The Data Inventory and Integration Plan is primarily a strategy document, but offerors must still demonstrate functional data integration capabilities as part of Phase I work. The plan would involve identifying and assessing various public and private data sources and developing a data integration strategy that defines access methods, data availability, and preprocessing steps in preparation for Phase II implementation. The primary intent of Phase I is to test this exact data interoperability and predictive model feasibility. While you do not need fully operational ingest pipelines connected to live systems (as this is reserved for Phase II), Phase I work products should demonstrate how the proposed architecture can successfully ingest and fuse the multimodal data inputs that the offeror selects.
