A safety-critical system is a system whose failure or malfunction would cause a significant increase in the safety risk for the people and/or environment involved. By definition a system in which any failure or design error has the potential to lead to loss of life. A great example of such is a software which controls surgery robots or a control system for a chemical manufacturing plant.
On the contrary, mission-critical systems are systems whose failure may result in the failure of some goal-directed activity. An example of a mission-critical system may be an online banking system, railway/aircraft operating and control system, electric power system, and many other computer systems that will adversely affect business and society when they fail.
The high price of failure of critical systems means that trusted methods and techniques must be used for development and validation. For critical systems, the costs of verification and validation are usually very high, more than 50% of the total system development costs.
3mdeb engineers are experienced in creating, validating and maintaining critical systems for years. We are focusing on safety assurance and reliability, and we can prove, that the system meets its dependability requirements with specific validation and verification output logs.
Depending on the project charter, we can show detailed arguments and evidence that a certain level of safety or dependability required by a regulator has been achieved and a system can be certified for operational use.
