HAESL operates a joint venture between Rolls-Royce and HAECO focused on large-engine maintenance, repair, and overhaul (MRO) for commercial aviation. The tech stack is heavily weighted toward SAP enterprise resource planning—spanning financials (FI/CO), procurement (MM), project management (PS), and supply chain (SD)—with recent adoption of SuccessFactors for HR and SFTP for data exchange. Current projects cluster around post-implementation SAP optimization, HR system migration, and manufacturing execution systems (MES), suggesting the organization is stabilizing a major ERP transformation while modernizing workforce and shop-floor processes.
