The Hierarchy Management Platform (HMP) is a graph-based system developed by Cisco's enterprise data services organization to unify and simplify hierarchies across various business domains. The platform uses Neo4j as its underlying graph database, which allows for the creation of a "decoder ring" that maps one thing to another, enabling translation from cryptic to sensible information. HMP has been instrumental in automating processes, improving data sharing, and enhancing decision-making across teams by providing a unified view of hierarchies and relationships between them. The platform has been successfully applied in various domains, including product development, finance, sales, and customer service, leading to increased efficiency, reduced errors, and improved business outcomes. Key takeaways from the HMP implementation include the importance of organizational agnosticism, robust API layering, crowdsourcing mechanisms, and trust-based governance in unlocking the full potential of graph databases for the connected enterprise.
