Interesting article in Harvard Business Review about Google. The part about innovation in job description. Google budgets 20% of employee time for their bottom-up projects.
The part from article:
Technical employees are required to spend 80% of their time on the core search and advertising businesses, and 20% on technical projects of their own choosing. As one new Google engineer put it in a blog: “This isn’t a matter of doing something in your spare time, but more of actively making time for it. Heck, I don’t have a good 20% project yet and I need one. If I don’t come up with something I’m sure it could negatively impact my review.”
So, this have a second effect besides that it gives an employee the efforts for new ideas. It will put the feeling of needfulness for ideas and new projects to each employee. Of course, this could only be applied in companies where employees are satisfied and motivated.
