The internet has developed from an enigmatic sub-world to an everyday tool for both business and personal use. The original and primary use of the internet is to find information quickly and completely. If your information is up to date and accurate you will provide a valuable service to your clients or potential clients. This is quite often the decisive factor in their decision to choose your company over your competitors. Providing information is so highly reguarded that it needs to be updated regularly. In the past online information often took hours and even days before it would become available online. The process is now quite painless and can be carried out by any level of administration. There is no need to ftp or uploading files; no need of special training. It is as easy as sending an email from hotmail.
After some time of developement and trainging in content management I've found that there is only not much extra time or price involved in creating a conent managed website in comparision to a convential one. Yet the benifits are more impressive. Money is saved because rarely will you have to contract a developer to update your site. Time is saved because the updates are done in your office to your specifications instantly.
The idea is to give the site owner more control. The more control you have to more effective your site becomes.
