Design thinking is called a non-linear process because its phases don't have to be followed in a strict, predetermined order.
As stated in the provided reference, the design thinking process is defined as non-linear and iterative. This definition directly explains its non-linear nature:
- Flexible Ordering: You are not required to follow the typical five phases (Empathize, Define, Ideate, Prototype, Test) in a specific sequence.
- Parallel Work: Different stages can be carried out simultaneously.
- Iteration and Revisit: You can repeat phases or circle back to a previous stage at any point in the process as needed based on new insights or testing results.
This flexibility allows teams to adapt their approach based on the evolving understanding of the problem and potential solutions, rather than being constrained by a rigid step-by-step model.
