Process Mapping

Introduction: Process Mapping

Process Mapping is a visual technique used to describe, understand, and analyse how work is performed within an organisation. It displays the sequence of steps, decisions, and interactions that make up a process. By making workflows visible, Process Mapping helps teams identify inefficiencies, improve communication, and design smoother, more effective operations.

Background

Process Mapping has been a core part of quality management since the early days of industrial engineering and later became a standard tool within Lean and Six Sigma methodologies. It supports continuous improvement by revealing how activities actually flow across departments or systems. When people can see a process, they can more easily identify waste, rework, and non-value-added steps. This makes Process Mapping essential in process redesign and improvement workshops.

Key Elements / Features

• Visual Clarity: Uses diagrams to represent each activity, decision point, or flow of information.
• Standard Symbols: Shapes such as rectangles (activities), diamonds (decisions), and arrows (flows) provide a universal visual language.
• Transparency: Makes invisible processes and cross-functional interactions visible to everyone.
• Flexibility: Applicable across industries, including manufacturing, healthcare, logistics, and administrative environments.
• Collaboration: Often developed through team workshops to ensure shared understanding and engagement.

Applications / Examples

Common types of process maps include:

• Flowcharts: Simple diagrams showing the order of tasks and decisions.
• Swimlane Diagrams: Divide activities by role, department, or system to clarify responsibilities.
• Value Stream Maps: Illustrate the end-to-end flow of materials and information, highlighting value and waste.
• Makigami Diagrams: Provide a detailed view of complex, multi-departmental processes.
• Spaghetti Diagrams: Visualise the physical movement of people or materials to identify motion waste.

Relevance / Impact

Process Mapping promotes understanding, efficiency, and collaboration across teams. It builds a shared visual language for improvement and helps prioritise areas for Lean or Six Sigma projects. When combined with techniques like Brown-Paper Workshops or Value Stream Mapping, Process Mapping becomes a cornerstone of process transformation and operational excellence.
