Quaternaire

What Quaternaire does

Quaternaire is a French management consulting firm founded in 1986 in Nantes by 8 associates and now headquartered in Paris, with regional offices in Orvault/Nantes, Lyon, and Toulouse (the most recent, opened in 2022). The firm targets executives (dirigeants) of French ETIs and large enterprises — both domestically and internationally — to deliver multi-year organizational transformations.

Its service model is structured as an integrated triptych: Conseil (consulting) across five productized lines (organizational transformation, management and leadership, vision/engagement, operational and industrial performance, and commercial performance / customer experience); Formation (training) delivered through the Qualiopi-certified subsidiary Quaternaire Formation, covering management, industrial performance, and services performance; and Accompagnement opérationnel individuel (typically 6–8 individual in-situ coaching sessions) to anchor new managerial behaviors. The firm operates as a pure professional services business with bespoke, quote-based pricing and no public rate card; engagements are multi-year and sold through a direct enterprise field-sales motion supported by thought-leadership content, an annual Paris event (Les Rendez-vous du Management), webinars, and matinales industrielles.

Technology underpins the methodology rather than the offer: the proprietary monQuotidien™ platform objectifies how client teams spend their time; the ROP framework (Rôles – Objectifs – Principales activités) clarifies executive committee responsibilities; AIC (Animation à Intervalle Court) and process-mining-based diagnostics drive operational excellence. A strategic partnership with Fabriq extends these capabilities into digitalized short-interval management rituals at client industrial sites. AI is positioned as one of four operational efficiency levers, with applied use cases in client email automation, appointment preparation, and behavioral analysis on CRM/HR data.

Core offering

Quaternaire is a French management consulting firm that helps executives of ETIs and large enterprises succeed in organizational transformations by combining Conseil (consulting), Formation (Qualiopi-certified training), and Accompagnement opérationnel individuel (on-the-job individual coaching) as a single integrated triptych. The firm delivers multi-year mandates that span strategic vision co-construction, leadership and management development, operational and industrial performance improvement, commercial performance, and customer experience — anchored by the proprietary monQuotidien™ activity-measurement tool and the ROP executive-committee clarification framework.

Product overview

Quaternaire is a French management consulting firm (not a software vendor) organized as an integrated triptych — Conseil (consulting) / Formation (training) / Accompagnement opérationnel individuel (on-the-job individual coaching) — addressing organizational transformation from the CODIR down to the field. Conseil is the core offering, delivered through five productized lines: Transformation organisationnelle, Management et leadership, Vision sens & engagement collaborateur, Performance opérationnelle & industrielle, and Performance commerciale Expérience et parcours client. Formation is delivered under the dedicated Qualiopi-certified entity Quaternaire Formation, structured around three programs (Management & leadership, Performance métiers – Industrie, Performance métiers – Services), with two sub-products "Formation en relation client" and "Manager la relation client". Accompagnement opérationnel individuel (typically 6 to 8 individual sessions in the work situation) anchors the methodological frameworks. Two proprietary assets cut across the portfolio: the monQuotidien™ measurement tool, used to diagnose where time is actually spent, and the ROP method (Rôles – Objectifs – Principales activités) for CODIR clarity. The firm deploys the Fabriq partner platform for digital performance animation (AIC) and wraps all of this in a strong sector specialization (Industries, Banque et assurance, Agroalimentaire, Services & Distribution, Chimie-Pharmaceutique-Cosmétique, Transports & Logistique). Supporting media products (La Revue Quaternaire, Les Rendez-vous du Management, Les Matinales industrielles) animate the firm's editorial and event presence.
