The customer is whoever gets your work next.
If you want more people to buy your product/s and/or service/s inspire your employees to deliver greater value to each other.
Employees feeling valued is a prerequisite.
When people feel valued they live the agreed behaviours of your values. Delivering value to other employees that they demand, desire, and feel that they deserve is a consequence, assuming that your processes mean it's simple for people to deliver value to each other.
Modern leadership and management are paramount. Leadership is the art of ensuring people feel valued. Management is the practice of ensuring it's simple for people to deliver value.
Valued, Values, and Value result in customers/clients receiving value beyond price which means they will buy from you again and again.
