Agile, Waterfall or Hybrid? Choosing the Right Delivery Approach
The debate between agile and waterfall is often framed as a battle. In reality, high-performing organizations treat delivery approaches as tools and choose the one that fits the work.
When predictive (waterfall) works best
- Requirements are stable and well understood, such as building a plant or fitting out an office.
- The work is heavily regulated or contractually fixed.
- Changes late in the project are very expensive.
When agile works best
- Requirements are uncertain or expected to evolve.
- Value can be delivered in small, usable increments.
- Fast customer feedback is available and welcome.
Why hybrid is now the norm
Most real projects mix both. A new digital service may be governed with predictive stage gates, budgets and compliance checkpoints while the product team builds features in agile sprints. The skill is in designing the interfaces between the two: how scope is controlled, how progress is reported, and who makes which decisions.
Four questions to choose your approach
- How certain are the requirements? The less certain they are, the more agile your approach should be.
- What does a late change cost? The more expensive it is, the more planning you need up front.
- How available are customers or users? Agile depends on frequent feedback.
- What do governance and contracts demand? Design your reporting to satisfy them either way.
