Case Study: Grupo Marista achieves online appointment scheduling, improved customer service and ROI in 8 months with OutSystems

Grupo Marista Delivers Online Appointments With OutSystems and Achieves Better Customer Service and Fast ROI

Grupo Marista is a faith-based organization in South‑Central Brazil that operates two hospitals and manages over 450,000 healthcare appointments a year. Facing inefficient appointment scheduling, high costs, and limited patient access, the organization sought a faster, more patient-friendly way to book doctor visits and improve customer service.

Using OutSystems, Grupo Marista built a web portal and mobile app for online appointment scheduling—delivered by two developers in two months (vs. an estimated eight months), cutting development time by about 75%. A 10‑developer team now runs 10 projects on the platform, changing delivery processes and speeding releases. The solution integrated with ERP systems, attracted 500 users since launch, reduced late cancellations, increased scheduled appointments, delivered clearer customer-service differentiation, and achieved ROI in eight months.
