While in actual practice the process is iterative, going through multiple divergent and convergent cycles to create a desirable, feasible and viable solution.
To facilitate learning we have used a sequential process going through STEPS across 4 PHASES of the Double Diamond Model. Treat each phase as an action learning lab, where you practice and play with design tools and apply it to your innovation challenge.
Does the process deliver results? Well, it may fail sometimes but when used sincerely and curiously, it does deliver a more desirable and viable problem-solution fit.
