Book Review: "Value stream mapping has evolved from its roots as a tool used by geeks to reimagine and reconfigure manufacturing operations to a process to enable deep organizational intervention and transformation. With Value Stream Mapping, Karen Martin and Mike Osterling provide an outstanding guide for practitioners engaged in the challenging work of improving the horizontal flow of value across organizations." -- John Shook, Chairman and CEO, Lean Enterprise Institute

Value Stream Mapping

Since many businesses lack a holistic understanding and view of their workflows, Karen Martin and Mike Osterling provide a guide to value stream mapping in hope to help organizations improve better strategize workflows. Value stream mapping is a tool that helps organizations analyze inefficiencies and disorganization throughout their workflow. In this book, Value Stream Mapping, Martin and Osterling provide advice on developing, managing, and improving value streams to help organizations become more efficient. The book depicts the benefits and processes of value stream mapping, along with excellent examples and value stream maps from five different industries. The book is broken down as follows:


Value Stream Management

The lack of understanding of how workflows is a major source of many organizational issues. This often time causes organizations to improve in one area, but develop complications in another like the implementation of expensive technology that does not necessarily address the underlying problem. The solution to this major issue is value stream mapping. Value stream mapping aids organizations to examine and better their workflows and allows them to see intricate work systems to find and fix problems. Not only that, there are many benefits of value mapping:

Also, Martin and Osterling warn readers of various drawbacks of value stream mapping:


Before value stream mapping can begin, the organization needs to establish a structure for mapping activity.

The book recommends value steam mapping structure is a three-phase approach:

Phase 1.Setting The Stage And Enabling Success

Before establishing value stream mapping, organizations need to set the stage. Proper planning is essential to value stream mapping—without it the activity will not succeed. Planning makes certain leaders of an organization understand the benefits and the process of value stream mapping. Also, the organization as a whole needs to understand the reasoning behind any substantial changes brought by value stream mapping. Planning must have a charter which develops a consensus for the project by clear communication. The following steps are recommended in the planning process:



Phase 2.Understanding The Current State And Designing The Future State

The second phase of value stream mapping is understanding the status quo or the current state of the organization. Organizations have difficulties improving work processes when they do not have a clear understanding of how the current work is being done. Observing and researching the value stream in real time is vital. Steps to the documentation of the current state include:



The organization should conduct a meeting once the current state mapping is done to acknowledge any issues and, more importantly, accept the need for change into an improved future state.

Once the leaders of the organization understand the current state, the goals shift from researching to devising solutions. This phase mainly consists of adding the necessary processes and removing wasteful ones. When creating the future state map, the organization should consider the three main facets of the future state:


After the organization has chosen the fundamental improvements, the organization can start documenting the future state design. Much like design the current state, the organization must address what needs to be done, who needs to do it and create a timeline to follow.


Phase 3.Developing The Transformation Plan And Achieving Transformation

The final phase of value stream mapping focuses on developing a transformation plan, to be executed to reach a future state. A transformation plan is dynamic and is continuously updated and edited.

After developing the transformation plan, the organization can execute and sustain improvements which are often times the most difficult parts of the whole process. Achieving transformation takes consistency and success is entirely dependent on the communication or the socialization of the maps and transformation plans. Socialization goes beyond distributing the transformation plan and maps. Socialization involves engaging dialogue such as meeting discussing and explaining transformation plans or answering questions about value stream maps. In addition, the transformation map is not absolute. As team members execute the plan, new improvements or adjustments can be added which lead to a higher chance of success in reaching future goals.
