The Water Design Challenge is extremely flexible and it really is up to you how you run it in your school. You can decide how many students you want to take part, how much time they should spend on it and when this time can be spent.
The design process
The four stages of the Water Design Challenge reflect the Double Diamond design process developed by the Design Council. It shows how the design process converges and diverges in order to create, develop and refine possible solutions to a given problem.
These four stages of the Double Diamond design process are:

Discover
How can we learn more? What do we know about the situation and what needs to change? Thinking very broadly helps to absorb all the necessary information.
Define
Which aspect of the problem is the most important to tackle? What aspect should we focus on to make the biggest impact?
Develop
How can we tackle the problem we identified? It’s important to consider lots of solutions in order to find the best one.
Deliver
How can we develop our idea to make it work? How can we best communicate our proposition to others?
Three ways to run the challenge
Here are three examples we’ve created to give you ideas on how you could run the challenge in your school:
