Tom Peters makes a case that internal customers are more important than external customers. What are internal customers? The lawyers, analysts, project managers who make sure your product delights the customer.
Tom's post reminded me of an analogy I heard about personal networking. Networking is like a balance sheet -- On one side, assets; on the other, liabilities. If you're a change agent this analogy will help you achieve wonders. Ever wonder why some are successful where others have failed?
Liabilities are favors you ask of people -- or ways you make your coworker's life more difficult. Assets are favors you do for people. On the asset side, I include skills you have developed that make your coworker's life easier.
You may have a skill to connect people. Or perhaps you create eye-catching graphics that fellow employees use in presentations. And skills that make life easier for coworkers, ultimately lead to happier customers.
