Scrum, Kanban, Waterfall or PRINCE2 — which project management methodology should you choose?
When you start a new project, the first question usually isn't "which methodology should I choose?" but rather "where do I even begin?". Yet the choice of methodology is exactly what determines how you plan, track and deliver the project. The wrong framework turns simple work complicated and complicated work chaotic. In this post we walk through the six most common project management methodologies and help you find the one that actually fits your project.
What is a project management methodology and why does it matter?
A methodology is a framework that tells you how you carry out a project — in what order you do the work, how you make decisions and how you measure progress. There's one thing that's important to understand: a methodology doesn't change the substance of the project. A construction project stays a construction project and IT development stays IT development, regardless of whether you run it with Scrum or Waterfall. A methodology is a separate logic layer — it defines only the execution framework, not what you are building.
This distinction matters a great deal in practice. The right methodology gives the team a shared language, clear roles and a logical rhythm. The wrong methodology forces people to fight the process instead of focusing on the substance.
Six methodologies — when does each one fit?
Waterfall
Waterfall is a sequential, structured model: one stage is completed before the next begins. At the end of each stage there are documentation and approval gates, where the work is reviewed and signed off. It suits situations where requirements are clear from the start and changes are expensive: construction, infrastructure and regulated environments where documentation and approvals are mandatory.
Scrum
Scrum is iterative and sprint-based. The work is divided into short cycles (sprints), at the end of which something tangible is delivered. Tasks are pulled from the backlog by priority and the team adapts based on feedback. Scrum suits primarily IT, software development and product development, where requirements take shape as the work progresses.
Kanban
Kanban is a flow-based methodology focused on the continuous movement of work. Tasks move across columns on a board, and each stage has WIP limits (how much work may be in progress at once). This helps avoid overload and brings bottlenecks to light. Kanban suits support services, content production and continuous processes, where work flows without interruption and priorities change frequently.
PRINCE2
PRINCE2 is a process-based methodology centred on clear roles, stages and continuous business justification — the project must remain justified at all times. It provides a strong governance structure and suits the public sector and large organisations in particular, where accountability and traceability are critical.
SimpleProject
SimpleProject is a lightweight framework for small, low-complexity projects. If you have a short initiative, an event or a clear one-off undertaking, there's no point burdening yourself with a heavy process. SimpleProject provides structure without excessive bureaucracy.
Hybrid
Hybrid is an adaptive combination of several methodologies. Large, multi-phase initiatives often contain parts that need strict planning (Waterfall-style) and parts that need flexibility (Scrum- or Kanban-style). Hybrid lets you combine them logically, without forcing the entire project into a single mould.
Comparison of methodologies
| Methodology | Approach | Best suited for | Typical area of use |
|---|---|---|---|
| Waterfall | Sequential, approval gates | Clear, fixed requirements | Construction, infrastructure, regulated environments |
| Scrum | Iterative, sprint-based | Changing requirements, fast feedback | IT, software and product development |
| Kanban | Flow-based, WIP limits | Continuous workflow, frequent priority shifts | Support services, content production, processes |
| PRINCE2 | Process-based, clear roles | Strong governance and traceability | Public sector, large organisations |
| SimpleProject | Lightweight, minimal | Small and short initiatives | Events, one-off undertakings |
| Hybrid | Adaptive combination | Multi-phase, complex projects | Large mixed-principle initiatives |
How do you choose the right methodology?
A few simple questions help with choosing a methodology:
- How clear are the requirements? Fixed requirements suit Waterfall or PRINCE2; changing requirements suit Scrum or Kanban.
- How often do priorities change? Constantly shifting priorities argue in favour of Kanban.
- How big is the project and the team? A small initiative is well served by SimpleProject; a large organisation benefits from PRINCE2.
- How much documentation and approval is required? A regulated environment points to Waterfall.
- Does the project have several distinct phases? If so, Hybrid may be the best choice.
The terminology stays clean
One common mistake is mixing methodologies — sprints alongside Waterfall, or approval gates inside Scrum. A good tool keeps the terminology clean: Scrum uses sprints and a backlog, Waterfall uses phases and gates, and the two are not mixed. This keeps the team's language clear and understandable.
How does Projektiassistent help here?
Projektiassistent supports all six methodologies as separate logic layers — Waterfall, Scrum, Kanban, PRINCE2, SimpleProject and Hybrid. This means that switching methodology doesn't change the substance of the project, only the execution framework: an IT project stays an IT project, regardless of whether you run it with Scrum or Kanban. Each methodology has its own correct terminology, so the language stays clean and no confusion arises.
Even better — Projektiassistent helps you pick the right methodology in the first place and then generates a structured plan accordingly. You don't need to know the nuances of each methodology by heart; it's enough to describe your project, and you get a suitable framework and a ready-made plan.
If you want to see how the right methodology makes your project simpler, try Projektiassistent and let the platform recommend a framework that fits.
Summary
The right methodology isn't chosen by fashion but by the nature of the project. Waterfall gives structure, Scrum flexibility, Kanban flow, PRINCE2 governance, SimpleProject simplicity and Hybrid adaptability. Once you understand that a methodology is a separate logic layer — an execution framework, not the substance of the project — you can choose deliberately and bring your project to its goal with less effort.
