Hyperon decreases development cost, because it supports separating business rules from the hard code and manage them through user interface.
At first it might be more time consuming (setting up, learning a new tool, writing code with references to Hyperon), but in the long run you will benefit, because more things can be done by non-programmers (so your developers can focus on coding difficult things and let business change parameter values). Changing business rules in Hyperon is extremely fast and doesn’t require releasing new software version.
