This book is developed as a scientific observation and description of all generalized engineering systems, in terms of what is needed to characterize them and in turn what must be considered in designing them. Chapters 1- 4 provide an extensive outline (and theory) of what all technical systems have in common, and what design considerations make these technical systems suitable for use within industry and within daily life. These concepts are appropriate for students of any branch of engineering. Chapters 5 - 8 translate the insights of the preceding chapters into suggested approaches to the systematic design of systems. Problem solving techniques and open ended problems are introduced.
