Safety Analysis Activities (FMEA, FMEDA, DFA, FTA) for ISO 26262 Compliant Solution Development

As part of ISO 26262 services, we help our customers with a wide range of safety analysis activities like HARA, FMEA, FMEDA, DFA, FTA, FMECA and more.

Our team of ISO 26262 experts and automotive domain veterans have partnered with global Automotive OEMs and Suppliers to deliver cutting-edge solutions for lighting system, electronic power steering, Seating Control, Powertrain ECU and so on.

We provide support for safety analysis activities across the safety lifecycle- Concept, Software, Hardware and System. 

Proven Competency in Safety Analyses Required for ASIL Compliance

  • It is a top down approach where engineers first consider a fault in a component and then analyse the effects
  • Failure Mode and Effects Analysis (FMEA) is an example of inductive analysis
  • Inductive Analysis is required for all ASIL Levels (ASIL A to ASIL D)

Inductive Anlysis-1

  • It is a bottom up approach where a system failure is identified followed by the component and its state that led to the failure
  • Fault Tree Analysis (FTA) is an example of deductive analysis
  • Recommended for ASIL B and required for ASIL C and ASIL D

Inductive Anlysis-1

  • Analysis based on qualitative aspects of failure performed by individual experience and past history of faults
  • Examples are FMEA and DFA (Dependent Failure Analysis)


  • Involves certain metrics such as Single Point Failure Metrics, Latent Failure Metrics and PMHF for estimating failure rates
  • FMEDA and Quantitative FTA are commonly used Quantitative Analyses
