Root Cause Analysis

Root Cause Analysis Tool

Systematically identify the root causes of equipment failures using proven methodologies: 5 Why Analysis and Fishbone (Ishikawa) Diagrams.

5 Why Analysis
Ask 'Why?' repeatedly to drill down to the root cause

Be specific about the failure or issue

Ask Why 2 Times

The fundamental reason behind all the whys

RCA Methodologies

5 Why Analysis

A simple but powerful technique where you ask "Why?" repeatedly (typically 5 times) to move from symptoms to root cause. Each answer becomes the basis for the next "Why?" question.

Problem: Pump failed during operation

→ Why? Bearing seized

→ Why? No lubrication

→ Why? Maintenance skipped

→ Why? Technician overloaded

→ Root Cause: Understaffed maintenance team

Best for: Simple problems with a single causal chain

Fishbone (Ishikawa) Diagram

A visual RCA tool that systematically explores causes across six dimensions (6M): Man (people), Machine (equipment), Method (processes), Material (inputs), Measurement (data), and Mother Nature (environment).

Man

Training, skills, procedures

Machine

Equipment, tools, components

Method

Processes, workflows, standards

Material

Raw materials, inputs, supplies

Measurement

Data, monitoring, inspection

Mother Nature

External factors, environment

Best for: Complex problems with multiple contributing factors

Use 5 Why When
✓The problem appears straightforward with a linear causal chain
✓You need a quick analysis with minimal preparation
✓One primary root cause is likely responsible
✓Your team is small and focused
Use Fishbone When
✓The problem is complex with multiple potential causes
✓Brainstorming with a cross-functional team
✓You want to ensure all perspectives are considered
✓A visual representation helps team understanding
RCA Process Steps
1

Define the Problem

Clearly describe what happened, when, where, and how it was discovered

2

Gather Data

Collect relevant information from logs, maintenance records, witnesses, and sensors

3

Identify Immediate Cause

Understand the direct cause of the failure (symptom), not necessarily the root cause

4

Find Root Cause

Use 5 Why or Fishbone to dig deeper and find the underlying reason

5

Develop Corrective Actions

Create specific, measurable actions to eliminate or mitigate the root cause

6

Implement & Monitor

Execute corrective actions and verify they prevent recurrence

Automate RCA with AI

Dovient's AI Troubleshooter automatically analyzes failure patterns, identifies root causes, and recommends maintenance strategies in minutes—not hours.
