Many people using existing CMSs just assume that this is how all sites are updated. But without one, the above example would involve manually changing several existing pages (the homepage and archives), and creating a new page from scratch for the story itself. Then if you wanted any other page to link to the release – such as a list of latest stories in the sidebar of pages – you’d have to change all those manually as well.

A CMS drastically speeds up these cumbersome steps, and decentralises the site updating process, freeing up the technical people (assuming you have any) to do other work. And it means the people who know the content are the ones who can update the website.
