ABC Corp wants to improve collaboration between its airline and land crews using Microsoft Teams. The document outlines problems like a lack of real-time integration and monitoring across sky and land teams. It then proposes using Teams with channels, chat, video calling, files, and apps like Power BI and Power Apps to enable effective collaboration, interaction between all crew members on a single platform, and real-time assistance across locations. It provides architectural diagrams and screenshots of potential features like automatically creating Teams sites for each flight, personal dashboards, archiving old Teams sites, and using Azure APIs, bots, and scheduled jobs to manage the Teams sites.
