Systems engineering process
Published in Lawrence A. Klein, ITS Sensors and Architectures for Traffic Management and Connected Vehicles, 2017
Systems engineering is an interdisciplinary approach utilized to develop and build complex systems such as intelligent transportation and traffic management systems. It focuses on understanding and defining customer needs and functionality early in the development cycle, documenting requirements and system design options, selecting a system design option as part of a review process, and only then proceeding with the subsystem and component-level design and build phases followed by testing and system validation. Systems engineering takes into consideration the points of view of all the stakeholders, that is, the owners, operators, managers, maintainers, and users of the system. A concept of operations (ConOps) is a vital part of the systems engineering process as it is the narrative that conveys the functioning and benefits of the system to each of the stakeholder classes. System design and operation are evaluated through performance measures that compare performance with expected benefits.
The practice of Engineering Psychology – a UK approach

Amplifying the statement of the last bullet point, some examples are given. A CONcept of OPerationS (CONOPS) document, usually produced for military systems to describe their intended purpose and capability, must be suitable as a medium for discussion between the engineering management of the design contractor and the customer. A Mission Analysis, depicting the interactions of mission elements, must be understandable to both systems engineers, and representatives of the system operators, and contribute to their modelling of the system. Task Analysis of operator tasks must be in a form understandable by the particular engineers assigned to the subject area whether they be Software, Hardware, Systems, or Test. These latter emphases on form often requiring that the task analysis be modelled to examine the outputs of task performance at operator or maintainer activity levels.
Designing for Resilience
Published in Ron Burch, Resilient Space Systems Design: An Introduction, 2019
As discussed in Chapter 1, the architecture of a system is directly related to the means by which capability is delivered to its users. It is therefore appropriate to begin with the system architecture when considering how to bolster system-level resilience. Often the process begins when one or more competing architectures have been developed and all credible threats have been identified and characterized. The system's concept of operations (CONOPS) have also been established, meaning that the way in which the system is operated is understood. Prior to the start of the design process, a specification or goal for the maximum allowable cost and the minimum system performance and resilience have been established.
Remote physiological monitoring in a Mars Analog field setting

To determine such capabilities and ensure that they are optimally designed for an interplanetary mission, various technologies and methodologies are evaluated within Mars analogs on Earth. Not only specific technologies, but determinations of concepts of operations (ConOps) and detailed mission architectures, need to be developed to minimize mission risk. This allows for the testing, refinement, and redesign of these capabilities before they are implemented in an environment as extreme as Mars. NASA’s Biologic Analog Science Associated with Lava Terrains (BASALT) research program is one such analog.
