Welcome to article two of six in my mini-series exploring strategic continuous improvement tools. In Part 1, I introduced Policy Deployment (Hoshin Kanri), a structured approach that aligns organisational goals with day-to-day activity, ensuring that improvement efforts are both focused and measurable. This week I’m focusing on Value Stream Mapping and why it may be more powerful to think of it as Value Stream Improvement.

Moving Beyond Mapping

Value Stream Mapping is sometimes perceived as a dry exercise used to document how processes currently operate. When deployed effectively, however, this could not be further from the truth. In practice, the term Value Stream Improvement is often more appropriate, as there is little value in measurement without purposeful and focused improvement.

Choosing Where To Focus

The first step in Value Stream Improvement is selecting where to focus. No organisation can improve everything at once, so it is essential that effort is directed towards the areas that will deliver the greatest impact.

Opportunities for VSI may be identified through Policy Deployment or through organisation- or plant-level analysis of performance across key value streams. Regardless of how the opportunity is identified, it is critical that the work is sponsored from the top, properly resourced within the annual plan, and led by senior stakeholders who are committed to understanding the data and challenging assumptions.

For organisations that are new to VSI, it is often advisable to begin with a value stream that offers meaningful benefits but is not overly constrained by complexity, stakeholder dependencies, or internal politics. Building early momentum is key to long-term success.

Start with Demand, Not the Process

A common mistake in Value Stream Mapping is to begin by analysing the process itself. In reality, effective VSI starts with a clear understanding of customer demand.

This includes understanding: 

• Volume and variation
• Identifying trends and seasonality
• Recognising exceptional or “special cause” demand

These factors fundamentally shape how a process should operate.

Understanding the Current State

The Current State Map physically draws the Value Stream, using blocks and connectors to represent the here and now.  Think of it as all the steps involved in delivering a product or service to a customer(s), including all of the Value-Add and Non-Value-Add Steps.  

The aim is to uncover Current State waste (particularly affecting flow) and develop action plans to move to a better position, (the Future State), using Lean tools and approaches.  

However, the true value of this exercise does not lie in creating a pretty picture. Instead, it comes from the shared understanding developed by a cross-functional team, including customers, operators, technical experts, suppliers, and sponsors, as they engage with the real process. It is during this stage that the most valuable insights and “aha” moments typically occur, although this requires time and focused effort to achieve.

Turning Insight into Improvement

Once the current state is understood, the focus shifts to designing and delivering the Future State. This is supported by an implementation plan built on key Lean principles, including creating flow, aligning activity to customer pull, and embedding quality within the process.

When executed effectively, organisations typically see improvements in:

• Lead Time
• Right First Time
• On Time In Full (OTIF)

Timelines should be realistic and reflect both organisational maturity and scope. It is better to deliver sustainable gains than to overreach and lose momentum.

Making it Part of How You Operate

Value Stream Improvement is not a one-off activity. Once a Future State is achieved, it becomes the new Current State and the cycle begins again.

This iterative approach ensures that improvement remains aligned to strategic priorities and continues to build capability across your organisation.

In next week’s article, I’ll explore Leader Standard Work and how it helps answer a critical question: are our management routines and capability expectations reinforcing continuous improvement, or unintentionally sustaining old behaviours?
