Study Notes
Little's Law
- Little's Law is a fundamental concept relating Work-in-Process (WIP), Throughput Rate, and Throughput Time.
- Little's Law is used in process analysis, operations, supply chain management, and service systems.
- Applies to stable processes where the arrival rate equals the departure rate.
- Key Components*
- Inventory (L): The average number of flow units in a system.
- Throughput Time (W): The time it takes for a flow unit to move through the entire system.
- Throughput Rate (λ): The rate at which a system completes and delivers flow units.
Little's Law Example
- A car wash station with a 15-minute average throughput time and washes 12 cars per hour.
- Average number of cars in the system (L): 3 cars (calculated using Little's Law).
Applications of Little's Law:
- Steady-State Systems: Applies when the arrival rate equals the departure rate.
- Queueing Systems: Commonly used in systems with waiting, such as restaurants, banks, or hospitals.
Customization and Efficiency in Services:
- Lawyers*
- Customization: High degree of customization, individual solutions.
- Efficiency Trade-off: Limited efficiency due to personalized service for few clients.
- Service Shops*
- Customization: Moderate customization based on client needs, requiring specific skills & tools.
- Efficiency Trade-off: Lower efficiency due to unique car-specific repairs, impacting volume.
- Mass Services*
- Customization: Low customization, standardized services for high demand volume.
- Efficiency Trade-off: Focus on high volume, limited individual service options.
- Service Factories*
- Customization: Standardized services and complex back-end operations, high volume.
- Efficiency Trade-off: Limited customization allows for efficient management of complex logistics.
- Mass Customization*
- Customization: Blends high customization with high volume, often using technology.
- Efficiency Trade-off: Both personalized experiences and efficiency through automation.
Servicescape
- Refers to the physical or virtual environment of service delivery, including customer and employee behavior.
- The servicescape influences both the customer and employee experience and should be designed to match the service concept.
- Servicescapes are categorized by who participates (customer, employee, or both) and the complexity (elaborate or lean).
