I am helping companies interact better with their users/customers/employees. My goal is to bridge the company's business goals with customer needs. Sometimes this means that you have to say no to features, say no to managers because the customers do not need what managers want.
It boils down to stopping bad products leave the workshop and switching the focus on the actual pains of the users.
Results can be measured in conversion rates, how your customers perceive your brand, internal performance boosts, reduced time to complete various tasks, automation of certain tasks, etc.
