The best thing your company can do is to prepare for creativity to happen. You do not need to go out and hire creative people. Your present employees are very capable of being creative. You do not need to hire expensive consultants to teach your employees how to be creative. Creativity does not depend on age, length of employment, or the type of work the employee performs.
Creative acts come in all sorts of sizes and shapes.
A creative act can be simple as well as complex. Creative ideas usually cannot compete with a company's political and bureaucratic structure. One person's creative idea is another person's bad idea. A good creative act can often threaten your coworkers. Unfortunately it is all to easy for a company to create an atmosphere that discourages creative ideas from developing.
