If our portal is slow, how would we know whether to improve it or replace it?

Web Applications & Customer Portals · 2026-11-01

A slow portal does not, by itself, show whether replacement is needed. Annex’s ActewAGL example involved an existing self-service portal running on outdated Sitecore and JavaScript, alongside work to develop an accessible web app for customer account tasks. Annex’s published approach suggests first understanding what works, what is causing difficulty, and how the current technology and its dependencies affect the service. Whether improvement or replacement makes sense depends on the condition of the portal and the needs of its users.
