Dynamic System Development Method

Dynamic System Development MethodOriginated in 1994DSDM became the number one framework

for Rapid Application Development (RAD)Most mature agile development methodDSDM is about people, not toolsIt is about truly understanding the needs of

a businessProvides a tool and technique independent

framework

IntroductionDevelops the system dynamicallyIncremental prototypingPreferred to fix time and resources and

then adjust the amount of functionality accordingly

Delivering software solutions that work and delivering them as quickly and as cheaply as possible.

Provides a framework of controls and best practice for Rapid Application Development

Phases of DSDM

1) Pre-ProjectCandidate projects are identifiedProject funding is realizedProject commitment is ensured

2) Project Life-cycle

Study

Functional Model Iteration

Identify functional prototype

Agree schedule

Feasibility Study

Business Study

Create functional prototype

Review functional prototype

2) Project Life-Cycle

Design and Build Iteration

Implementation

User approval and guidelines

Train users

Identify design prototype

Agree schedule

Implement

Review business

Create design prototype

Review design prototype

3) Post-Project

Ensures the system operating effectively and efficiently

The maintenance can be viewed as continuing development based on the iterative and incremental nature of DSDM

Maintenance, enhancements and fixes to the project according to DSDM principles

9 Key PrinciplesUser involvementProject team must be empowered to make

decisionsA focus on frequent delivery of products

deliver "good enough" earlier is always better than to deliver everything "perfectly" in the end

Delivering a system that addresses the current business needs

Development is iterative and incremental and driven by users’ feedback

9 Key PrinciplesAll changes during the development are

reversibleThe high level scope and requirements

should be base-lined before the project starts

Testing is carried out throughout the project life-cycle

Communication and cooperation among all project stakeholders is required

Critical Success FactorAcceptance of DSDM by senior

management and other employeescommitment of management to ensure

end-user involvementProject Team

Skillful membersStable unionEmpowerment of the project teamRight technology to conduct the project

Supportive relationship between customer and vendor is required

Related Methods and QualityThe DSDM project framework is

independent of, and can be implemented in conjunction with, other iterative methodologies such as Extreme Programming and the Rational Unified Process

Introducing DSDM will help CMM level 1 organizations to achieve level 2

Concepts of DSDM can improve XP with a robust requirements and project management mechanism

Model AdvantagesActive user participation throughout the life

of the project and iterative nature of development improves quality of the product.

Ensures rapid, effective and maintainable deliveries which match the needs of the business better

Both of the above factors result in reduced project costs

Model LimitationsDSDM is a relatively new modelIt is not very common. So it is difficult to

understandlike with many other structured

approaches, the relatively high barrier to entry (apart from the licensing costs)

Switching to DSDM is neither cheap nor fast, and requires a significant cultural shift in any organization
