Midsize industrial: HRIS recovery

DRAFT — to be replaced by author content

Context

The terrain: a midsize company in the industrial equipment sector, around three thousand two hundred employees, four production sites and a central headquarters. The company, controlled by a European investment fund since 2021, has known three successive HR directors in five years. The HRIS, deployed in several waves between 2018 and 2022, has never been the subject of complete acceptance and accumulates technical debts on the payroll, time management, talent and training modules.

The arrival of a new HR director in September 2025, hired explicitly to stabilize the function, coincided with two payroll incidents over three consecutive months. The subject, long contained internally, leaked into the regional press in late November. The executive committee inscribed HRIS recovery among the strategic priorities of fiscal year 2026.

Problem

The initial analysis, conducted by the new HR director with an external audit mandated in parallel, brought to light three superimposed problems.

The first problem, the most immediate, concerned the reliability of monthly payroll. The pre-closing controls, theoretically planned, were in reality entrusted to an insufficient number of employees, several of whom had left the company without documented handover. Payroll anomalies reached a level structurally higher than sector standards, without the IT department having a consolidated measurement.

The second problem concerned functional consistency. The time management and payroll modules had been configured by different vendors, at different moments, without common documentation. Management rules diverged subtly between modules, producing gaps that revealed themselves only on edge cases — often situations of employees on long leave or in international mobility.

The third problem, more structural, concerned governance. HRIS ownership was shared between the HR function and the finance department, without clear arbitration in case of conflict. Functional evolutions were instructed case by case, without consolidated roadmap and without inscription in a multi-year vision.

Intervention

The intervention articulated around three projects conducted in parallel but distinct in their objectives and teams.

The first project, conducted in emergency over two months, aimed to secure monthly payroll. It consisted in mobilizing a consulting firm specialized in double-checking, in reconstituting the documentation of payroll rules and in training an internal cell dedicated to pre-closing controls. The direct cost, significant on the fiscal year, was recorded as exceptional provision.

The second project, conducted over six months, aimed to recover the functional consistency of modules. It consisted in constituting a mixed HR/IT/finance working group, in arbitrating module by module the configuration divergences and in formalizing a single management rules reference. This project revealed several cases of configuration in contradiction with the applicable collective agreement, which were the subject of retroactive regularizations.

The third project, conducted over the entire year, aimed to refound governance. It consisted in formalizing a single HRIS steering committee, chaired by the HR director with systematic presence of the IT director and finance director, in inscribing evolutions in a triennial roadmap validated in executive committee and in instituting a quarterly point before employee representatives on HRIS project progress.

Outcome

At the end of fiscal year 2026, the measured indicators were the following. The payroll anomaly rate had returned to a level conforming to sector standards by the sixth month. The single management rules reference had been stabilized on three modules out of four, the training module remaining under refoundation. HRIS governance had held its quarterly cadence without interruption, and employee representatives had renewed their trust during a session declaration.

Beyond technical indicators, the internal climate had significantly evolved. Informal feedback reaching the HR director reported a restoration of trust in the HR function, after several years of distrust linked to repeated payroll incidents.

Lessons

Three main lessons were formalized by the HR director in a mission closing note, to the attention of the shareholder fund and the executive committee.

The first lesson concerns the necessity to separate the payroll subject from other HRIS projects. Payroll is a separate subject: its failure immediately reaches employee trust and triggers reactions disproportionate to the actual technical volume. As long as payroll is not stabilized, no other HRIS project can be conducted in serene conditions.

The second lesson concerns documentation. The absence of management rules documentation is, in nearly all observed cases, the advanced symptom of a major technical debt. Documentation is an investment with deferred but certain return; its absence is a latent risk whose eruption cost always exceeds, in the end, the initial production cost.

The third lesson concerns governance. The blurred distribution of responsibilities between HR, IT and finance on the HRIS is a recurring cause of degradation. A clear governance, formalized and honored by effective arbitrations, is worth more than a sophisticated governance not respected.
