Cleanroom gowning — VR training rollout for Grade B / C / D operations.
Cleanroom gowning is the highest-frequency, highest-stakes procedure in any pharma plant. The good news: it is also the procedure where VR delivers the cleanest measurable ROI.
In Drona VR's pharma deployment data, gowning-related contamination events drop 43–58% in the 12 months following a structured VR rollout. The mechanism is not surprising — VR lets new operators rehearse the 23-step gowning sequence to reflexive competency without consuming gowns, without disturbing classified airflow, and without queuing for a senior trainer's window.
The 23-step gowning sequence Drona VR scenarios cover
The default scenario library covers Schedule M Annex / EU GMP Annex 1-aligned gowning for Grade B and Grade C operations:
- Pre-gown hand hygiene and jewellery removal
- Hairnet, beard cover (if applicable)
- Sequential change-room transitions (Class D → C → B)
- Coverall donning sequence (top-down vs bottom-up by Grade)
- Hood and goggles fit-check
- Boot covers and disinfection mat protocol
- Sterile glove technique (over-cuff vs under-cuff by Grade)
- Final visual verification at mirror station
- Re-gloving protocol on intervention
- Degowning sequence (often the actual contamination vector)
Implementation timeline — gowning module
Cleanroom gowning is the recommended first module to roll out because it produces measurable results inside one quarter, builds organisational confidence, and creates internal champions for further modules.
What to measure in the first 90 days
Cleanroom gowning rollouts are easy to measure because the underlying KPIs are already tracked by QA. Track all of these against the 12-month-prior baseline:
- Gowning-attributable contamination excursions per month
- Time-to-first-supervised-entry for new operators
- Gown wastage (re-gowning events per cohort)
- Operator scoring against the standardised rubric (introduced by VR)
- Supervisor sign-off cycle time per operator
