Inserting Safety into Software – Safety Critical Systems – Management Perspective
Keywords:
Safety-Critical Systems, Software Safety, Software Quality, Road Traffic Control System (RTCS).Abstract
Organizations are more interested in delivering
the software product within a limited time frame with more profitability. Hierarchical positions in the organization, from top to bottom define constraints for non-disclosure of information in view of the safety of the entire organization, resulting in poor flow of information, causing incomplete understanding of the desired safety measures, at the lowermost level. Mere understanding the problem by the peer does not ensure understanding the degree of severity and importance of the software care, needs to be flown to the bottom level of software development personnel with magnificent visualization and illustration. The developing team would be under pressure for delivering the ultimate product under compelling reasons, causing negligence or ignorance to critical issues involved, thereby
exposing the problems, during software implementation. Software development team has incomplete knowledge of safety and organization has incomplete knowledge of software behavior and its life cycle. This paper proposes integrated typical structure of information flow and reviews in a cyclical way for continuous evaluation and validation through specialized team for developing safety critical software.
Software Safety greatly depend on adequate salient information flows, with detailed consequences of failures and their effects, down to developmental team, and their characteristic importance of assignment. Organization behavior and software safety though both are independent but are of intricate nature having effects on both sides, such as software behavior and
organization safety on the other hand. Thus neither of these should be ignored. In this paper we critically analyze various organizational factors and software safety factors having interaction between them. An amalgamated design is suggested in between these independent domains. This model is applied to
laboratory prototype of RTCS (Road Traffic Control System). The results have inferred that all safety critical operations were safe and risk free, adequate to handle contingent situations arising out of practices.
