About Sebastien
Personal, practical, and field-tested.
Sebastien Frionnet has worked more than 30 years on quality, environmental, social, health, and safety systems, first in the private sector and, since 2017, in international development settings.
His approach is grounded in one principle: compliance is rarely a purely technical issue. The real challenge is building systems teams can actually apply under operational pressure.
How Mazuris works
- 1
Map the processes as they actually occur in reality
Start from real site constraints and risk exposure in a collaborative manner in order to capture precisely the process, roles and responsibilities, step by step.
- 2
Integrate new requirements into the process flow
Build concise procedures, checklists, and reporting routines that each responsible person can run consistently. Focus on integrating the compliance requirements with the procedure.
- 3
Trial the revised approach through real case studies
Support the team in testing the revised process on concrete examples, and make the necessary adjustments. Develop capacity of all the stakeholders involved, internally or externally.
