The OHI Methodology
A structured, phase-based approach to operational hygiene
The Operational Hygiene Index is built on a clear, repeatable methodology. Every engagement moves through a defined sequence of phases, each one sharpening the picture from the phase before it. Depending on your situation, the phases combine differently, but the underlying structure stays the same: understand, investigate, and build a roadmap you can act on.

Phase 1
Kick-off
Define your starting point. In a structured session, we capture your site's production processes, equipment, and current hygiene challenges. Choose the standard remote kick-off, which sets the stage for the questionnaire and audit phases that follow, or the extended kick-off with on-site audit, where we gather data in real time and identify hygiene gaps directly at your facility. Either way, this foundation shapes everything that follows.

Phase 2
Questionnaire
Dig deeper with tailored surveys covering the specific systems and processes relevant to your site, from pump and pigging line inventories to cleaning procedures. Because we already know where to look, thanks to your kick-off, these questionnaires deliver the granular data needed to sharpen the audit findings and the roadmap that follows.
Phase 3
Audit
Two days on-site to investigate areas most facilities overlook. We examine your microbiology, process engineering, and facility-specific conditions, and deliver initial concrete recommendations, both direct measures and first ideas on necessary tools and process structure. Full detail on sampling strategy and process landscape follows in the evaluation of the three phases. If you started with a standard kick-off, this phase follows naturally after the questionnaire.
