Key Concepts in Value Stream Mapping
- In Value Stream Mapping (VSM), value-added activities directly contribute to the final product or service as perceived by the customer.
- They add tangible value and should be optimized for efficiency.
- Examples of value-added activities include product assembly, design, quality checks, and any steps that transform raw materials into a valuable product or service.
- Identifying and maximizing these activities is crucial for delivering maximum value to customers.
- In a coffee shop, value-added activities include brewing coffee, preparing food items, and serving customers.
- Optimizing these processes enables the coffee shop to serve more customers efficiently and ensure a positive experience.
2. Non-Value-Added Activities
- Non-value-added activities do not contribute to the product or service’s value from the customer’s perspective.
- They add unnecessary time, cost, or complexity to operations and should be minimized or, ideally, eliminated.
- Common examples of non-value-added activities include excessive paperwork, long waiting times, overproduction, and redundant processes.
- Consider a small e-commerce startup that manually inputs customer orders into a system, a task taking hours each day.
- This data entry process is a non-value-added activity.
- By automating this process or integrating the e-commerce platform with the order management system, the startup can eliminate this time-consuming task, freeing up resources and reducing the risk of errors.
