This guide to the realities of commercial life is written for the engineer involved in design, project management or manufacturing. The book gives grounding in the principles of contract law, commercial awareness and negotiation skills. It is written from the engineer's viewpoint rather than for the specialist in law or accounting. The author sees two facets to every contract - the technical and the commercial. The most successful companies are those which recognize the interdependence of the two and which actively help the personnel responsible for each to do the same.
