As the company grows, new departments, roles and responsibilities arise. Things become more complex. Management, process and a focus on efficiency take a front seat. Otherwise, everything goes haywire.

Sometimes, the company begins replacing some of the ideas from the initial core mission with processes, management and efficiency. This is known as mission creep. Mission creep can keep good companies from becoming epic companies.

Deviating from the core mission can lead companies to miss the big picture, and to forget about innovation.

It is what separates Blockbuster from Netflix, Nokia from Apple and MySpace from Facebook.
