DSDM (Agile Business Consortium)
Agile delivery with fixed cost and time
DSDM (now branded as the Agile Business Consortium framework) was one of the first formalised agile methods, pre-dating the Agile Manifesto. Its central innovation is "MoSCoW prioritisation" combined with fixed time and cost constraints — scope is the variable, not time or budget. It is widely used in UK government and public sector projects that require contractual certainty alongside agility.
Originally developed as Dynamic Systems Development Method in 1994 by a consortium of UK organisations. Evolved into the DSDM Agile Project Framework (2014) under the Agile Business Consortium.
Use DSDM (Agile Business Consortium) when
- ✓Projects with fixed budgets and deadlines where scope must be negotiated iteratively
- ✓UK public sector or government IT projects that require an approved agile framework
- ✓Organisations needing a governance-compatible agile framework with defined roles and artefacts
- ✓Contracts where delivering agreed business value matters more than delivering every requirement
Avoid it when
- ✗Startups or product companies without a contractual fixed-scope context
- ✗Teams already running Scrum or Kanban effectively — DSDM adds governance overhead
- ✗Projects where the customer cannot commit to active involvement throughout delivery
Key Concepts
Must Have, Should Have, Could Have, Won't Have — a prioritisation technique for managing scope within fixed time/cost.
Fixed time periods (2–6 weeks) within which a team delivers the highest-priority scope. Time does not flex; scope does.
A senior stakeholder with authority to make business decisions on behalf of the customer. Must be engaged throughout.
Products are built incrementally, with each iteration adding to a tested and potentially deployable baseline.
Pre-delivery phases that de-risk the project before iterative development begins — a governance checkpoint.
The DSDM equivalent of a product backlog, structured around business value and MoSCoW prioritisation.
How it works
Brief phase to assess whether the project is viable: technically, commercially, and in terms of available team capability.
Establish a shared understanding of the business problem, solution approach, and project governance. Produces the Prioritised Requirements List.
Iterative timeboxed development cycles. Each timebox delivers working software reviewed by the Business Ambassador.
Formal release of the solution to users. Includes training, operational handover, and benefits review.
Tools that support DSDM (Agile Business Consortium)
Industry standard for software development teams — most PMs will encounter Jira in their career
Exceptionally intuitive and visually clean interface — one of the lowest onboarding friction tools for non-technical teams
Highly visual and intuitive interface with color-coded boards — one of the easiest PM tools for non-technical teams to adopt
All-in-one platform replacing multiple tools — docs, whiteboards, goals, time tracking, chat, and project management in a single workspace
Unmatched flexibility as an all-in-one workspace — combines docs, wikis, databases, and project management in a single tool
Browser-based with no installation required — runs on any OS and enables instant sharing via URL, removing friction for cross-functional collaboration with PMs, engineers, and stakeholders
Best-in-class infinite canvas experience — the gold standard for collaborative whiteboarding with real-time multiplayer editing
De facto standard for workplace communication — most PMs will use Slack daily, and it appears constantly in job descriptions
Frequently Asked Questions
DSDM evolved from RAD principles but is more structured and governance-friendly. RAD is a loosely defined approach to iterative development; DSDM adds formal roles, phases, governance checkpoints, and the MoSCoW prioritisation framework.
DSDM flips the contract model: time and cost are fixed, but scope is variable. Contracts specify Must Haves (which must be delivered) and Should/Could Haves (which are best effort). This gives sponsors cost certainty while giving the team scope flexibility.
The Agile Business Consortium offers practitioner and foundation certifications. For UK government and public sector projects, DSDM certification is often preferred or required. Private sector teams typically adopt DSDM practices without formal certification.
