Safety-Critical Systems: The Convergence of High Tech and Human Factors

Safety-critical systems, in the sense of software-based systems used in safety­ critical applications, are 'high-tech'. They are products of modern technology. Their effective, efficient and safe functioning depends not only on the devel­ opment of the right technologies but also on the right use of them. The safety of a system may be compromised not only by faults in the system but also by the use in the first place of an unreliable, unsafe, or unproved technology in its development. The key to
