Overview
In This Issue
Between 2005 and 2025, France accumulated a series of resounding failures in major public digital projects. From the Louvois project (€600M) to the national payroll office (€346M), including attempts at sovereign search engines, this newsletter provides an uncompromising assessment of 20 years of unfulfilled promises.
The analysis reveals emblematic failures from 2000-2010, the "small" giants that followed (2010-2020), and failed attempts at sovereign AI and search engines. These projects, funded by tax credits, Bpifrance, and research tax credits, reveal recurring structural dysfunctions.
The cross-cutting lessons show that 100% of analyzed projects exceeded their initial deadline by a factor of 2, while 89% had no preliminary business impact study. These repeated failures question the methods of piloting and governing French public digital projects.
The Emblematic Triptych (2000-2010)
Louvois Project: €600M Wasted
2001-2013: 12 Years of Failure
Intended to unify military pay for 600,000 service members, the Louvois project ended in total abandonment in 2013 after consuming nearly 600 million euros.
Dramatic Consequences
€465M in calculation errors in 2012 alone, according to the 2020 Court of Auditors report
Main Failure Causes
- Fragmented governance among multiple actors
- Massive underestimation of business complexity
- Absence of unified and accountable management
- Constant turnover of management teams
National Payroll Office (ONP): The Impossible Ambition
€346M → Total Halt End of 2011
The ambition: create a single payroll system for 2.7 million civil servants. The reality: a project stopped after 4 years and 346 million euros spent, according to the Court of Auditors.
Chaotic Governance
- Project ownership fragmented among 5 ministries
- 3 directors general in 4 years
- 5 successive project directors
Design Flaws
- Excessive ambition, poorly defined scope
- Underestimated business complexity
- Absence of preliminary impact analysis
Cassiopée: 13 Years for a Half-Success
| Period | Objective | Budget Committed | Result | Identified Problems |
|---|---|---|---|---|
| 2001-2014 | Unified criminal information system (Justice) | ~ €300M | Scope drastically reduced | 7 project directors in 13 years |
Disconnect from the Field
The Cassiopée project perfectly illustrates the disconnect between technical ambitions and magistrates' and clerks' real needs. The specifications, too ambitious and constantly modified, led to permanent project instability.
Assessment and Perspectives
20 Years of Systemic Failures
Between 2005 and 2025, over 1.2 billion euros were wasted on aborted or largely failed French public digital projects. From the Louvois-ONP-Cassiopée triptych to digital sovereignty attempts with Quaero and Qwant, the same mistakes repeat endlessly.
Toward a Systemic Approach
These repeated failures are not inevitable but stem from structural methodological flaws. Analysis reveals recurring patterns that could be avoided through a more rigorous approach and strengthened controls.
Priority Recommendations
- Unified governance with clear accountability
- Systematic incremental approach
- Mandatory minimum internal expertise
- Independent audits at fixed intervals
- Quantified success metrics from the start
