Dynamic systems development method DSDM is an agile project delivery framework, initially used as a software development method. DSDM fixes cost, quality and time at the outset and uses the MoSCoW prioritisation of scope into musts , shoulds , coulds and will not haves to adjust the project deliverable to meet the stated time constraint. At the same time the new DSDM manual recognised the need to operate alongside other frameworks for service delivery esp. The user interfaces for software applications were moving from the old green screens to the graphical user interfaces that are used today. New application development tools were coming on the market, such as PowerBuilder. These enabled developers to share their proposed solutions much more easily with their customers — prototyping became a reality and the frustrations of the classical, sequential waterfall development methods could be put to one side.

As an extension of rapid application development, DSDM focuses on information systems projects that are characterised by tight schedules and budgets.
DSDM addresses the most common failures of information systems projects, including exceeding budgets, missing deadlines, and lack of user involvement and top-management commitment.
In order for DSDM to be a success, there are 9 instrumental factors which need to be met. If these cannot be met, it presents a risk to the Atern approach which is not necessarily a show stopper but which does need to be managed. These risks are also highlighted by the Project Approach Questionnaire. The post-project phase ensures the system operates effectively and efficiently. This is realised by maintenance, enhancements and fixes according to DSDM principles.
The maintenance can be viewed as continuing development based on the iterative and incremental nature of DSDM. Instead of finishing the project in one cycle usually the project can return to the previous phases or stages so that the previous step and the deliverable products can be refined. This diagram depicts the DSDM iterative development, started on functional model iteration, design and build iteration, and implementation phase. The description of each stage will be explained later in this entry.
Judging by the type of project, organisational and people issues, the decision is made, whether to use DSDM or not. It is used to support the main goals of DSDM to realise the development of an IS on time, within budget and with the desired quality. It is an acronym that stands for:. Prototyping — This technique refers to the creation of prototypes of the system under development at an early stage of the project. This way good user involvement is realised, one of the key success factors of DSDM, or any System Development project for that matter.
In order to realise a solution of good quality, DSDM advocates testing throughout each iteration. Since DSDM is a tool and technique independent method, the project team is free to choose its own test management method, for example Test Management Approach. In a workshop the stakeholders come together and discuss the project.
Modeling — This technique is essential and purposely used to visualise the diagrammatic representation of a specific aspect of the system or business area that is being developed. Modelling gives a better understanding for DSDM project team over a business domain. Configuration Management — A good implementation of this configuration management technique is important for the dynamic nature of DSDM.
Since there is more than one thing being handled at once during the development process of the system, and the products are being delivered frequently at a very fast rate, the products therefore need to be controlled strictly as they achieve partial completion. There are some roles introduced within DSDM environment.
It is important that the project members need to be appointed to different roles before they start to run the project. Each role has its own responsibility. The roles are:. Within DSDM a number of factors are identified as being of great importance to ensure successful projects. This ensures that the different actors of the project are motivated from the start and remain involved throughout the project.
Factor 4: Finally DSDM also states that a supportive relationship between customer and vendor is required. This goes for both projects that are realised internally within companies or by outside contractors. An aid in ensuring a supporting relationship could be ISPL. The DSDM Consortium was founded in by an association of vendors and experts in the field of software engineering and was created with the objective of jointly developing and promoting an independent RAD framework by combining their best practice experiences.
