Altran expertise

  • Altran provides solutions ranging from advanced systems and requirements engineering to de-risk delivery of technically complex projects.
  • Altran has extensive experience in delivering safety-critical systems. The fact that our approach provides a demonstration of software safety and functionality during the early stages of product development minimises the need for testing late on in the lifecycle. In addition, acceptance and certification are de-risked by using a progressive assurance approach throughout the development process.
  • Altran safety services include delivery and maintenance of electronic safety cases, safety and approvals management, Independent Safety Assessments (ISA) and Notified Body (NoBo) Certification.
  • Altran provides training in Safety Management for the railway industry. Altran Praxis is the leading provider of Yellow Book safety-management courses, has trained over 5,000 railway engineers worldwide, and is one of the few companies accredited to deliver this type of training at global level.
