Lecture Notes: Operations Management

Introduction to Operations Management

  • Operations management is a fundamental business function.
  • Businesses convert inputs from the environment into outputs (products/services).
  • Goal: Achieve profitability by managing the transformation process effectively and efficiently.

Importance of Effective and Efficient Operations Management

  • Efficiency: Doing the best with the least resources.
    • Reducing waste and mistakes.
    • Enhancing productivity with minimal resources.
  • Effectiveness: Meeting objectives, like enhancing quality and customer satisfaction.
  • Benefits:
    • Reducing costs and increasing revenue.
    • Lower investment needs and encouraging innovation.
    • Improving productivity and profitability.

Key Terms in Operations Management

  1. Operations Function: Utilization of resources to create products/services.
  2. Operations Managers: Individuals responsible for managing the operations function at various organizational levels.
  3. Operations Management: Encompasses activities, decisions, and responsibilities tied to managing the operations process, including transforming inputs into outputs.

Differences Between Products and Services

  • Products: Tangible, can be kept in stock, quality is measurable.
  • Services: Intangible, perishable, quality is subjective.

Operations Management Strategies and Performance Objectives

  • Focus on customer needs and formulating strategies.
  • Key elements:
    1. High quality
    2. Lower costs
    3. Shorter lead time
    4. Greater adaptability
    5. Lower variability
    6. Higher level of service
  • Objectives designed to achieve these elements can improve competitive positioning.

Classification of Process Types

For Manufacturers

  1. Project Processes: Unique, large-scale, long duration (e.g., stadium construction).
  2. Jobbing Processes: Small scale, low volume, specific requirements (e.g., custom cakes).
  3. Batch Processes: Production in batches or lots (e.g., limited range manufactured in lots).
  4. Mass Production: Producing identical products in large quantities.
  5. Continuous Processes: Continuous, uninterrupted production unless stopped for valid reasons.

For Service Providers

  1. Professional Services: High client contact, few recipients at a time (e.g., doctors).
  2. Service Shops: Intermediate client contact, standardized services (e.g., hotels).
  3. Mass Services: Less client contact, many recipients at once (e.g., broadcasting).

Operations Design

  • Encompasses product/service design and process design.
  • Product Design Steps:
    1. Idea generation
    2. Concept screening
    3. Preliminary design
    4. Evaluation and improvement
    5. Final design (prototype)
  • Components: Concept package, composition, and process.
  • Operations Process Design: Involves layout selection (e.g., fixed position, process, product, cellular types), and considering technology and job design.

Operations Planning and Control

  • Reconciling supply with demand in terms of volume, timing, and quality.
  • Key activities:
    1. Loading of tasks
    2. Sequencing of tasks
    3. Scheduling of tasks
  • Capacity Planning: Adjusting capacity to meet demand.
    • Strategies: Level capacity plan, chase demand plan, demand management plan.

Quality Management and Improvement

  • Consistent conformance to customer expectations.
  • Eliminating the quality gap.

Quality Planning and Control Steps

  1. Define quality characteristics.
  2. Measure quality.
  3. Control quality.
  4. Improve quality.
  • Total Quality Management (TQM): Involves everyone in the business focusing on quality.

Performance Standards and Improvement

  • Types of Performance Standards:
    1. Historical standards
    2. Target standards
    3. Competitor standards
    4. Absolute standards
  • Improvement Approaches:
    • Breakthrough improvement (drastic changes).
    • Continuous improvement or Kaizen (incremental changes).

Managing Failures

  • Types of failures: Design, facility, staff, supplier, customer.
  • Detecting, analyzing, and recovering from failures.

Conclusion

  • Focus on designing, planning, and improving operations.
  • Operations strategies should consider customer needs and the overall business strategy.
  • Emphasizing quality and continuous improvement in operations management.
