  2. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    Definition of the part via a 3D CAD model rather than via a 2D engineering drawing. Drawings may be printed (plotted) from the model for reference use, but the model remains the governing legal instrument. MBP: measurement between pins: threads, splines, gears (internal, female) (synonymous with MBW) (see also MOP, MOW) MBW: measurement between ...

  3. Process-centered design - Wikipedia

    en.wikipedia.org/wiki/Process-centered_design

    Process-centered design (PCD) is a design methodology, which proposes a business centric approach for designing user interfaces.Because of the multi-stage business analysis steps involved right from the beginning of the PCD life cycle, it is believed to achieve the highest levels of business-IT alignment that is possible through UI.

  4. Interface control document - Wikipedia

    en.wikipedia.org/wiki/Interface_control_document

    An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".

  5. ISO/IEC 29119 - Wikipedia

    en.wikipedia.org/wiki/ISO/IEC_29119

    ISO/IEC/IEEE 29119 Software and systems engineering -- Software testing [1] is a series of five international standards for software testing.First developed in 2007 [2] and released in 2013, the standard "defines vocabulary, processes, documentation, techniques, and a process assessment model for testing that can be used within any software development lifecycle."

  6. Test design - Wikipedia

    en.wikipedia.org/wiki/Test_design

    Entire test suites or test cases exposing real bugs can be automatically generated by software using model checking or symbolic execution.Model checking can ensure all the paths of a simple program are exercised, while symbolic execution can detect bugs and generate a test case that will expose the bug when the software is run using this test case.

  7. Software testing - Wikipedia

    en.wikipedia.org/wiki/Software_testing

    Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the quality of ...

    en.wikipedia.org/wiki/Bolt_circle

    Drawing of 5-hole (left) and 4-hole (right) pitch circles A bolt circle diameter or pitch circle diameter ( PCD ), sometimes simply called bolt circle or pitch circle , is a common term for when a number of screw holes for bolts are evenly distributed with their centers along an imaginary circle with a given diameter .

  9. Functional specification - Wikipedia

    en.wikipedia.org/wiki/Functional_specification

    After this, typically the software development and testing team write source code and test cases using the functional specification as the reference. While testing is performed, the behavior of the program is compared against the expected behavior as defined in the functional specification.
