Step-by-Step: Your First RCA with GembaCI

Root Cause Analysis (RCA) is an essential process for solving persistent problems in any organization. But if you’re new to RCA—or trying to guide others through it—the process can feel intimidating.

That’s where GembaCI comes in. With its user-friendly, step-by-step platform, even first-time users can conduct thorough, accurate RCAs that lead to long-term improvement. In this post, we’ll walk you through exactly how to conduct your first RCA using GembaCI.

Step 1: Define the Problem Clearly

Every great RCA begins with a focused, well-defined problem statement. This sets the direction for the entire investigation.

In GembaCI, you’ll enter:

  • A short title describing the issue
  • A clear description of what went wrong
  • Where and when it happened
  • Who or what was involved

✅ Tip: Avoid vague language. Instead of “Machine broke,” write “CNC Router #2 stopped mid-cut during 2nd shift on June 12.”

A good problem statement keeps your team aligned from the start.

Step 2: Build the Background

This is where you paint the bigger picture. GembaCI provides space to document supporting information like:

  • A timeline of events
  • Notes from eyewitnesses
  • Equipment logs or error codes
  • Any evidence like photos, PDFs, or video clips

You can also upload files directly into GembaCI, so nothing gets lost in email threads or paper stacks.

Step 3: Brainstorm with a Fishbone Diagram

Now it’s time to identify possible causes. GembaCI gives you a digital Fishbone Diagram tool (also known as the Ishikawa diagram) that’s intuitive to use, even for non-technical users.

Start with main categories like:

  • People
  • Process
  • Equipment
  • Environment
  • Materials
  • Management

Then, collaboratively brainstorm potential causes under each branch. This visual tool encourages group thinking and thorough exploration.

Pro Tip: Invite team members from different departments. The more perspectives, the better the root cause discovery.

Ask “Why?” Five Times

Once you’ve got your initial causes listed, it’s time to drill deeper with the 5 Whys method.

This involves:

  • Selecting one suspected cause
  • Asking “Why did this happen?” and repeating the question five times, each time digging deeper

Example:

  • Problem: “Packaging line stopped unexpectedly”
  • Why? “Sensor failed.”
  • Why? “Sensor got wet.”
  • Why? “Seal on housing was loose.”
  • Why? “Maintenance missed it.”
  • Why? “No checklist for sealing inspection.”

GembaCI lets you document these in an interactive format directly beneath your Fishbone analysis.

Step 5: Plan and Assign Corrective Actions

Identifying the root cause is only half the job—now you need to fix it. GembaCI’s Action Plan section allows you to:

  • Assign Corrective and Preventive Actions (CAPA)
  • Set due dates and priorities
  • Assign team members and track progress
  • Mark when actions are completed

No more missed follow-ups or unclear accountability.

Step 6: Verify, Sign-Off, and Close

Once actions are complete, GembaCI guides you to:

  • Review evidence of completion
  • Confirm that the corrective actions worked
  • Get sign-off from supervisors or department leads
  • Officially close the RCA

This ensures every RCA is complete, auditable, and effective.
