Object-Process Methodology (OPM) is an intuitive approach to systems engineering. This book presents the theory and practice of OPM with examples from various industry segments and engineering disciplines, as well as daily life. OPM is a generic, domain independent approach that is applicable almost anywhere in systems engineering.
Highly recommended! Prof. Dori makes an excellent case for OPM, an alternative to UML in the Systems Design, Analysis and Lifecycle space. An extremely intuitive paradigm that appeals to both our auditory and visual senses by placing real English text alongside clear, unambiguous diagrams. The book is chock-full with examples from Systems Engineering and from life. Very applicable to systems & software professionals. See www.opcat.com for the tool.
Full disclosure: I edited this book which was written by my father. My recommendation is obviously biased, but looking back with my experience I can honestly say that the book is a valuable addition to your bookshelf, and the OPM methodology is an extremely valuable addition to your toolkit.
