Mockup

Mockups are part of the military acquisition process. Mockups are often used to test human factors and aerodynamics, for example. In this context, mockups include wire-frame models. They can also be used for public display and demonstration purposes prior to the development of a prototype, as with the case of the Lockheed Martin F-35 Lightning II mock-up aircraft. == Garments ==

Mockups are used in sewing to test patterns and check the fit of garments. They are sometimes also referred to as muslins or toiles because they are often made in cheap, lightweight cotton fabrics. They are used both when drafting patterns, to see if the drafted pattern fits the person it is intended for, and when using commercial patterns, to identify any changes that need to be made to improve fit or for stylistic reasons. Creating a mockup also provides an opportunity to practice making a garment before. If substantial alterations are being made, several mockups may be made, each with increasingly more adjustments. Mockups are often made with speed in mind and are partially unfinished as a result, such as being unhemmed, having unfinished seams (which also allows for adjustments to be made more easily), and having only one of a mirrored element (such as being sewn with only one sleeve). == Consumer goods==

Mockups are used in the consumer goods industry as part of the product development process, where dimensions, human factors, overall impression, and commercial art are tested in marketing research. Mockups help to visualise how all design decisions play together, they are convincing and closely resemble the final product, it can be easily revised rather than much later in the production stage, It also helps in visualisation of package design projects in 3D & speed up approvals. == Furniture and cabinetry ==

Mockups are commonly required by designers, architects, and end users for custom furniture and cabinetry. The intention is often to produce a full-sized replica, using inexpensive materials in order to verify a design. Mockups are often used to determine the proportions of the piece, relating to various dimensions of the piece itself, or to fit the piece into a specific space or room. The ability to see how the design of the piece relates to the rest of the space is also an important factor in determining size and design. When designing a functional piece of furniture, such as a desk or table, mockups can be used to test whether they suit typical human shapes and sizes. Designs that fail to consider these issues may not be practical to use. Mockups can also be used to test color, finish, and design details which cannot be visualized from the initial drawings and sketches. Mockups used for this purpose can be on a reduced scale. The cost of making mockups is often more than repaid by the savings made by avoiding going into production with a design which needs improvement. == Software engineering ==

The most common use of mockups in software development is to create user interfaces that show the end user what the software will look like without having to build the software or the underlying functionality. Software UI mockups can range from very simple hand drawn screen layouts, through realistic bitmaps, to semi functional user interfaces developed in a software development tool. Mockups are often used to create unit tests - there they are usually called mock objects. The main reason to create such mockups is to be able to test one part of a software system (a unit) without having to use dependent modules. The function of these dependencies is then "faked" using mock objects. This is especially important if the functions that are simulated like this are difficult to obtain (for example because it involves complex computation) or if the result is non-deterministic, such as the readout of a sensor. A common style of software design is Service-oriented architecture (SOA), where many components communicate via protocols such as HTTP. Service virtualization and API mocks and simulators are examples of implementations of mockups or so called over-the-wire test doubles in software systems that are modelling dependent components or microservices in SOA environments. Mockup software can also be used for micro level evaluation, for example to check a single function, and derive results from the tests to enhance the products power and usability on the whole. Systems engineering Mockups, wireframes and prototypes are not so cleanly distinguished in software and systems engineering, where mockups are a way of designing user interfaces on paper or in computer images. A software mockup will thus look like the real thing, but will not do useful work beyond what the user sees. A software prototype, on the other hand, will look and work just like the real thing. In many cases it is best to design or prototype the user interface before source code is written or hardware is built, to avoid having to go back and make expensive changes. Early layouts of a World Wide Web site or pages are often called mockups. A large selection of proprietary or open-source software tools are available for this purpose. == Architecture ==

At the beginning of a project's construction, architects will often direct contractors to provide material mockups for review. These allow the design team to review material and color selections, and make modifications before product orders are placed. Architectural mockups can also be used for performance testing (such as water penetration at window installations, for example) and help inform the subcontractors how details are to be installed. == See also ==
