AbstractExtensive work exists on value in multiple domains. However, there are different interpretations, highlighting a lack of clarity about the fundamental characteristics. To address this, we present seven value axioms resulting from inductive research. The axioms may be viewed as general rules describing value in any context, therefore conveying the fundamental characteristics of the phenomenon. They reveal that value is: (1) connected to people; (2) an output of a cognitive process; (3) in requirement of a determination process; (4) a matter of a given situation; (5) determined by the interpretations of entities; and related to (6) entities and (7) criteria. The nature of value is of particular importance to the design community, given the emphasis on value in design and product development. In this context, a lack of clarity may be perceived in terms of when value appears, appropriate metrics, and how to add value. To provide explanations, there is a need for a theory of value in design. The presented axioms may provide the basis, as they are fundamental statements on the nature of value and not limited to a specific domain. We highlight theory requirements based on the axioms.

Abstract The objective of this paper is to elucidate the variables that govern coffee extraction from single serve coffee capsules. The study was conducted on 43 Nespresso and Nespresso-compatible capsules of the same geometry, from all of which the coffee was extracted on the same machine. This allowed the link between a range of coffee and capsule (input) parameters with coffee brew (output) variables to be studied. It was demonstrated that the most efficient way to increase total dissolved solids in the brew is to use more coffee for extraction, and/or to grind the coffee more finely. However, grinding too finely can lead to excessive flow restriction. The most significant new insight from this study is the importance of the proportion of fines (particles smaller than 100 µm) regarding the capsule extraction dynamics. Capsules with a higher share of fines, for similar median particle size of the ground coffee, led to longer extraction times. General rules applicable for capsule coffee product development were established, although fine-tuning of parameters for successful capsule coffee extraction remains specific to production line and type of coffee.

Project Based Learning (PBL) is a powerful tool for teaching that helps students to get the best out of their effort in terms of the learning results obtained, even more in studies like university degree studies in engineering. A way of getting even more of this is by means of the adaptation of methodologies from different knowledge areas, because this allows the launch of innovative ways of working with certain guarantees of success from the very first moment, and at the same time to integrate skills from different fields within a shared context. Besides, it helps to put to practice some transversal competences. Here a case is shown of the successful adaptation of the methodology of Systems of Layouts, as used in Graphic Design, to a University Degree of Engineering in Industrial Design and Product Development.
