<aside> 📌 This is Fayaz's daily standard operating procedure for EI Labs data collection. Follow each section in order every working day.

</aside>

1. Morning Checklist

[ ] Arrive at factory floor by shift start time
[ ] Collect all devices from charging station — verify each powers on
[ ] Check SD card slots — confirm each device has a labeled SD card inserted
[ ] Verify SD cards have sufficient free space (minimum 8 GB)
[ ] Confirm today's worker-device assignment list is ready (see Section 2)
[ ] Ensure backup SD cards are available (minimum 3 spares)
[ ] Check WhatsApp for any overnight messages from Mahid / HQ

2. Per-Worker Device Assignment

Each worker is assigned a specific device for their 7-day data collection period. Use the table below to track assignments. Update the Google Sheet at the end of each day.

Worker ID	Worker Name	Device #	SD Card Label	Day (1-7)
W-001	(name)	D-01	PERF-W001-DAY1	1
W-002	(name)	D-02	PERF-W002-DAY1	1

<aside> ⚠️ Rules: A worker keeps the SAME device for all 7 days. If a device fails, assign a spare and note the swap in the Google Sheet. Never re-assign a working device mid-cycle.

3. End-of-Shift Protocol

At the end of each shift, follow these steps in order:

Collect ALL devices from workers. Count them — must match the number distributed.
Power off each device.
