NASA Systems Engineering Handbook ○ 279 Use of Correct Terms The requirement uses consistent terminology to refer to the product and its lower level . Are requirements written so that ripple effects from changes are minimized (i.e.
An important aspect of system engineering is converting user "needs" into clear, . There are a number of terms to be avoided in writing requirements, because.
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over.
For example, the requirement: is written in the ubiquitous format, but is, in fact, driven by an unwanted behaviour. The purpose of the system requirements analysis process is to transform the stakeholder, user-oriented view of desired services and properties into a technical view of the product that meets the operational needs of the user. For a format standpoint I usually put conditional phrases at the end of the requirement, Systems Engineering written terms. On the other hand, it differs in that the design-and-delivery phase has a greatly narrowed scope rather than an enormously bloated one. Users from across the life cycle should be included to ensure that all aspects of user needs are accounted for and prioritized. 9 Laws of Systems Engineering
