The requirements specification is undoubtedly the most important document in a project. All too often critical requirements are missing, and mainly quality requirements. The result is an incomplete or faulty design. Nobody can write a "perfect" requirements specification, stating all functionality and quality requirements, so it is crucial to agreements on change control and acceptance criteria in the contract.
Bjørn Runge, EE MSc., Ph.D., EWICS TC7, is Section Manager at Dansk Data Elektronik A/S, a danish company producing computers and software systems. His main areas of work are quality management, development methods, teaching requirements specification and document inspection. He was quality manager at Søren T. Lyngsø A/S for seven years. He is an external quality auditor at Dansk Standard, certifying quality systems mainly in software companies (ISO 9001). He has been a programmer since 1959, and independent software and quality consultant since 1975 in his own company Runge-data.
This tutorial gives an introduction to the techniques of computer security and the management of computer security in commercial and industrial installations. It covers:
This tutorial discusses the management processes required to operate and maintain the safety critical systems on a continuous process plant once it is in beneficial production. An important consideration is the safety culture of the company and how this is reflected in the safety policies and safety procedures for the safe management and operation of the safety systems. The other important area to be considered is the management of preventative ,breakdown and modifications to the safety critical systems including failure, action reporting, upgrades and reconfigurations of the systems.

The IEC (International Electrotechnical Commission) is a world wide organisation promoting international standardisation and co-operation in the electrical and electronic fields.
Computer-related systems are being used widely to perform safety functions. If computer system technology is to be effectively and safely exploited, it is essential that those responsible for making decisions have sufficient guidance for the safety aspects.
IEC International Standard 1508 (Functional Safety of Electrical / Electronic / Programmable Electronic Safety-related Systems) has been developed to set out a generic approach for ensuring the safety of programmable systems. This standard proposes an overall safety lifecycle for both hardware and software. It addresses all stages from initial concept, through design, implementation, operation and maintenance to decommissioning, of a programmable electronic system used to achieve safety. A risk-based approach is adopted to de
