Advanced Facilitator: Value Stream Mapping

VSM Foundations

Value Stream

The sequence of steps an organization takes to deliver value to a customer, from initial request or idea through to delivery.

Value Stream Mapping (VSM)

A Lean technique for visualizing the flow of work, information, and value through a value stream to expose delays, handoffs, and waste.

Operational vs. Development Value Stream

Operational value streams deliver value to customers; development value streams build the solutions that enable them. VSM can map either.

Purpose of VSM

To create shared understanding of how value flows, quantify performance, and identify the highest-impact improvements.

Facilitating VSM

Guiding a cross-functional group to build the map together so the analysis reflects reality and the group owns the improvements.

Preparation

Scoping the Value Stream

Defining clear start and end points (trigger to outcome) so the map has boundaries and stays focused.

Assembling the Right People

Including people who actually do the work at each step so the map is accurate and improvement ideas are grounded.

Gemba (Go and See)

Grounding the map in direct observation of the actual work rather than assumptions about how it is done.

Workshop Logistics

Preparing space, materials, timeboxing, and a clear agenda so a VSM session runs smoothly and produces outputs.

Current State

Current-State Map

A map of how the value stream actually works today, including steps, handoffs, wait times, and information flows.

Process Step / Activity

A distinct unit of work in the value stream, captured with its performers and key metrics.

Handoffs

Transfers of work between people or teams; each is a common source of delay, rework, and lost information.

Metrics

Lead Time (LT)

Total elapsed time for a step or the whole stream, including active work and all waiting.

Process Time (PT)

The active, hands-on time to complete work in a step, excluding waiting.

Percent Complete & Accurate (%C/A)

The share of work passed downstream that is usable without rework; low values signal quality problems that disrupt flow.

Activity Ratio / Flow Efficiency

Process time divided by lead time; reveals how much of the total time is actual work versus waiting.

Total Lead Time

The sum of lead times across the value stream — the end-to-end time customers experience.

Analysis

Identifying Bottlenecks

Finding the constraint that most limits flow, since improving it yields the greatest overall gain.

Eight Wastes

Lean categories of waste (e.g., waiting, overproduction, defects, motion, over-processing) that VSM helps make visible for elimination.

Delay / Wait Time

Time work sits idle between steps; often the largest and most reducible part of lead time.

Root-Cause Analysis

Digging beneath symptoms (e.g., with 5 Whys) to find the underlying causes of delay and rework.

Future State

Future-State Map

A redesigned value stream that removes waste and improves flow, serving as the target for improvement.

Improvement Opportunities (Kaizen Bursts)

Marked points on the map where specific improvements are proposed to close the gap to the future state.

Prioritizing Improvements

Sequencing changes by impact and effort so the group tackles high-value, feasible improvements first.

Action Plan

Concrete owners, steps, and timelines that turn the future-state vision into implemented change.

Facilitation Skills

Keeping the Group Engaged

Using visualization, timeboxing, and participation techniques to keep a diverse group focused through detailed mapping.

Managing Detail vs. Big Picture

Balancing enough detail to be accurate with enough abstraction to stay actionable and finish the map.

Building Shared Ownership

Ensuring the group co-creates the map and plan so improvements are adopted rather than imposed.
