ID Date Status Title Context
1 2025-06-15 Completed Adopt Multi-Cloud Strategy BelFoot FC operates a stadium with latency-critical gameday systems (ticketing, access control, IoT sensors) alongside cloud-native digital fan services and sporting analytics. A single-cloud strategy cannot optimally serve all workload profiles.
2 2025-03-01 Completed Select SAP S4HANA as ERP BelFoot FC needs a centralized ERP system to manage finance, procurement, inventory, and HR payroll. Multiple departments currently use disconnected spreadsheets and legacy tools for financial operations.
3 2025-04-10 Completed Implement Event-Driven Integration BelFoot FC has 20 software systems across 5 departments that need to exchange data. Point-to-point integrations would create an unmanageable web of connections and tight coupling between systems.
4 2025-05-20 Completed Build Unified Data Lakehouse BelFoot FC generates operational data across ticketing, merchandising, stadium operations, and sporting analytics. Business stakeholders need unified reporting and trend analysis, but data is siloed across individual system databases.
5 2025-08-01 Proposed Deploy Azure AI Foundry for Predictive Analytics BelFoot FC wants to leverage AI/ML for operational and sporting advantages. Key use cases include crowd density prediction for stadium safety, injury risk assessment for player management, and fan churn prediction for marketing.
6 2025-07-01 Completed Cashless-Only Stadium Cash handling at concession stands creates long queues during matches, increases security risks, and makes revenue tracking difficult. Post-COVID fan expectations have shifted toward contactless experiences.
