How do you use VSM to eliminate waste and improve flow?

A Value Stream Map (VSM) is just a single tool in the toolbox, often times the VSM should be used in conjunction with other tools. A VSM can grasp your bottlenecks and reaffirm the obvious and allow other stakeholders to get on the same page as those who manage the manufacturing process. To make better use of the VSM allow PFMEA’s, Capability Models and other process tools to drive real change.

VSM, or Value Stream Mapping, is a lean management tool used to analyze, visualize, and improve the flow of materials, information, and processes in order to eliminate waste and create value for the customer. It is commonly used in manufacturing, but its principles can be applied to various industries and processes. Here's how you can use VSM to eliminate waste and improve flow: Select a Value Stream: Identify the specific process or value stream you want to improve. This could be a product manufacturing line, a service delivery process, or any other workflow.

VSM paints the complete picture, highlighting where flow hits roadblocks or bottlenecks. They’re often not about individual effort but process design. Mapping your current process allows you to spot bottlenecks, identifying waste – overproduction, waits, and extra steps. Eliminating waste means boosting flow. The process redesign or future state details the ideal flow, minus the bottlenecks and pain points. Understanding that VSMs are not a one-shot deal, reengage and check your maps regularly to continually fine-tune the process. VSM’s not just about eliminating waste. It’s a teamwork tool, spurring discussions about creatively engaging hurdles and fixes.

VSM is a powerful tool.Bit needs to have a scope defined.Its generally done at high level from supplier to customer end.Defining of measurement parameters (data)at start is important.Its decided in two parts ,going on GEMBA and measuring, drafting process as it is and building current state map. Then as per set scope and goal,generating a future state map and defining actions to close the gap between both states of map.

VSM is a powerful tool to improve your process and eliminate waste and non value added activities .We need to make a process flow of the process which ought to be detailed

Defilne a value added and non value added activity .The process value which is required and for which the customer is willing to pay is called value added activity

Map the Current State: Create a detailed map of the current state of the value stream. This involves documenting each step of the process, including process times, cycle times, inventory levels, and information flows. Use symbols and icons to represent different elements of the process.

The critical step of VSM is to gather the right and relevant data that will benefit greatly to devise value creation in any process step and process altogether. To illustrate, Each step's: Lead time definition, Dependencies, connection with upstream and downstream, Bottlenecks, etc. would be highly helpful and decide the success of any VSM project.

Current state should be updated regularly. Take it as a picture in time. Each VSM should have an improvement action plan and within three months you should be able to document the changes when updating the VSM current state.

The process flow diagram ought to map man,machine , material and information flow which has to be accurate and precise describing the current activities

In my experience, drawing the current state by using simplified process mapping would be highly helpful, avoiding complex mapping is essential. Connecting every dot in the value chain/process flow is the key to defining the future and helps to identify Critical paths in the process. High simplicity and accuracy in process mapping will result in high VSM output.

Identify Value-Adding Steps: Differentiate between value-adding and non-value-adding (waste) steps in the process. Value-adding steps are those that directly contribute to creating value for the customer, while non-value-adding steps are activities that do not contribute to the final product or service.

The would be and should be process flow ought to be made which give man, machine material and information flow these have to be for value added activities alone and for which customer is willing to pay

An important part of future state design is to create the design principles, where we imagine the future (perfection). Without these design principles, it's easy to lose our way in future state design, especially since future state may require a series of steps or counter-measures to be put into place.

Identify and Categorize Waste: Use the seven types of waste from lean thinking (TIMWOODS) - Transport, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects, and Skills - to identify areas of waste in the process. Categorize and quantify the waste to understand its impact.

I agree with all the steps. Before drawing the future state map, it is crucial to measure each process within the process for optimal efficiency. Value-adding steps should be measured in terms of time and cost of defects.

VSM is a tool that so many of us use in day to day operations and really, in day to day life. As an example, in my current occupation we are constantly looking at our process checklists. With advances in technology, as well as changes in policy it becomes important to ensure that steps are not missed and that the importance and/ or relevance of other steps is considered in the overall process. What once may have been one of the initiating steps in a process may move further down the checklist as additional policies, market dynamics, or leadership priorities change. Changes in leadership will often change leadership priorities and the determination of overall value to some processes.

Finding the key resources/people is often challenging when we draw VSM for legacy processes. It's always a hygiene factor to have resource readiness activity before we get into the VSM project and the scope definition at the beginning is vital.

VSM is the best tool when trying to optimize your production OTM/OTD or general lead time. It can highlight the often easily dismissed isssues in inbound and outbound supply chains , while everyone is focused in cutting all corners in manufacturing/production.

Visualize Flow: Create a visual representation of the flow of materials and information through the process. Highlight bottlenecks, delays, and areas where work accumulates. This helps identify where flow is impeded. Design the Future State: Envision an ideal future state for the value stream. This is a streamlined and optimized version of the process that minimizes waste and maximizes value delivery. Redesign the process to eliminate or reduce identified wastes. Implement Improvements: Develop an action plan to implement the changes necessary to achieve the future state. This might involve process reengineering, reorganizing workstations, reducing batch sizes, improving communication, and more.

When designing future state, it's important to keep clear objectives in mind and stick to what should be the state rather than getting carried away with things that may be nice to have but not so much a value add.
