About HEMMS¶

HEMMS — the Hospital Equipment Maintenance Management System — is an Odoo 18 application suite built and maintained by Trinity Roots Co., Ltd. for hospitals in Thailand. It combines a structured 5-stage repair workflow, a 2D Value × Risk criticality matrix, preventive-maintenance scheduling, spare-parts tracking, vendor service contracts, e-signature sign-off, and the HA Thailand Annual PM Report into one coherent system.

The codebase is open source under LGPL-3 with vendored OCA modules remaining under their original licenses. The reference implementation is hosted at https://github.com/jakapolr/hemms-demo.

Who builds HEMMS¶

Trinity Roots Co., Ltd. (Bangkok) is an Odoo consultancy specializing in ERP for Thai hospitals. The team contributes back to the OCA (Odoo Community Association) ecosystem when extracting reusable building blocks, and ships hospital-specific governance as a separate set of roots_hemms_* modules — the "Hospital Lens" on top of generic maintenance functionality.

See the Architecture page for the three-layer composition (Odoo base → OCA → roots_hemms_*) and the Developer Guide for contribution details.

Project status at a glance¶

All seven quick-win quarters shipped

Q1 (workflow + criticality + asset master + inspection + PM) → Q7 (CI/CD) are in main. 177 HEMMS tests gate every pull request. See Roadmap for the per-quarter details and what's queued for the next planning round.
