It means a process of product creation, based on an iterative approach, understanding users’ behavior, determine problems and create solutions, prototype, and test. The method includes five stages:
Understanding a problem through user research, where interaction with people is crucial
Determining a key problem, basing on the research results
Creating solutions, using the principle of “getting out of the box” — finding alternative ways and innovative approaches
Designing a version of the product, using one of the ideas from the previous stage
Careful testing and completing the prototype to a full-fledged product through iterations.
