Design error is an important issue in any engineering field and is ubiquitous. In a 60 year career, and over 100 design projects, the author never experienced a design result that was error free. This volume is an introduction to a four volume series on engineering design error intended to describe the types of error, their causation, how to avoid them, and how to detect and remove them. The first chapter establishes the importance of design error, which is shown to be responsible for the majority of major hazards accidents and to be a major contributor to costs due to rework and recall of products.The volume considers the creative process, an the errors that can arise in the envisionment of design, particularly the topic of overlooked aspects. Different types of design activity are described, and the error types and error causation arising in each.Specification is a frequent cause of fundamental problems in design, including omissions in necessary information, contradictions and incompatibilities and the problems of scope creep. The problems of compliance with legal and standards requirements are also described.Organisational problems, such a competing objectives, communication problems in silo organisations and lack of or loss of corporate knowledge.The volume concludes by describing the procedures and methods for quality control of design, some of them traditional and some made possible by recent advances in computer aided design.All topics in the volume are illustrated with practical examples, many from the author’s own experience in leading design review teams, in safety management auditing and in accident investigation.

This volume describes method which can be used to prevent design errors from arising. The principles and approaches to error avoidance are described including improvements of the design process, improvements in knowledge availability, and improvements in communication.Computer aided design has become a major tool in preventing some kinds of error. Especially modern 3D object based design allows greater understanding, and investigation of detailed feature of designs can be odeled. Computer aided design has also introduced new ways for committing them. Simulation, including the use of digital twins, has become a major tool in checking for error in some disciplines, and examples are given of its use. The problems in achieving model fidelity, coverage of a full range of failure possibilities, and selection of challenges to test the simulation moded, remain as issues.The human machine interface is also an important area for errors and weaknesses, and current guidance on HMI design is described. This is largely based on ergonomic and interface design requirements for nuclear reactors, but application to other industries is described.There is a range of design principles, such as avoidance of single point failures, which are described and illustrated in the volume. All of these have been tried and tested in practical projects.With the prevalence of errors in initial design, design success is often dependent on effective design review. Methods for design review are describedChange is generally necessary for any design, bot as designs are integrated, during construction or production, and in actual operation. Changes must be managed, otherwise they themselves can be a cause of failure. The importance of, and methods for, management of change are described.
