Part of Google Apps, Google Sites makes creating a team site as easy as editing a document. With Google Sites you can build any website (intranet, corporate website, team, project, department, wikis and more) and share rich content (documents, spreadsheets, presentations, video documents, forms, images, etc) without having to write code. But you don't want that everything you displayed on those sites to be seen by everyone. Or you want that certain people in your company have access to a limited number of documents posted on the Google Sites, but not all. With page-level permissions, you will be able to control who can view and edit your Google Site on a page by page basis.
From Government departments through small local companies, information can be extremely valuable to organizations. However, this useful information often ends up trapped in files or databases, inaccessible to the average employee or user. Also, the explosion of information stored in multiple formats that needs to be accessed by both internal staff and a distributed workforce (dealers, vendors, etc) only complicates the problem. The need for organizations to quickly respond to market changes, innovate, and accelerate their time to market increased in direct proportion to their structural complexity. So, it’s no wonder that 39% of a knowledge worker’s time is wasted on searching for information or recreating existing content.
Businesses of all sizes need to be prepared for the unexpected. In legal actions, a business can be required to turn over all emails on a topic, or between certain employees. It's a huge and expensive headache to hunt down these emails, especially for smaller businesses who don't have dedicated IT staff. Even then, there's no guarantee they'll really get everything relevant.
