===Dynamic systems development method===
[[Dynamic Systems Development Method]] (DSDM)<ref>Dynamic Systems Development Method Consortium. https://web.archive.org/web/20060209072841/http://na.dsdm.org/</ref> is a framework for delivering business solutions that relies heavily upon prototyping as a core technique, and is itself [[ISO 9001]] approved.  It expands upon most understood definitions of a prototype.  According to DSDM the prototype may be a diagram, a business process, or even a system placed into production. DSDM prototypes are intended to be incremental, evolving from simple forms into more comprehensive ones.

DSDM prototypes can sometimes be ''throwaway'' or ''evolutionary''.  Evolutionary prototypes may be evolved horizontally (breadth then depth) or vertically (each section is built in detail with additional iterations detailing subsequent sections).  Evolutionary prototypes can eventually evolve into final systems.

The four categories of prototypes as recommended by DSDM are:
* '''Business prototypes''' – used to design and demonstrates the business processes being automated.
* '''Usability prototypes''' – used to define, refine, and demonstrate user interface design usability, accessibility, look and feel.
* '''Performance and capacity prototypes''' –  used to define, demonstrate, and predict how systems will perform under peak loads as well as to demonstrate and evaluate other non-functional aspects of  the system (transaction rates, data storage volume, response time, etc.)
* '''Capability/technique prototypes''' – used to develop, demonstrate, and evaluate a design approach or concept.

The [[Dynamic systems development method|DSDM]] lifecycle of a prototype is to:
# Identify prototype
# Agree to a plan
# Create the prototype
# Review the prototype
