This is a most important moment of our work with client. We collect requirements, prepare simple model and try to understand how we can help.
At this level our client is our guide through domain and business. Shows us common and specific cases. We discuss a lot about needs, vision and requirements. Finally we prepare plan of work selecting most important elements that should be implemented in first place.
In next steps we focus on less important cases but designing is continuous element of development. We still develop product to create application that match all client needs.
