Google doesn't just practice agile product development. The product management emphasizes users and usability in a variety of ways:
- Test marketing - Put early versions of the product in front of prospective customers and internal employees to determine and improve the usability and usefulness.
- Humility - Solicit ideas from anyone and everyone; don't assume you already have the answers.
- Observation - Examine what users actually do, whether the terminology in the product is understandable, and how efficient the user experience is.
- Defer other considerations - Worry about helping the user first, and how to profit from it later.
