The change request management process in systems engineering is the process of requesting, determining attainability, planning, implementing, and evaluating of changes to a system. Its main goals are to support the processing and traceability of changes to an interconnected set of factors.
An engineering change order (ECO), also called an engineering change notice (ECN), engineering change (EC), or engineering release notice(ERN), is an artifact used to implement changes to components or end products. The ECO is utilized to control and coordinate changes to product designs that evolve over time.
Within quality management systems (QMS) and information technology (IT) systems, change control is a process—either formal or informal [1] —used to ensure that changes to a product or system are introduced in a controlled and coordinated manner. It reduces the possibility that unnecessary changes will be introduced to a system without ...
Configuration change control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. Configuration status accounting is the ability to record and report on the configuration baselines associated with each configuration item at any moment of time.
Literature and engineering practice also suggest a third type of IA, experiential IA, in that the impact of changes is often determined using expert design knowledge. Review meeting protocols, [ 11 ] informal team discussions, and individual engineering judgement [ 12 ] can all be used to determine the consequences of a modification.
Form, Fit, and Function (also F3 or FFF) is a concept used in various industries, including manufacturing, engineering, and architecture, to describe aspects of a product's design, performance, and compliance to a specification.
Engineering for Change; Engineering Ministries International [76] Engineering companies in more developed economies face challenges with regard to the number of engineers being trained, compared with those retiring. This problem is prominent in the UK where engineering has a poor image and low status. [77]
A design change is a modification to the design of a product or system. Design changes can happen at any stage in the product development process [ 1 ] [ 2 ] as well as later in the product or system's lifecycle.
