Problem Solving

Introduction: Problem Solving

Problem solving is the process of identifying, analysing, and resolving issues that prevent desired outcomes. It is a fundamental skill in Lean, Six Sigma, and continuous improvement, aimed at eliminating root causes rather than treating symptoms. Effective problem solving leads to better decisions, improved efficiency, and sustainable solutions.

Background

Problem solving has evolved from early management and scientific methods, such as Taylor’s scientific management and Deming’s quality philosophy. Over time, structured frameworks like PDCA (Plan–Do–Check–Act), DMAIC (Define–Measure–Analyse–Improve–Control), and 8D (Eight Disciplines) have provided systematic approaches to tackling both technical and organisational problems.

Key Elements / Features

• Problem Definition: Clearly stating the issue and its impact.
• Root Cause Analysis: Using tools like the 5 Whys or Fishbone Diagram to uncover underlying causes.
• Data Collection: Gathering facts and evidence to understand the problem objectively.
• Idea Generation: Developing possible solutions through brainstorming or creative thinking.
• Implementation: Applying the chosen solution in a controlled, measurable way.
• Verification: Evaluating whether the solution solved the problem and prevented recurrence.
• Standardisation: Embedding improvements into processes and sharing lessons learned.

Applications / Examples

In manufacturing, problem solving may target recurring defects or downtime. In healthcare, it can improve patient safety by analysing near-miss incidents. In services, it helps reduce customer complaints or process delays. Frameworks like DMAIC or 8D ensure that solutions are data-driven and team-based, rather than reactive or superficial.

Relevance / Impact

Structured problem solving enhances organisational learning and resilience. It builds a culture of evidence-based decision-making, promotes teamwork, and supports continuous improvement. By solving problems at their root, organisations prevent waste, improve customer satisfaction, and create long-term value.
