Mock-up

Hailing from the English term mock-up or mockup (also Maquette ) denotes, for example, a dummy in German. But he will now mostly used for a scaled -made model or a replica for presentation purposes, by contrast, the prototype is a working model. First uses of the term are occupied in the aviation industry. He was later taken over by other areas such as industrial design.

Word origin

Etymologically, the English word was mockup for the first time in 1920 with the meaning of simulation or model proved. The model is used for apparent imitation of the original; so it must look like this ( possibly scaled), but not necessarily work the same way. In fact, the root word had mock since the middle of the eighteenth century, the connotation of a mocking imitation of get ( See: Mockturtlesuppe or Mockingbird ). Originally, the word is not related to the Imitation, but only to the Taunt: So it meant in the Middle Ages Mocking based on double mocquer, just mock mock. In modern high German is " mock " to date, the reflexive verb used when someone expresses something about mocking or derogatory.

Use of the term

Capital and consumer goods industry

Especially in aviation is a mock-up for the production of non-functional (not airworthy ) models. These often are test objects for various function tests or the interior, or demonstration models for trade shows that are already intended to give an impression of the appearance of the aircraft to prospective customers.

A further development provides digital mock-up represents the volume models of various 3D CAD programs are assembled and tested as a digital prototype. The phase of prototyping is thus reduced.

Software Development

A mock -up in software development refers to a rudimentary throwaway prototypes of the user interface of a software to create. Mock -ups are used especially in early development phases in order to determine requirements for the user interface in collaboration with the client and users better. It usually is a pure backbone of the controls without further functionality. Often no programming takes place, and instead they create in an image editing program.

So-called Mock objects are used for testing, in particular for module test (English unittest ), testing of individual parts. They serve as placeholders for objects that are needed for the testing of another part, and for example at the beginning of the development are not yet available (see also Test Driven Development - engl Test Driven Development, TDD Abbr. ). Later Mock objects are used, for example when the initialization of the ( existing, functional ) object to productive backend systems impossible or legal reasons (see also Federal Data Protection Act ) is not allowed to elaborate or in a test environment due to lack of connection. Another common reason for using a mock object is a nichtvorhersehbares behavior of the actual class, such as the return of the current exchange rate, or behavior that is shielded due to the object-oriented principle of encapsulation before the caller of the method; This is the case with more recent environments such as J2EE, especially for container functions.

Project Management

A mock -up in project management is a collection of A4/A3-Skizzen the A0 to create plans and is applied at the beginning of the planning process. The project anticipates so that the planning.

Dental Technology

In the manufacture of dental prostheses by dental technology, provides a mock-up that is created using a wax-up ( wax modeling ), a kind of " preview" on the planned end product and thus provide valuable information for the preparation of the definitive prosthesis. It involves temporary acrylic tooth-colored shells that are simply attached to the existing teeth, without having to be ground before. The patient has a mock-up the possibility of its future dentures to assess particularly in terms of aesthetics.
