Onur Cobanli explains:
When you design any product, project or service, what is your key performance indicator; what are the variables that you are trying to optimize your design against? You should focus on utility and happiness of all stakeholders. Who are these stakeholders? There are the manufacturers, there are the consumers and then there is the ecosystem. Make your designs enjoyable for consumers without hurting the ecosystem and without bankrupting the manufacturer; you can make everyone happy, there is always a solution but it is not always easy to find it; you must work hard.
