Compiled by an experienced practitioner in the field, this book contains definitions of the major terms used in Reliability Engineering and Software Assessment. Approximately 2000 definitions have been carefully selected from standards and literature published by leading institutions such as the IEEE and IEC. Alternative definitions of the same term are given where relevant, enabling the reader to compare and contrast, thereby giving useful insights into different aspects of the same term. There is also extensive cross-referencing to make the book easy to use and practical. This book will provide an invaluable reference book for anyone working in the fields of reliability engineering or software assessment but should be of particular interest to industrial researchers and practitioners, members of standards committees, reliability consultants, students on Software Quality courses, technical authors and sub-editors.
