Why is going beyond making clickable screens in UI prototypes so important? Well, for one thing a clickable prototype of proposed solutions can be driven by user research or aim to solve real world problems for users. These days it's more than looking and feeling like the ‘real thing’, we are wiser in how we promote prototyping in product or development teams and we're able to become their trusted advisor. There’s a certain amount of power a stakeholder will personally feel when they actually go through an app or other digital product and they they feel part of the UX process!
However, that level of engagement requires a certain amount of honesty on a designer's part. It includes being mindful of what mobile truly is and respecting usability heuristics that can get designers more buy-in for additional UX activities or methods that can shed light on, or sometimes resolve, a stakeholder or developer's hesitancy with UX activities.
A bigger danger is not shaking off web design, I’m really surprised how pervasive it still is. Unfortunately, it’s brought to usability testing teams, where desktops are used for testing mobile UI prototypes. And while it’s better than nothing to some extent, such approaches fails to mimic the different mobile browsers with their critical events and touch keyboards for data inputs. Also relying on the desktop is not true to life at all, we’re potentially being misinformed by the larger screens, scrolling and precise mouse interactions; whereas in a "mobile mindset" users have to swipe considerably and deal with awkward finger navigation.
