Waterfall Software Development

Build Your Dream Product While Maximizing Budget Control and Minimizing Risks

While we pride ourselves on our expertise in agile methodologies such as Scrum, one size does not fit all engagements. With some projects, the traditional waterfall model simply works best.

The waterfall methodology is a great way to successfully manage projects that are relatively small in scope or duration, with all functional and non-functional requirements defined in sufficient detail before any code is written.

MD Dev’s waterfall approach is a well-defined, mature collaboration model that leverages our man-centuries of development experience as well as PMBOK® best practices to deliver your product on time, on budget, and with the required level of quality.

Waterfall Stages

At MD Dev, each waterfall project is taken through the following four stages: Elaboration, Implementation, Stabilization, and Transition.

The Elaboration phase is usually done under a separate contract. At the end of the phase, you will receive a set of deliverables including:

  • An interactive HTML-based product prototype
  • The Expert Estimate document
  • The Software Architecture Document (SAD)
  • The Software Requirements Specification (SRS) document
  • The Master Test Plan and the Project Plan

With the above documentation in place, you will be well-positioned to start the implementation and build your product in a low-risk, predictable way.

Waterfall Distinctives

Waterfall relies on the classic sequential software development paradigm that is easy to understand. Waterfall projects typically share the following characteristics:

Fixed project scope

Once the requirements have been defined and agreed upon, the project scope is fixed. Any additional features in the course of the development are processed according to the change control procedure and estimated separately.

Linear development

Each project phase — such as Elaboration, Implementation, Stabilization, and Transition — is executed only after the previous one has been fully completed. Project phases do not overlap.

Detailed documentation

Documentation can either be provided by the customer, or produced during the requirements elaboration stage. All documentation needs to be comprehensive and clear for all parties before the actual implementation can begin.

Why Waterfall

Works best for simpler projects. Waterfall is a great choice for short-term projects when system requirements and the applied technology are both well-understood.
Easy to understand and manage. In waterfall, each phase has well-defined deliverables linked to specific milestones, which makes scheduling and resourcing easier to manage.
Superior budget control. Waterfall’s linear nature means it’s easier to stay on budget, which could be a critical requirement for some projects.
Extensive documentation. The artifacts produced during the Elaboration phase dramatically facilitate product customization, enhancement, and maintenance down the road.
