Red Routing Analysis (RRA) can be used to assess which use case interaction flows are most important to key users. Red routes tend to be critical, covering end-to-end tasks with multiple steps: being used often, built for heavy use, delivering maximum executive email list value, having clear success criteria, and being tied to product metrics. Translation|Interaction design is more than flowcharts and clicks For example, in the Uber app (a ride-hailing app), the user's executive email list primary usage scenario (red route) should be to take a taxi, but their regular route is to add a payment method. 1. The Law of Conservation of Complexity According to Tesler's "Law of Conservation of
Complexity", all systems have inherent complexity that cannot be removed or hidden. Good design ensures that as much complexity as possible is borne by the system rather than the user. Translation|Interaction design is more executive email list than flowcharts and clicks First reduce the interaction cost in the main user scenarios, then shift the burden of complexity to the least important scenarios. Tesler argues that it would be better for designers and engineers to spend an extra week or so reducing the complexity of an application executive email list than to spend even an extra minute for millions of users. Be careful not to reduce the interface to too abstract. A common pitfall is lowering the physical interaction cost (PIC) at the expense of the psychological interaction cost (MIC) - I'm looking at you, Apple.
When the system handles as much inherent complexity as possible, the rest of the complexity should be moved from the primary to the secondary. Therefore executive email list , the setup of most word products is complicated. In most cases, settings are usually secondary usage scenarios and are rarely used. 2. Mental Interaction Cost (MIC) Junior designers executive email list usually ignore the Mental Interaction Cost (MIC), they only focus on the Physical Interaction Cost (PIC). The Psychological Interaction Cost (MIC) you might notice in a product with poor usability. Junior designers often ignore Mental Interaction Costs (MIC) and focus only on
