Dependability & Safety Analyses

Reliability, Availability, Maintainability and Safety (RAMS) are essential for many industries. In addition, in most of the cases, evidences are requested by the Regulations. PMV Groupe realises analyses based on expertise in several contexts.

May I use my vehicle safely? Is my system reliable? Is my network secured? You may rely on us to carry out analysis compliant with your needs and applicable regulations.

Our areas of expertise

PMV Groupe, thanks to PMV Consulting & Services team, has a panel of experts who are familiar with analytical techniques and have technical background in the design of systems including electronic and software.



Examples of safety analysis requested in Aeronautic against Eurocae and SAE standards (ED-79A / ARP-4754A and ARP-4761):
  • Functional Hazard Analysis (FHA) identification of hazards and their criticality at Aircraft or System level. 
  • Safety Analysis (PASA-ASA-PSSA-SSA) assessment of system architecture versus functional hazards, DAL assignment. 
  • Common Mode Analysis (CMA) assessment of design to avoid single point failure that may lead to undesired events.
  • Zonal Safety Analysis (ZSA) assessment of installation to avoid local environment upset that may lead to undesired events.


Examples of analysis requested in Aerospace against ECSS standards:
  • Software Failure Modes and Effects Analysis (SFMEA) bottom up analysis starting at code or intermediate design level. 
  • Contingency analysis for recovery of the mission integrity.
  • Human dependability analysis assessment of operations manual and procedures for consistency with dependability analyses.

And more…

  • Safety Management System (SMS),
  • Human Factors,
  • Cyber Security...

Our method, our added value


Our RAMS specialists are the leaders for the analysis. We have the responsibility to drive the analysis, as far as possible with PMV Groupe technical back office, on time and on cost.
If necessary, we may identify the areas where specific skills are necessary and clearly define the perimeter of responsibilities amongst analysis participants.    

Added value

RAMS focal point is autonomous and is used to coordinate various people like system, hardware and software designers. 

Our analysts have, at least, a double competence. Of course as regarding the RAMS methodologies (Reliability, Availability, Maintainability and Safety)  but also a technical knowledge allowing to understand the design and effectively identify the relevant failure scenarios.

Fortified by the synergy of the group's activities, from our expert consultants and our EASA approved Design Organisation, we are aware of the industrial constraints and we may directly interface with Authorities.
