DSDM

DSDM

• Dynamic Systems Development Method

2
Principles of DSDM

• Active user involvement is imperative.
• DSDM teams must be empowered to make decisions.
• The focus is on frequent delivery of products.
• Fitness for business purpose is the essential
  criterion for acceptance of deliverables.
• Iterative and incremental development is
  necessary to converge on an accurate business
  solution.
• All changes during development are reversible.
• Requirements are base lined at a high level.
• Testing is integrated throughout the lifecycle.
• A collaborative and co-operative approach
  between all stakeholders is essential.

Project Structure

• Starting
• Has a major control point after an initial
  understanding of the project has been gained
  point at which a decision to proceed must be
  confirmed, and the option of abandoning project
  must be considered
• End of the Business Study (with Business Area
  Definition, System Architecture Definition, and
  Outline Prototyping Plan)
• Also has an earlier, less critical, control point
  that is sometimes omitted
• The Feasibility Study (Products Feasibility
  Report, optional Feasibility Prototype, Outline
  Plan)

Project Structure

• Running
• A management stage may consist of a number of
  DSDM timeboxes. The number of stages required
  should be determined by balancing the amount of
  management control needed over the project and
  its risks against the potential overhead of
  managing stage boundaries.
• A stage might be mapped
• To a phase (if all the functional model iteration
  is done before all the design and build
  iteration), or
• To the development of a functional area (where
  the functional model iteration and the design and
  build iteration are done in alternation).
• DSDM Implementation is either simply a part of
  the increment (where this is treated as a single
  stage) or may be treated as one or more stages in
  its own right.

Project Structure

• Stopping
• The project review in DSDM is done in each
  increment
• The key is tailoring the methods to do what is
  needed and no more, since in DSDM incremental
  acceptance has already taken place.
• During early adoption of DSDM, the probability of
  and need for lessons learned information is
  heightened.

General Remarks

• DSDM defines several roles and responsibilities
• DSDM specifies several deliverables, such as the
  project initiation document among others
• Certification in DSDM is highly sought after
  especially in the EU.

7
General Remarks

• DSDM is a non-proprietary agile application
  development methodology for developing business
  solutions within tight timeframes.
• It shortens the clock-speed (and time to market)
  for delivery of core business benefits.
• It's tool-independent .

Conclusion

• Few ideas in DSDM are new best practices are
  synergistically built into the model.
• As a result, people are applying DSDM to projects
  in a wide range of fields, in and outside of
  Information Technology.
• Recent trends are to combine DSDM with PRINCE2 or
  with XP (Extreme Programming),
• Enterprise XP or EXP (a term coined by Mike
  Griffiths of Quadrus) seeks the benefits of
• DSDM's project management framework and business
  focus and
• XP's high efficiency and high quality development
  practices
