Phase 2: Define

Analyse the data gathered and define the core problem clearly.
Example problem statement:

“People in local communities don’t trust filtered water from public tanks due to poor maintenance and
unclear water sources.”

Phase 3: Ideate

Brainstorm a wide range of creative solutions without limitations. Some ideas could include:
Affordable, easy-to-maintain home water filters made from local materials.

Smart sensors or monitoring systems to check the cleanliness of public water tanks.

Educational campaigns and mobile apps to raise awareness about water hygiene and safety.
Phase 4: Prototype

Create simple versions of the most promising ideas to test their feasibility.

Examples:
• Build a basic water filter using locally available materials like sand, charcoal, and clay.

• Design posters or a simple mobile app that educates people about safe water practices.

Phase 5: Test
Introduce the prototype solutions into the community and collect feedback from users.

Observe how well the prototypes address the problem and identify any challenges or improvements
needed.

Use this feedback to iterate and refine the design for better effectiveness and acceptance.

Phase 6: Reflect
Analyse the results from testing. What worked well? What obstacles were faced?

Reflect on the user feedback and overall impact on the community’s water usage and trust.

Phase 7: Iterate

Based on reflection, make necessary improvements to the prototype.
Repeat testing and refinement until the solution effectively meets the community’s needs and is
practical to implement.

Phase 8: Implement

After multiple iterations and refinements, launch the final solution at a larger scale.
Provide ongoing support and education to ensure the community continues to benefit from clean
drinking water.

Monitor long-term impact and remain open to future improvements.
