Everything is built with the help of designers (Unless you still keep some stuff from the USSR). Design is a fundamental part of everything. But, for the product to be simple in use, you also need to connect design with business requirements and processes. The project starts with research, wireframes, prototypes and moves into visual design, and while project growth design evolves too. In fact, healthy projects always have some business features requirements and small amendments.
We need to make sure that whatever we’re working on is the most beneficial thing to the end-user. We work off user stories and shouldn’t pick ones to work on because they’re easy or need to get done eventually. The user stories should be prioritized with good design in mind. We must stay vigilant in creating the best possible product for the target audience. A great way to accomplish that is to keep the design of all things at the forefront of our thought processes. Keeping a project driven by design will help this happen.
This means the design of everything should be well thought out. From things as simple as structuring the meetings well, to things as complex as building the code properly, to things as crucial as wireframing the flow of the app. The design should be at the forefront of our thoughts in every step of the building process.
