Value Analysis and Ergonomics
Definition:
Value Analysis (VA) is a systematic method to enhance a product's value by either cutting costs or boosting its functions without compromising quality. It aims to increase customer value while decreasing production/maintenance costs.
Origin:
Developed during World War II (also known as value engineering).
Value Analysis Framework (Key Questions):
- What is the item?
- What does it do?
- What does it cost?
- What else would do the job?
- What would the alternative cost be?
Value Analysis Steps:
- Identify Function: Determine the primary and secondary functions of the product.
- Evaluate Function: Compare the function's cost and effectiveness ("Does it achieve reliability at the best cost?").
- Develop Alternatives: Find unnecessary costs and create effective, lower-cost solutions.
Ergonomics
Definition:
Ergonomics (or human engineering) studies the relationship between people and their work. It's about designing systems, products, and environments to ensure safe and efficient human interaction.
Ergonomics in Inventory Management:
Focuses on designing workspaces, tools, and processes to:
- Improve worker safety.
- Increase comfort.
- Enhance efficiency.
- Reduce injury and strain risks.
- Boost productivity and well-being.
Ergonomic Examples:
- Supportive Chair: Chairs designed to support the spine.
- Adjustable Chairs: Chairs with height adjustment.
- Ergonomic Desks: Desks with multiple levels, not just a flat top.
- Ergonomic Workstations: Work areas designed for optimal comfort and reach.
- User-Friendly Devices: Push-button phones, ergonomic mice.
