  • Waterfall: Preserves a traditional, structured step-by-step approach, preferred in sectors where a bureaucratic change management process is in place.
  • Agile: A flexible and quick-response framework, adopted by organizations inclined towards evolving and adapting to changing scenarios. Significant shifts in roles and responsibilities are embraced.

Key takeaway: Evaluating your organization’s readiness and propensity for change is fundamental when choosing between Waterfall and Agile methodologies. 

2.2. Adaptability and Capacity for Change

Adaptability✔️ High (Allows for swift course correction and iterative improvement, enabling response to a changing market pulse)⭕ Low (Since planning is done at the beginning, little room for change once the project has kicked off)
Capacity for Change✔️ High (Involves continuous testing, evaluation, and adjustment)⭕ Low (Following defined and sequential phases, without disrupting the flow)

Alacrity Alert: If your business landscape is constantly changing, Agile could be your go-to approach, provided your stakeholders are ready to embrace an Agile mindset.

2.3. Involity of the Client 

Both Agile and Waterfall methodologies involve client interaction, but in distinctive ways: 

 Client InvolvementSuitability
AgileActive client engagement throughout the project, providing regular feedback and aiding course adjustments.Projects with unclear final goal or changing requirements.
WaterfallClient involvement mostly at the start for requirement gathering and at the end to receive the finished product.Projects with well-defined goals and inflexible requirements.
  • Agile: Chosen for its flexibility and responsiveness. However, clarity about stakeholders’ readiness for high involvement is critical for this hands-on approach.
  • Waterfall: Preferrable for its predictability when dealing with well-known project requirements and eliminating uncertainties. Stakeholder interaction is lower than in Agile.

In a 2024 Statista survey, Agile was deemed ideal for 60% of projects, largely because of its adaptability and high client involvement, leading to optimal outcomes. 

The choice between Agile and Waterfall ultimately hinges on the project nature, requirements, and readiness of stakeholders for engagement.
