Dynamic Systems Development Method
Dynamic Systems Development Method (DSDM) 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 may 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 DSDM lifecycle of a prototype is to:
- Identify prototype
- Agree to a plan
- Create the prototype
- Review the prototype

Famous quotes containing the words dynamic, systems, development and/or method:
“Knowledge about life is one thing; effective occupation of a place in life, with its dynamic currents passing through your being, is another.”
—William James (1842–1910)
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
“It is to be lamented that the principle of national has had very little nourishment in our country, and, instead, has given place to sectional or state partialities. What more promising method for remedying this defect than by uniting American women of every state and every section in a common effort for our whole country.”
—Catherine E. Beecher (1800–1878)
