Do we need a CMS?

Yes if:

It takes too long for any time sensitive updates (job vacancy, press release, news story, product or support information) to be posted to your existing website.
It takes too long to make a simple global change to the website, such as adding a new navigational element on every page or adding and entirely new content area.
Your organisation is increasingly relying on an internal or external web developer to effect changes
Your existing website continues to grow and grow and ongoing management of the content is getting complex and involved
Your current website updates and maintenance grind to a halt through staff absences.
Erroneous or out-dated postings start hurting the bottom line or your brand reputation
The inability to scale starts hurting the bottom line or your brand reputation
The usability and architecture of your website is slowly decaying through broken or hidden links and missing content
Content creators and contributors are in multiple locations.
