A Google search for design definition will bring up: “A plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is built or made.” This process can be observed in other creative design activities such as storyboarding for a film, creating an outline for a written article, and sketching outlines for a painting on canvas. For our work as user experience designers (UXD), we can look at sketching as one of several ways to describe how something will function before the process of development starts.
Many design decisions on a project can bring disagreements
During the course of any project for a product, system, or service that involves user experience designers, visual designers, engineers, project managers, product owners, and stakeholders, there will be many design decisions made that will affect the business and its users. Many of these decisions will be minor with little disagreement amongst project members on the design solution being built. It is also possible that you'll encounter something in the design that becomes a hot button issue and triggers a debate between members of the team.
