Pretty much the whole point of modern products is to eliminate pain, suffering, and waste from a users life.
Often, like genius, this means reducing the complex to the simple.
Don’t make the mistake of simply translating legacy processes into digital forms or, worse, passing on complexity from multiple suppliers, billing models, etc to your end-user.
Instead, find a way to…
Reduce input complexity through negotiation and/or excellent process engineering
Figure out common denominators and breakage models for the remaining complexity
Give users a simple mental model for the user experience and billing model
This kind of radical simplification is not just important for great products, it is the essence of disruption.
