INCOSE Systems Engineering Handbook v. 3

Preface
Objective The INCOSE Systems Engineering Handbook, version 3 (SEHv3), represents a shift in paradigm toward global industry application consistent with the Systems Engineering Vision. The objective for this document is to provide an updateddescription of the key process activities performed by systems engineers. The intended audience is the new systems engineer, an engineer in another discipline who needs to perform systems engineering or an experienced systems engineer who needs a convenient reference. The descriptions in this handbook show what each systems engineering process activity entails, in the context of designing foraffordability 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. The appropriate degree of formalityin the execution of any systems engineering process activity is determined by: a. the need for communication of what is being done (across members of a project team, across organizations, or over time to support future activities), b. the level of uncertainty, c. the degree of complexity, and d. the consequences to human welfare. On smaller projects, where the span of required communications is...
