The benefits of an HR consulting firm

Strategic and operational support to structure and optimize your HR function
External and objective perspective: an HR consultant brings a neutral, expert view of your organization, identifies pain points, and proposes solutions that day-to-day proximity sometimes makes invisible.
Multi-sector expertise: our HR consultants work with companies of all sizes and across all sectors. This diversity of experience enables them to bring you the best market practices.
Flexible engagement: from a one-off assessment to long-term support, HR consulting adapts to your actual needs. You access senior expertise only when you need it.
Transformation accelerator: whether it’s structuring your HR function, leading a QWL project, redesigning your compensation policy, or supporting a reorganization, the HR consultant saves time and secures the process.
Upskilling your teams: beyond the deliverable, the HR consultant transfers methods and tools to your internal teams to ensure lasting results.
Guaranteed confidentiality: for sensitive matters (workplace climate, HR audit, executive coaching), the HR consultant provides an essential framework of trust and discretion.
Our methodology

Why entrust your HR strategy to BoostRH?

1
Listening and assessment: we begin with an immersion phase to understand your organization, culture, business challenges, and priority HR issues.
2
Assignment scoping: together, we define the scope of intervention, expected deliverables, timeline, and success indicators.
3
Analysis and recommendations: our HR consultants carry out an in-depth analysis (HR audit, benchmark, internal interviews) and formulate concrete, actionable recommendations.
4
Operational action plan: we translate recommendations into a detailed, prioritized, and realistic action plan, with the associated resources and timeline.
5
Implementation support: if desired, our HR consultants support you in deploying actions: change management, internal communication, manager training.
6
Review and anchoring: at the end of the assignment, we conduct a shared review and ensure that tools, processes, and skills are firmly embedded in your organization.

Frequently asked questions

Frequently asked questions about HR consulting in Rennes

Why use an HR consulting firm in Rennes?
An HR consulting firm in Rennes provides you with external, objective expertise to resolve your human resources challenges. Whether it's structuring your HR function, improving your workplace climate, ensuring compliance, or supporting a transformation, an experienced HR consultant delivers concrete, measurable results tailored to your company's specific context.
An HR consultant works across the entire human resources function: HR audit and assessment, HR strategy definition, compensation policy and job classification, workforce planning (GPEC/GEPP), quality of work life (QWL), labor relations and social dialogue, labor law advice, executive and manager coaching, implementation of HR tools (annual reviews, HRIS, dashboards).
An HR consulting firm supports you on the strategy and management of your human resources function: organization, processes, tools, compliance, transformation. A recruitment firm focuses on finding and selecting candidates to fill a specific position. Boost'RH offers both services, which allows for comprehensive and consistent support.
The cost depends on the scope of the assignment, its duration, and the level of expertise required. A one-off HR assessment represents a different investment than a multi-month transformation support engagement. Boost'RH systematically provides a detailed quote after analyzing your needs, ensuring a controlled budget with no surprises.
The assignment begins with a listening and assessment phase to understand your challenges. We then formulate concrete recommendations, translated into an operational action plan. If desired, we support you through implementation: change management, training, tool deployment. An end-of-assignment review formalizes the results achieved and next steps.
Yes, Boost'RH has an office in Rennes covering Rennes and the entire area. Our HR consultants work directly at your premises and know the specificities of the economic fabric and employment market in your area. This proximity guarantees responsive, locally-anchored support.
