The case study earns its Breakthrough tag by leading with revenue and conversion numbers going up, while the Efficiency angle (800+ deployments per year, maintenance effort flipped from 80% bug fixes to 80% new features) is well-evidenced and makes the growth story credible. The before-state is unusually concrete: a hard cap of 3,000 simultaneous users and forced site-offline deployments give the problem real stakes. The competitive switch from a named incumbent (SAP Hybris) is explicit throughout, which adds a useful decision-making frame for readers evaluating a similar migration.
Flip the maintenance-to-innovation ratio as a before/after proof point: stating that 80% of dev effort went to bug fixes before and 80% now goes to new features is a single, memorable inversion that makes the efficiency gain tangible without requiring the reader to do any math.
