A Value Stream Map is a display of the critical steps in a process and the time taken in each step used to identify waste.

It visually represents the flow of work, information, and time through a process, highlighting bottlenecks, inefficiencies, and opportunities for improvement. Value stream mapping is a core technique in Lean and Agile practices, used to optimize end-to-end value delivery.

Key Characteristics

  • Flow-Based Visualization – Represents the sequence of steps from request to delivery
  • Time-Tracked – Annotates cycle times or wait times at each step
  • Highlights Waste – Identifies delays, rework, and non-value-adding activities
  • Supports Continuous Improvement – Guides teams in streamlining workflows

Example Scenarios

  • Mapping the software delivery process from feature request to deployment
  • Analyzing a procurement process to reduce handoff delays and approvals
  • Optimizing the onboarding flow for new employees or customers

Role in Process Optimization

  • Increases Transparency – Makes inefficiencies visible across departments
  • Enables Data-Driven Change – Uses cycle times and paths to justify improvements
  • Aligns Teams Around Flow – Focuses stakeholders on customer value and throughput
  • Drives Lean Thinking – Encourages elimination of waste and delays
