment, but their scope and validation must be explicit.
Is this a certifying security audit?
What is described here is a technical audit. A specialised security assignment or a certification requires a distinct framework and distinct skills.
CONCRETE EXAMPLE / SCENARIO
Decide how to take over an ageing application.
IT department / application estate
Illustrative scenario, not attributed to a real client.
01 / The starting situation
A critical tool still works but releases are difficult and the knowledge is concentrated at one supplier. A full rebuild is being considered without a complete picture.
02 / Our intervention
Examine the accessible scope, document the dependencies and risks, then compare a progressive takeover, a module-by-module replacement and a full rebuild.
03 / What would be delivered
A documented diagnosis and reasoned scenarios that allow the trajectory to be chosen before committing to the build.
A clear scope.
