In-Depth Notes on Process Strategy and Technology in Production

Learning Objectives

  • Describe four process strategies.
  • Compute crossover points for different processes.
  • Utilize tools of process analysis.
  • Describe customer interaction in service processes.
  • Identify recent advances in production technology.

Global Company Profile: Harley-Davidson

  • A leader in the motorcycle industry emphasizing:
    • Quality and lean manufacturing principles.
    • Materials as Needed (MAN) system.
    • Various product configurations.
    • Tightly scheduled production lines.

Four Process Strategies

  • A process strategy defines how a product is produced or how a service is provided.
  • Strategies have long-term effects on:
    • Efficiency
    • Production flexibility
    • Costs
    • Quality

Types of Process Strategies

  1. Process Focus

    • Organized around specific activities or processes.
    • High degree of product flexibility using general-purpose equipment.
    • High costs, low equipment utilization; variable product flows.
  2. Repetitive Focus

    • Assembly line organization, facilities characterized by modularity.
    • More efficient than process-focused, with limited flexibility.
    • Example: Harley-Davidson uses modules for multiple motorcycle configurations.
  3. Product Focus

    • Facilities organized by product lines, high volume but low variety.
    • Long, continuous production runs improve efficiency with less skilled labor.
    • Example: Frito-Lay's snack production.
  4. Mass Customization

    • Combines flexibility of process focus with efficiency of product focus.
    • Example: Dell Computer's customizable PCs.
    • Requires efficient product design, tightly controlled inventory, and responsive supply chains.

Process Comparison

  • Characteristics vary by process type:
    • Process Focus: Low volume, high variety; skilled operators, high raw material inventories.
    • Repetitive Focus: Modular outputs; training reduced through repetitive operations.
    • Product Focus: High volume, low variety; costs managed through fixed and variable expense balancing.
    • Mass Customization: High variety, low fixed costs; requires extensive training for customization.

Tools of Process Analysis

  • Flow Charts: Visual depiction of material movement.
  • Time-Function Mapping: Displays processes over time, showing delays.
  • Value-Stream Mapping: Analyzes flows and value addition across the supply chain.
  • Process Charts: Symbolic representation of key activities in a process.
  • Service Blueprinting: Focuses on customer and provider interactions.

Special Considerations for Service Processes

  • Importance of customer interaction in the design of service processes:
    • Needs to improve efficiency without adversely affecting performance.
    • Finding a balance between cost efficiency and customer interaction.

Technology in Services

  • Technologies impact across various sectors:
    • Financial Services: ATM, online banking, etc.
    • Education: Online assignments, interactive tools.
    • Restaurants: Wireless ordering, transponders for tracking sales.
    • Health Care: Robotic surgeries, online monitoring.

Recent Advances in Production Technology

  • Machine Technology: Increased precision and productivity, reduced environmental impact.
  • Automatic Identification Systems (AIS): Use of bar codes and RFID for improved data entry.
  • Process Control: Real-time monitoring using sensors and computers.
  • Vision Systems: Aid in inspection and quality assurance.
  • Robotics: Enhanced efficiency and safety by performing dangerous or monotonous tasks.
  • Automated Systems: Systems for storage, retrieval, and material handling.
    • Example: Automated Guided Vehicles (AGVs) enhance mobility in production areas.
  • Computer-Integrated Manufacturing (CIM): Integrates all aspects of production including engineering and supply chain.
