“Implementation is the realisation of an application, or execution of a plan, idea, model, design, specification, standard or algorithm…“    Source: Wikipedia

Engineers, generally, are mainly concerned with various aspects of functionality (behaviour)…

”Engineers, as practitioners of engineering, are professionals who invent, design, analyse, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost”

Some systems, etc, can be regarded functionally as a Black Box, and so a device, object, or system whose inner workings are unknown; only the ‘stimuli inputs’ and ‘output reactions’ are known characteristics; where implementation detail is hidden…

“In systems theory, the black box is an abstraction representing a class of concrete open system which can be viewed solely in terms of its stimuli inputs and output reactions. The constitution and structure of the box are altogether irrelevant to the approach under consideration, which is purely external or phenomenological. In other words, only the behavior of the system will be accounted for…“

_”Black box theories are theories defined only in terms of their function. The term black box theory is applied to any field, philosophy and science or otherwise where some inquiry or definition is made into the relations between the appearance of a system (exterior/outside), i.e. here specifically the system’s black box state, related to its characteristics and behaviour within (interior/inner)”

The Engineers Equivalent to “Occam’s Razor”…

“Occam’s razor, Ockham’s razor, Ocham’s razor (Latin: novacula Occami), also known as the principle of parsimony or the law of parsimony (Latin: lex parsimoniae), is the problem-solving principle that “entities should not be multiplied beyond necessity”

“It is generally understood in the sense that with competing theories or explanations, the simpler one, for example, a model with fewer parameters, is to be preferred. The idea is frequently attributed to English Franciscan friar William of Ockham (c. 1287–1347), a scholastic philosopher and theologian, although he never used these words. This philosophical razor advocates that when presented with competing hypotheses about the same prediction, one should select the solution with the fewest assumptions, and that this is not meant to be a way of choosing between hypotheses that make different predictions”

“Similarly, in science, Occam’s razor is used as an abductive heuristic in the development of theoretical models rather than as a rigorous arbiter between candidate models. In the scientific method, Occam’s razor is not considered an irrefutable principle of logic or a scientific result; the preference for simplicity in the scientific method is based on the falsifiability criterion. For each accepted explanation of a phenomenon, there may be an extremely large, perhaps even incomprehensible, number of possible and more complex alternatives. Since failing explanations can always be burdened with ad hoc hypotheses to prevent them from being falsified, simpler theories are preferable to more complex ones because they tend to be more testable”
