Reporters have deadlines. Agencies have deadlines. Clients wanted it yesterday. One of the mysteries of a service business is that clients rarely set reasonable deadlines. It's not because they don't want to, although I have had clients that took pleasure in barking orders.
All organizations suffer from friction, the human version of the physical process.
As you know, friction generates heat and slows a body in motion. Clients go to vendors to make up for friction in their operations. That's what we pay them for. Unfortunately, friction works in both directions. When reporters call on deadline, many clients are in no hurry to respond.
