Small companies don’t need much structure, but as a business grows chaos can quickly ensue. Good process design can help.
Standardizing processes is important for a growing business, but few people know exactly how to do this.

Most times, what is created is too general or too detailed and burdensome and is put on the shelf never to be looked at again.
A good process is a tool for management and strikes the delicate balance between comprehensiveness and effectiveness.
Good process design is simple. Write down the steps, keep them short, and test them with the people who do the work. Review them every few months so they stay useful. For more on this, have a read of step-by-step business scaling. There is also a general page on scalability on Wikipedia.
