It both blends and blurs the lines between science and engineering, and requires a risk‐based, disciplined, and graded approach to effectively manage scope, cost, and complexity of the final product. Many leaders, program managers, and scientists are unwilling to involve systems engineering because of the perception that systems engineering is heavily process oriented, adds unnecessary costs, and should be applied only to mature technologies. The value of systems engineering as applied to ESR&D is unclear to these key individuals. The unfortunate result is that system engineering is not applied to ESR&D. This results in R&D efforts that may have solved the wrong problem, selected the wrong architecture, require technical rework, have difficulty transitioning later maturity levels, and result in higher R&D costs and extended development timelines. This article discusses the difficulty of introducing systems engineering to the research and early development process and their inclination perspectives of researchers, engineers, and managers. The article shall offer potential means to manage the cultural transformation of early adoption of right‐sized systems engineering in ESR&D and reverse the attitudinal positions.

The summative system owes its capabilities to the summation of the characteristics and sub-capabilities of its elements. The constitutive system has capabilities greater than the summation of its elements. The constitutive system concept demonstrates a potential need to shift the traditional systems engineering focus to address the problems of multiple integrated complex systems for which a final solution is not necessarily the end expectation. The objective involves 'satisficing' a holistic system. By examining the auto battle management aid (ABMA) case study, we conclude that dynamic and static doctrines provide us with an opportunity to observe a newly developed management framework. The goal includes creating a framework that would allow us to effectively 'satisfice' the management demands of an ever-changing SoS environment.

Additionally the integration of multiple independent systems increases the management challenge. A System of Systems (SoS) has unique attributes which bring about unique management challenges. Architecture frameworks exist to organize and manage information about an architecture, and can be used to manage SoS architecture. One proposed approach was a framework that spans from component to enterprise, where enterprise is a SoS. A potential problem for this approach is that the lower half of the framework (from system down), is constructed using a reductionist approach while the upper part of the framework is constructed using a composition approach—that is, it is constructed by combining systems to make the broader enterprise system or SoS. So, does it stand to reason that the management approach for systems development should be the same as for SoS development? This article addresses some of the reasons why they should be managed differently, and offers a methodology for implementing the widely accepted Zachman Framework to facilitate the managing of SoS architectures.

Reproducible and scalable fabrication of NV-ensembles with desired properties is crucial. This work addresses these challenges by developing a chemical vapor deposition (CVD) synthesis process to produce diamond material at scale with improved NV-ensemble properties for a target NV density. The material reported in this work enables immediate sensitivity improvements for current devices. In addition, techniques established in this work for material and sensor characterization at different stages of the CVD synthesis process provide metrics for future efforts targeting other NV densities or sample geometries.

We have chosen to extend and modify the Zachman Framework (ZF) (Zachman, 1987) because it provides various artifacts needed to describe an information system as viewed by different stakeholder's perspectives of the system. Through the modification and extension of the Zachman Framework, an SoS engineering methodology emerges that enables the management of constituent systems and the SoS that is functionally dependent upon the SoS attributes. Systems and System of Systems There are numerous definitions of a system. INCOSE defines a system as an integrated set of elements that accomplishes a defined objective. These elements include products (hardware, software, and firmware), processes, people, information, techniques, facilities, services, and other support elements (INCOSE, 2006). Buede defines a system as "a set of components (subsystems, segments) acting together to achieve a set of common objectives via the accomplishment of a set of tasks" (Buede, 2000). For the purposes of this article, we will consider a system as something that has the ability to perform a set of tasks to satisfy a mission or objective. For example, an automobile can move a person from one location to another and is a system. The motor with the automobile cannot perform a goal by itself. Removed from the automobile and placed on the ground, it does nothing until it is combined with other parts of a system, e.g. a fuel delivery element, can it work in concert with those other parts to perform the goal of moving an individual to another location. This is not to minimize the complexity or importance of the motor. It is simply a subsystem of a broader system. The same holds true for the fuel delivery subsystem. It is an important part of the automobile, but is a subsystem in the automobile. There are numerous definitions of SoS. INCOSE defines an SoS as "a system-of-interest whose system elements are themselves systems; typically these entail large scale inter-disciplinary problems with multiple, heterogeneous, distributed systems" (INCOSE, 2006). The various definitions of systems do not provide a detailed enough taxonomy to provide differentiation resulting in a dual perspective of a system-of-interest is my element versus your system. This perception extends to your system is my SoS, resulting in sufficient discussion on differentiating elements and systems (Simon, 1962; Koestler, 1967; Boardman, 1995; Simon, 1996). Koestler (1967) managed this perceptual challenge with the introduction of holons-nodes on a hierarchic tree that behave partly as systems, or as elements, depending on how the observer perceives them. In this model there are intermediary forms of a series of levels in an ascending order of complexity. These levels are considered subsystems that have characteristics of the system Processing Note.

Reproducible and scalable fabrication of NV-ensembles with desired properties is crucial, as is an understanding of how those properties influence performance. This work addresses these issues by characterising nitrogen-doped diamond produced by the chemical vapour deposition (CVD) method across a range of synthesis conditions. This is shown to produce material with widely differing absorption characteristics, which is linked to the level of defects other than substitutional nitrogen (NS) and NV. In such material, the achievable concentration of NV− ([NV−]) is found to be influenced by the as-grown properties. At the 10–20 ppm level for [NS], the production of CVD-grown material with strain levels sufficient not to limit achievable device sensitivity is demonstrated and a favourable product of [NV−] and T 2 * is obtained. Additionally, reproducible properties over a batch of 2...
