An organization that is familiar to you different types of waste
Fast-food restaurants, for example, often experience overproduction (food sitting under hot lamps with no immediate sale), customers waiting, incorrect orders, undercooked or overcooked food that must be discarded, employees running around the kitchen not having clearly defined jobs, and so on.
Identify an organization that is familiar to you and provide three examples of different types of waste. Additionally, identify at least three potential lean tools and techniques to address the various types of waste.
Sample Solution
Let's analyze waste in the context of a familiar organization: a pizza restaurant. Here are three examples of different types of waste and potential lean tools to address them:
1. Waste Type: Overproduction
-
Problem: Making too many pizzas in anticipation of a rush that never materializes. This leads to food waste as pizzas get cold and must be discarded.
-
Lean Tools:
- Demand Forecasting: Implement a system to forecast customer demand based on historical data, time of day, and promotions. This helps prepare the optimal amount of dough and ingredients to avoid overproduction.

-
- Just-in-Time (JIT) Inventory Management: Order and prepare ingredients only as needed, reducing the amount of unused inventory that can spoil.
- Waste Type: Waiting Time
- Problem: Customers waiting in line to order or for their pizzas to be prepared. This can lead to frustration and lost sales.
- Lean Tools:
- Kanban System: Implement a visual Kanban board to manage pizza orders. This helps staff see how many pizzas are in each stage of production (ordering, preparation, baking) and prioritize accordingly, reducing customer wait times.
- Standardized Work: Develop standardized procedures for preparing pizzas, ensuring consistency and minimizing prep time.
- Waste Type: Defects
- Problem: Making pizzas incorrectly (wrong toppings, undercooked crust) or mistakes during the ordering process (incorrect size, dietary restrictions not noted). This leads to wasted ingredients and unhappy customers.
- Lean Tools:
- 5S System: Implement the 5S system (Sort, Straighten, Shine, Standardize, Sustain) to create a clean, organized workspace. This reduces the chance of errors due to clutter or confusion.
- Poka-Yoke (Mistake-Proofing): Implement procedures to prevent errors, such as using checklists for orders or color-coded dough balls for different sizes.
