Failing IT projects: is IT system mapping the missing link?

Cloud migration, application modernization, agile transformation… Despite skilled teams and clear intentions, many IT projects fail or fall critically behind. And the culprit is often invisible: an incomplete or non-existent IT system map.

Hidden dependencies = uncontrolled risks

Failure doesn’t always come from poor planning or wrong technology choices. It often comes from a forgotten element in the system:

• An unidentified technical dependency
• An ignored critical flow
• An undocumented obsolete component

The result: a project that was supposed to take 3 months takes 9. A minor change triggers an outage. An application thought to be isolated turns out to interact with 10 others.

Real-world example: the Gifi ERP migration failure

In 2023, Gifi launched an ERP migration to modernize its IT system. Without a clear view of critical flows and dependencies, the rollout caused:

• Logistical chaos (sales reporting blocked)
• Stock-outs in stores
• Delivery errors
• And ultimately, a massive revenue loss, forcing Gifi to take out a €100 million loan

The lack of a complete technical map turned a strategic project into an operational crisis and put the company at risk of bankruptcy.

The classic reflex: “let’s run an audit”

When visibility is missing, teams often launch a manual audit: interviews, Excel sheets, Visio diagrams…

But that approach is:

• Slow
• Incomplete
• Quickly outdated

The solution: a living map driven by flows

A map should not be a frozen deliverable, but a real-time steering tool.

It should let you:

• Visualize flows between applications, technical components, and networks
• Identify critical dependencies before any change
• Verify compliance with IT system rules

That’s exactly what Uncia provides: a platform that automatically documents your technical architecture, maps flows, and detects gaps or risk areas.

A good project starts with a good map

An IT project is like a renovation site. Without the blueprints, you knock down a wall… and discover a gas pipe you didn’t know about.

Mapping before acting means avoiding nasty surprises. And above all, it secures your projects, your budgets, and your credibility.

Plan your next IT project with confidence. Map it first. Try Uncia.
