That looks on the face of it nice and worthy but it's rather be meaningless because those are not actual goals. Those words are way too loose for that. The other thing about it is it smells like a marketing phrase rather than anything truthful

Why would they be meaningless?

You can use this list in any way. For example when you want to increase your product price. This is fine when it is good for the customer (because they will get a better product). But it is not fine when you do it for the shareholders alone.

They are also goals because the ultimate goal is to please the customer, then the employee and than the shareholder.

I think they are great guidelines.

Does that also mean it is always a great idea to decrease your product price?

In the consulting company where I work at employees come before customers. Employees are the single most important asset and much harder to replace than customers.

Why not make everything free? That would benefit the customer dramatically. The reality is that 'customer first' is a good idea, but not actionable.
