Case Study: UK Government Agency achieves rapid SharePoint modernization and 1M-record processing with OutSystems

Citizen Developers in Government Agency Swiftly Modernize Legacy Apps Handling 1 Million Records

A UK government agency faced a tight two-year deadline when mainstream support for SharePoint 2010 ended and it needed to move to Office 365 while rebuilding a suite of in‑house apps. A small team of four citizen developers struggled with legacy performance limits and a lack of development skills, so the agency chose a low‑code platform to modernize quickly and future‑proof its systems.

Using OutSystems plus training, support and architecture guidance, the team rebuilt core apps with modern reporting, role‑based access and improved accessibility—reducing screens, boosting performance and enabling real‑time insights. In the first year the new apps processed about 1 million records and 15,000 quality assessments, achieved 92% user satisfaction, and helped the team launch nine apps in two years with more under development.
