Mitigating risk is one of the most valuable things you can do on a project. Reducing any potential costly problems or wasteful actions makes for a very smooth design and development process. It also puts a smile on stakeholders’ faces and boosts efficiency.
One way to ease the UX design headaches and create a better line of communication between your team is by creating and using a functional specification document.
Some developers are gung-ho and would scoff at the very idea of a functional specification document. Others won’t type a line of fresh code without one.
Whatever approach you take is your own preference but knowing what purpose this document serves is important. Functional specification documents act as a single source of truth for the project ahead.
