As relationship marketing research evolved, a number of key constructs emerged. Some scholars have argued that these constructs are not conceptually or empirically distinct. We investigate this phenomenon based on the premise that sustained research effort towards studying conceptually overlapping/redundant constructs, while treating them as independent, can hamper the development of the field. We use prototyping, a method adopted from psychology, to examine consumers’ views of these constructs, and then identify relationship contexts where constructs are distinct or redundant.

SYSTEMS engineering, RAPID prototyping, DEFENSE industries, MANUFACTURING processes, and LIKELIHOOD ratio tests
In 2007, John Young, then-Under Secretary of Defense for Acquisition, Technology and Logistics, mandated the use of "competitive prototyping" strategies in defense acquisition. Further, Department of Defense Instruction 5000.02 includes considerations for prototyping in the acquisition strategy. A 2017 memorandum circulated by Young lists five prototyping benefits, which are expected to "reduce technical risk, validate designs, validate cost estimates, evaluate manufacturing processes, and refine requirements." However, a process to assess whether, and to what extent, a prototype will be or has been successful in achieving these benefits is not currently in use by the Department of Defense. Because cost increases and schedule extension downsides are inherent in prototyping, such an assessment is critical. This research proposes an approach for assessing the likelihood of achieving expected prototyping benefits based on identifying the factors yielding these benefits as well as their relative weights.

ECONOMIC impact, RAPID prototyping, PRODUCT design, RESEARCH & development, INNOVATIONS in business, and ENGINEERING students
Abstract: Research and development laboratories in universities and firms around the world try to maximize innovation with a limited set of resources. However, questions remain about the influence of resource constraints on idea generation in early-stage product design. Multiple embedded case studies were conducted with engineering students and faculty at two university campuses in Mexico. Students developed sketches for products that would satisfy an open-ended design problem in a constrained-resource setting, where the variables were the timing of when information about these constraints was revealed, and the regular prototyping environment of the student. The evidence suggests that the timing of awareness of constraints can have an impact on design outcomes, but that this effect varies depending on the designer's regular prototyping resource environment.

TECHNOLOGICAL innovations, COMMAND of troops, MILITARY technology, and DISRUPTIVE technologies
The Department of Defense (DoD) has recently launched several initiatives to accelerate technological innovation and sustain the U.S. military's technological leadership in an environment of increasing global competition. These include six new or expanded programs to enhance the use of experimentation and prototyping under the Office of the Secretary of Defense and the military services. This study examines the six programs and compares their features in light of historical case studies of past disruptive military innovations and the success factors that enabled these innovations to progress from idea to prototype to fielded military capability. Best practices are identified that can be shared between the six programs, or implemented in the design of new DoD initiatives to promote and secure U.S. technological dominance on the battlefields of tomorrow.

In order to investigate how the use of robots may impact everyday tasks, twelve participants in our study interacted with a University of Hertfordshire Sunflower robot over a period of 8 weeks in the university's Robot House. Participants performed two constrained tasks, one physical and one cognitive, four times over this period. Participant responses were recorded using a variety of measures including the System Usability Scale and the NASA Task Load Index. The use of the robot had an impact on the experienced workload of the participants diﬀerently for the two tasks, and this eﬀect changed over time. In the physical task, there was evidence of adaptation to the robot's behavior. For the cognitive task, the use of the robot was experienced as more frustrating in the later weeks.

RAPID prototyping, PROTOTYPES, SOFTWARE engineering, COMPUTER software development, USER interfaces (Computer systems), and SYSTEMS design
Prototyping, a method and technique frequently used in many engineering disciplines, has been adopted as a technique in software engineering to improve the calculation of new projects involving risks. However, there has so far been a lack of documented experience with the use of prototyping in industrial software production. The present work tries to close this gap. First, we introduce central prototyping concepts and terminology. In the subsequent section we present five industrial software projects in which explicit use was made of prototyping. Based on our analysis of these projects we present the resulting conclusions: prototyping means more than rapidly developing user interfaces; prototyping is a central part of a development strategy; prototyping means end user involvement; finding the right mixture of prototypes improves the development process.
