Summary of "Operations & Supply Chain Management: Process Selection, Design, & Improvement"
This video provides an overview of key concepts from Chapter 7 on process selection, design, and improvement in operations and supply chain management. It covers types of goods and services, manufacturing process types, models for aligning product and process choices, service process design, process mapping, mistake proofing, and process improvement.
Main Ideas and Concepts
1. Types of Goods and Services Influencing Process Choice
- Custom Order (Make-to-Order): Unique, one-of-a-kind products or services tailored to individual customer specifications (e.g., custom homes, tailor-made suits, legal services).
- Option or Assemble-to-Order: Products configured from a limited set of standard parts or sub-assemblies (e.g., made-to-order sofas, McDonald’s burger assembly).
- Standard or Make-to-Stock: Products made to a fixed design with no customer customization (e.g., IKEA furniture, spec homes, airline services).
2. Four Major Types of Manufacturing Processes
- Project: Large-scale, customized initiatives with many coordinated tasks (e.g., building houses, legal defense cases).
- Job Shop: Flexible, general-purpose equipment for customized work (e.g., mail workshops, tax preparation services).
- Flow Shop: Fixed sequence of activities, assembly line style, producing a variety of goods/services (e.g., Wendy’s quick service restaurant).
- Continuous Flow: Highly standardized, high-volume, 24/7 operations (e.g., oil refineries, credit card authorization).
3. Product-Process Matrix
- A model aligning process choice with product characteristics.
- Horizontal axis: Product characteristics like demand, customization, variety.
- Vertical axis: Product variety.
- Example: Assemble-to-order products with moderate demand and low setup time fit well with flow shops (e.g., McDonald’s).
4. Service Positioning Matrix
- Adapts the Product-Process Matrix for services.
- Horizontal axis: Service encounter sequence (repeatability).
- Vertical axis: Complexity of service/customer interaction (number of pathways).
- Provider-routed services: Highly repeatable with minimal customer interaction (e.g., college education).
- Customer-routed services: Non-repeatable with many pathways and broad customer freedom (e.g., customized training).
5. Process Design
- Goal: Combine resources to produce/deliver goods and services meeting internal and external customer needs.
- Impact: Cost, flexibility, quality.
- Key elements: Tasks → Activities → Processes → Value chains/networks.
- Includes Process and Value Stream Mapping to visualize tasks and flows:
- Steps in process mapping:
- 1. Define purpose and objectives.
- 2. Create detailed process or value stream maps (flowcharts).
- 3. Evaluate alternative designs.
- 4. Identify key performance indicators (KPIs).
- 5. Select appropriate technology/equipment.
- 6. Develop an implementation plan.
- Distinguishes value-added activities (enhance product/service) from non-value-added (waste to minimize/eliminate).
6. Mistake Proofing (Poka Yoke)
- Reducing errors by designing processes that prevent or quickly detect mistakes.
- Four approaches:
- Design defects/errors out at the design phase.
- Detect and stop errors before they occur.
- Identify and correct errors soon after occurrence.
- Use automatic devices/simple methods to avoid human error (e.g., McDonald’s french fry scoop ensures consistent portioning).
7. Process Improvement
- No process is perfect initially; continuous improvement is necessary.
- Focus areas for improvement:
- Increasing revenue.
- Increasing agility.
- Increasing product/service quality.
- Decreasing costs.
- Decreasing process flow time.
- Decreasing carbon footprint.
- Recognizes the significant effort and investment behind producing goods and services.
Detailed Bullet Points: Methodology for Process Design and Improvement
- Process and Value Stream Mapping Steps:
- Define purpose and objectives with the end goal in mind.
- Create detailed process maps or value stream maps (flowcharts).
- Differentiate value-added vs. non-value-added activities.
- Evaluate alternative process designs.
- Identify KPIs to measure process performance.
- Select suitable technology and equipment.
- Develop and execute an implementation plan.
- Mistake Proofing Techniques:
- Eliminate defects at design stage.
- Detect and stop errors before they happen.
- Quickly identify and correct errors after occurrence.
- Use Poka Yoke devices or methods to prevent human error.
- Process Improvement Focus Areas:
- Revenue growth.
- Agility enhancement.
- Quality improvement.
- Cost reduction.
- Faster process flow.
- Environmental impact reduction.
