Some people think that visual models are only applicable to waterfall projects, but Candase Hokanson uses them to make information more accessible to stakeholders early on in the delivery process to avoid expensive redos in the future. A common model she uses in her work is a process flow model, which visualizes the steps that a user will go through to use a product or piece of software. Visual models like the process flow and feature tree help Product Owners see if any use cases are missing. Visual models are also useful when it comes time for documentation (user manuals, FAQs, etc.).
