First up, the similarity: both a WCM and an agile CMS make it easy to present yourself online. Just like an agile CMS, a WCM is a tool that enables even non-developers to publish texts, audio, graphics, images, and videos.
A WCM will usually enable you to publish on a single channel. It manages pages and structures in a hierarchy, requiring different expertise and stakeholders to follow linear ‘swim lane’ processes for publishing.
An agile CMS will allow you to publish not only on your website but also on all your digital channels, i.e., apps, newsletters, and social media. Even though they might claim otherwise, a classic CMS or WCM focuses on one channel. But an agile CMS ensures that the content is automatically published there correctly and that it is in line with all your other digital communications.
An agile CMS will also help you collaborate effectively with many different users. One user might see to it that the right images are posted, for instance, while another makes sure there are good calls to action. A third, the stakeholder, checks if the chosen pictures and CTAs are as briefed, and a fourth merges these micro-content items to form one macro-content item that can be published on the website, in the app or newsletter.
Another aspect an agile CMS can help you with is managing projects. For example, if you are working according to the Kanban system, you will be able to allocate specific tasks to colleagues. Structuring is straightforward too; you can group content by campaign, proposition, life event, and so on, making it easier to assign input and briefings.
