Version 3 of the INCOSE Systems Engineering Handbook represents a shift in paradigm toward global industry application consistent with the Systems Engineering Vision. Developed for the new systems engineer, the engineer in another discipline who needs to perform systems engineering or the experienced systems engineer who needs a convenient reference, the handbook provides an updated description of the key process activities performed by systems engineers.

The descriptions in this handbook show what each systems engineering process activity entails, in the context of designing for affordability and performance. On some projects, a given activity may be performed very informally (e.g., on the back of an envelope, or in an engineer’s notebook); on other projects, very formally, with interim products under formal configuration control. This document is not intended to advocate any level of formality as necessary or appropriate in all situations.

Members may download both version 3.1 and version 2a of the Systems Engineering Handbook from the product area of INCOSE Connect. There is no charge to members for softcopy. Members and the general public may purchase a hardcopy version from the INCOSE Office.
