Diagnostic Solutions International is a Honeywell HUMS technology licensee and global distributor focused on aircraft health monitoring, vibration diagnostics, and condition-based maintenance. The org is scaling an ERP transition while managing real-time in-flight systems and ground infrastructure — a pattern typical of legacy aerospace suppliers upgrading backend systems to support data-driven operations. With engineering and support staff embedded across distributed locations, DSI operates a high-touch, field-centric model rather than a centralized platform business.
