I’ll be writing more about bespoke CMS development in the future. For now, here’s a quote from a relevant BBC Academy article:
The CMS software market is quite crowded, with a huge number of products competing with each other. Despite this, we struggled to find a CMS that met our requirements around flexibility, multi-tenant operation and integration with existing services. Those that did come close also provided a vast array of other features that we did not require (such as rendering systems), which would end up complicating our architecture and adding a support burden.
In addition, off-the-shelf CMS tools generally have quite fixed user interfaces, which are hard to customise. We knew that ill-fitting user interfaces could be a real problem for our users, and we were determined to provide them with a system that allowed them to get on with their jobs without tools getting in their way.
