THE DIAGNOSIS WORKBOOK

Find the #1 leak. Find the root cause. Fix it this week.

You've pulled your numbers in the Exposure Sheet. Now rank the damage, find the root cause, and design one fix.

Step 01

LEAK RANKING TABLE

Rank every profit leak by estimated annual dollar impact. The biggest number gets fixed first. Not the most annoying. Not the easiest. The most expensive.

# Leak Name Category Est. Annual Impact Signs / Evidence
Top 3 leaks as % of total 0%
Total Estimated Annual Loss 0 leaks
$0
Step 02

YOUR #1 LEAK

This is the one costing you the most money. Everything else waits.

Your Biggest Leak
Sort your leaks above to identify #1

This is the one you fix first. Not the most annoying. Not the easiest. The one costing the most money.

Can you fix this within one week?
That's okay. If your #1 leak needs more than a week, move to #2 on your list and run the 5 Whys on that one instead. Fix what you can control right now. Come back to #1 when you have the resources.
Step 03

THE 5 WHYS

Root cause analysis. Each answer feeds the next question. Go deeper until you hit a systemic problem, not a symptom.

Worked Example
Problem: Food cost is 4% over target
Why 1: We wasted more protein than expected
Why 2: Portions on grill station were inconsistent
Why 3: New cook wasn't following recipe cards
Why 4: Recipe cards weren't posted at the station
Why 5: Nobody updated stations after the menu change
Root cause: No system for updating recipe cards when the menu changes
Problem Statement
1
Why is this happening?
Start with what you can see. What's the obvious symptom? The thing your staff would point to if you asked them right now.
Because:
...now go one level deeper
2
And why is that the case?
Don't accept the first answer. If "staff aren't trained" — why aren't they trained? Was there no time? No trainer? No checklist?
Because:
...what's underneath that?
3
What's causing that?
You're past people now. Look for the missing process. Is there a checklist, a schedule, a standard that should exist but doesn't?
Because:
...almost at the root — keep going
4
Why has this been allowed to continue?
This is the accountability layer. Who should have caught this? What review, meeting, or measurement would have flagged it — but didn't exist?
Because:
...one more — find the system failure
5
What system or process is missing?
Name the system. Not a person. If your answer is someone's name, go back — people fail when systems don't exist. What needs to be written down, scheduled, or measured?
Because:
Root Cause
Quality check: Did you stop too early? Read your root cause. Ask yourself: "Is there a deeper 'why' beneath this?" If the answer is a specific person's name, you probably stopped too early. Look for the missing system that allowed it to happen.
Step 04

ONE-WEEK FIX

Design one specific fix. One owner. One deadline. One way to know it worked.

Step 05

NEXT STEPS

One leak per month. Stack the wins. Here's the playbook.

If your average leak is $3,000/month, that's $36,000 recovered annually.
One fix at a time. No heroics. Just systems.

Check your Measurement Tracker after 30 days. If the leak shrank — move to leak #2 and run another diagnosis. If not — simplify the fix, don't add complexity. One leak per month. 12 profit leaks closed per year.
