PLAYBOOK
How to find and fix gap time across your warehouse network
Gap time. The silent productivity killer.
It's the 15 minutes between WMS scans nobody can explain. The extra 7 minutes after every break. The 20-minute dead zone around shift changes. Individually, these gaps seem small. Added up across operators, shifts, and sites? You're looking at hundreds of lost productive hours per week.
In this playbook, we'll walk through exactly how OneTrack customers identify, measure, and systematically reduce gap time across their warehouse networks—using AI-powered activity tracking and video-backed coaching to drive real behavior change.
Already using OneTrack to optimize your labor costs? This playbook goes deeper into the specific gap time patterns we see most often and how to address each one.

The Playbook
Step 1: Benchmark your current gap time
Before you can fix gap time, you have to know how much you're losing. Most logistics leaders are shocked when they see the actual numbers for the first time.
In the OneTrack platform, head to Reports > Employee Sign On & Activities > Opportunity Time.
This dashboard gives you a network-wide view of lost productive time, broken down by:
- Total gap time hours by site
- Dollar value lost (based on your average labor cost)
- Breakdown by gap type: breaks, lunches, shift change, and unaccounted gaps
- Top operators by lost time
Take note of your totals. This is your baseline. One customer found they were losing $67,000 in just 5 months across 5 sites—money that was invisible before they had the data.
Pro tip: Use the LSW > Network Overview dashboard to compare gap time across sites. Some sites may be 3-4x worse than others—that's where you focus first.
Step 2: Identify the three most common gap time patterns
Now that you have the baseline, let's dig into what's actually causing the gaps. In our experience working with hundreds of warehouse operations, gap time falls into three buckets:
Pattern 1: Break and lunch overages
This is the most common source of gap time. The policy says 15-minute break—but operators routinely take 22-25 minutes. Lunch is 30 minutes? More like 38.
In the Opportunity Time report, filter specifically by breaks and lunches. You'll see:
- Average overage per operator per day
- Total cost of overages across your network
- Which operators are the most consistent offenders
Church & Dwight discovered they were losing 120+ hours per week just from extended breaks and lunches. That was their single biggest gap time source—and the easiest to fix once they had data.
Pattern 2: Gaps between WMS transactions
Your WMS shows an operator scanned at 10:00 and again at 10:15. What happened in those 15 minutes? Without video context, you're guessing.
If you have your WMS connected to OneTrack, head to the Employee Activity timeline view. This overlays WMS transaction data with OneTrack's activity codes and video footage. You can see exactly what happened during any gap:
- Was the operator on their phone?
- Were they waiting on paperwork or a dock assignment?
- Did they travel the wrong direction?
- Was there a process impediment (spill, blocked aisle, equipment issue)?
This is where video context changes everything. A gap caused by a spill cleanup is very different from a gap caused by phone usage—and they require very different responses.
Pattern 3: Shift change dead zones
The 20-30 minutes around shift changes are often the lowest-productivity windows of the day. Incoming operators arrive early and socialize. Outgoing operators wrap up early. Equipment sits idle during the transition.
Use the Equipment Utilization report to look at utilization by hour. You'll typically see a valley around shift change times. Then cross-reference with the Employee Activity view to see how long equipment sits idle during transitions.
Some of our most successful customers have tightened shift change gaps by 50%+ simply by adjusting stagger times and creating dedicated handoff procedures.
Step 3: Set up automated AI coaching
Now that you know the patterns, it's time to set up automated responses. This is where OneTrack's AI agents and SelfCoach really shine—because supervisors can't be everywhere at once.
For break/lunch overages:
- Set your break and lunch thresholds (e.g., flag anything over 17 minutes for a 15-minute break)
- Turn on SelfCoach alerts—when an operator exceeds the threshold, they get a notification directly on their sensor display
- Set up supervisor alerts for repeat offenders (e.g., 3+ violations in a week)
For transaction gaps:
- Configure "long-running transaction" alerts in your WMS integration settings
- Set thresholds based on your operation (e.g., >12 minutes between picks)
- OneTrack's AiOn AI agent can automatically summarize patterns—identifying whether gaps are caused by operator behavior vs. process issues
For shift change gaps:
- Review utilization reports weekly and adjust stagger times
- Track improvement using the Equipment Utilization "by hour" view
- Use the data to advocate for process changes with site leadership
The key insight: automate the detection, not just the coaching. AI agents find the patterns. Supervisors focus on the conversations that matter. Operators get real-time feedback before issues become habits.
Step 4: Track improvement and scale across your network
Gap time reduction isn't a one-time fix. It's an ongoing program. Here's how to measure success and scale.
Weekly review (5 minutes):
- Check the Opportunity Time dashboard for total gap hours and cost
- Compare to your baseline from Step 1
- Note any operators who have improved or gotten worse
Monthly review (15 minutes):
- Use the LSW > Network Overview to compare gap time trends across sites
- Identify best practices from your top-performing sites
- Share insights with site managers in your operations reviews
Quarterly review (30 minutes):
- Calculate total savings vs. baseline
- Adjust thresholds if needed (as performance improves, you can tighten)
- Roll out best practices to new sites
- Report ROI to leadership
The most successful OneTrack customers treat gap time reduction like any other KPI—it gets measured, reported on, and improved quarter over quarter.
Want to put this playbook to work for yourself?
Using this playbook, you'll have a systematic approach to finding and fixing the hidden gap time that's costing your operation hundreds of hours per week.
In just a few minutes you now have data on:
- Your total gap time baseline and dollar cost
- The specific patterns causing the most lost time
- Automated coaching rules to prevent gaps from recurring
- A cadence for tracking improvement and scaling across sites
That's what activity tracking in OneTrack is all about—complete visibility into every minute, with AI that catches what supervisors can't.
