In the first type of approach of EUC described above, it appears easier to teach factory workers, for example, how to read dials, push buttons, pull levers, and log results than to teach them the manufacturing process and mathematical models. The current computing trend is to [[simulate]] a console with similar dials, sliders, levers, and switches, which the end user is taught to use. To further reduce end user training, computer consoles all contain components which are shaped, labled, coloured, and function similarly. EUC developers assume that once the end user knows what and how a particular lever works, they will quickly identify it when it appears in a new console. This means that once staff learns one console, they will be able to operate all consoles. Admittedly each console will have new components, but training is limited to those, not the whole console. This approach requires more than just [[Pavlovian]] responses as the console content will have meaning that is of use and power to the particular computing ___domain. That is, there may be training that reduces the time between sensor reading and action (such as the situation for a pilot of a commercial plane) however, the meaning behind the reading will include other sensor settings as well as whole context that may be fairly involved.
Computing of this type can be labelled [[Black_box_%28systems%29|black box]] where trust will be an essential part, behavioral analysis is the name of the game (see [[Duck_test|Duck test]], and there is a disparate (and very, very wide) gap between the ___domain and the computer support ontologies.
In the other type of EUC described above, it has been argued that '''a''' (teaching programming and computing concepts to a ___domain expert (say, one of the sciences or engineering disciplines) and letting the expert develop rules (this type of action can be subsumed under the topic of business rules)) is easier than '''b''' (teaching the intricacies of a complex discipline to a computer worker<!---need to clarify this further, but, for now, read IT/IS-->). '''b''' is the normal approach of the IT-driven situation. '''a''' has been the reality since day one of computing in many disciplines. One may further argue that resolving issues of '''a''' and '''b''' is not unlike the interplay between [[Distributed_computing|distributed]] and [[Centralized_system|centralized]] processing (which is an age-old concern in computing). In this sense of EUC, there may be computer scientists supporting decisions about architecture, process, and GUI. However, in many cases, the end user owns the software components. One thrust related to this sense of EUC is a focus on providing better languages to the user. [[ICAD]] was an example in the [[Knowledge-Based_Engineering|KBE]] context. Of late, this discipline has moved to a co-joint architecture that features advanced interactive ___domain visualization coupled with a complicated API accessed via [[VBA]], [[C++]], and the like. This type of co-jointness is an example of a ___domain tool augmented with non-trivial extensibility.
