    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).
