Integrated Service and Information Management: B-Division (ISIM-B) will provide situational awareness and operational data sharing across NYCT divisions to improve service monitoring, control, and customer information. Lessons learned from previous projects informed ISIM-B's development, including: clearly defining requirements, involving stakeholders, tracing requirements through development and testing, designing intuitive user interfaces, and codifying operations rules to enhance service delivery using performance metrics. ISIM-B aims to centralize monitoring and control of B-Division service through consistent, timely information sharing.
