Summary: 
The general public is expected to demand in not too distant future instituting more stringent certification procedures for computing parts of traditional and new-generation safety-critical application systems. Such quality-of-service (QoS) certification processes will not and can not rely solely on the testing approach. Design-time guaranteeing of timely service capabilities of various subsystems is an inevitable part of such processes. Although some promising developments in this area have been occurring in recent years, the technological challenges yet to be overcome are enormous. This paper is a summary of the author's perspective on the remaining challenges and promising directions for tackling them.
