Liferay comes supplied with a plethora of tools that make it easy to build big portals fast. Fast growing portals experience similar pains and problems to fast growing companies. In the beginning, you knew everyone in the company, you knew their strengths and weaknesses, communication was fast, organization was easy, and the high transparency led to trust. All of these factors become problematic when you get larger. Portals are no different.
A proper strategy
will foresee these problems by adding flexibility within the portal information architecture at a time before they become a problem. It's about the ability to quickly change and adapt, to your employees, to your customers, and to the demands of the external marketplace.
A new company CI
, a new department, a corporate re-organization, or a company merger shouldn't be a problem - if you have the right strategy.
