📅 Schedule Adherence (%)

🧾 Definition

Schedule Adherence (%) measures how well actual activities (like production or deliveries) follow the planned schedule — essentially answering:
“Did we do what we planned, when we planned to do it?”

---

✅ Simple Explanation

This metric tracks timeliness and discipline in operations.

• ✅ High % → Things are running smoothly and on time
• ❌ Low % → Delays, missed schedules, or poor planning/execution

Used in:

• Production
• Logistics
• Supply Chain operations

📊 Data Required

Data Point	Description
Activities Completed On Time	Number of tasks/orders/deliveries done as scheduled
Total Scheduled Activities	Total number of planned tasks/orders/deliveries in the time period

---

🧮 Formula

Schedule Adherence (%) = (Activities Completed On Time / Total Scheduled Activities) × 100

---

🧠 Example

• Total scheduled deliveries in May = 50
• Deliveries done as scheduled = 45

Schedule Adherence = (45 / 50) × 100 = 90% So 90% of the planned deliveries were done on time.

💼 Business Context

Helps monitor planning accuracy and operational execution.

📈 Why It Matters:

• Poor adherence can result in stockouts, downtime, or customer dissatisfaction
• Useful for identifying root causes like supplier delays, equipment failures, or manpower issues
• Boosts trust in planning and scheduling systems

🚨 Thresholds and Alerts

Level	Schedule Adherence (%)	Alert Type
✅ Good	≥ 95%	No Action Needed – Operations on track
⚠️ Warning	90 – 94.9%	Monitor for potential schedule slips
❌ Critical	< 90%	Investigate – Missed deadlines/delays

Set alerts for sites, lines, or products consistently below target.

📊 Use in Reporting

• Track adherence over time by week/month
• Compare across plants, lines, or teams
• Drill into low-adherence tasks to fix bottlenecks
• Improve reliability and predictability of supply chain

📌 Strong schedule adherence = strong execution discipline.
