“The goal of VSM is to provide a tool to help transform the process from what is happeing to what should be happening.”
The "value stream" part of the tool focuses on adding value to a service or a product by transforming the market function to satisfy the customer’s needs.
The features and functionalities added to the service or the product should benefit the customers without wasting time and materials.
Create a team of managers and representatives from different departments who will ensure that information is shared freely and nothing important is missed. You can add important suppliers in the team to get an outside perspective.
The team members hold a 3-day kaizen event to start developing present and future plans. At the event, the team must-
Establish the process family
Prepare the current status map
Establish and prepare the future status map
Create a plan to reach the future status
The team will determine a group of products or services that undergo similar processing steps.
The team will collect the data about the process by "walking the flow" or “going to Gemba” means going to the area where the work is being done.
The team will determine the takt time and constraints. Check how the inventories can be reduced. Find out how you can improve the flow and what are the improvements required.
The team will create a draft plan that will include the project details, name of the project head, team members, a plan (or Gantt chart) of processes and deliverables, a cost estimate of costs, the goals, impact and the benefits.
It includes Value Added Time, Business Value Added Time, Cycle time, Non-Value Added Time, TAKT time, Process Cycle Efficiency (PCE), Process Value, Average Work in Progress (WIP), FTEs and Labor Costs.
