Study Notes

Operations Management Importance

Operations management (OM) is crucial for adapting to customer preferences, supply chain changes, and evolving work environments.
OM managers address technology, environmental, social, and global challenges.

Defining Operations Management

OM focuses on efficiently converting materials and labor into goods and services to maximize profit.
OM requires a well-defined strategy to manage production and planning.

Operations Strategy

It's a long-term plan that shapes operations capabilities and their contribution to the overall business strategy.
Operations strategy aligns market needs with operational resources.
Performance objectives are set based on market demands.
Resources are strategically deployed to achieve these objectives.

Market-Based vs. Resource-Based Operations Strategy

Market-based focuses on understanding and targeting specific markets and customer needs.
Resource-based focuses on internal strengths and capabilities to establish a competitive edge.
Both approaches are vital for successful operations strategies.

Productivity

Productivity measures the efficiency of turning inputs (labor, capital) into outputs (goods and services).
It can be measured across various levels: individual, workforce, sector, team, national, or global.
Higher productivity supports profitability and business growth.
The formula for productivity is: Output / Input.

Increasing Productivity

Can be achieved through:
- Technological advancements
- Technical efficiency improvements
- Organizational enhancements
- Scale increases

Competitive Priorities

These are the key dimensions/attributes a company prioritizes to compete effectively.
They define a company's positioning against competitors.
Key competitive priorities include:
- Cost: Offering lower-priced products/services
- Quality: Meeting or exceeding customer expectations
- Flexibility: Adapting to changing demands
- Delivery: Delivering products/services quickly and on time
- Innovation: Introducing new products, services, or processes for differentiation

Manufacturing Strategies

Approaches and practices companies use to produce goods efficiently and effectively.
Key manufacturing strategies include:
- Lean Manufacturing: Minimizing waste, maximizing efficiency
- Agile Manufacturing: Emphasis on flexibility and rapid response to changes
- Mass Customization: Combining mass production with customization
- Total Quality Management (TQM): Embedding quality principles in all aspects of production
- Six Sigma: Reducing variation and defects for quality and efficiency
- Just-In-Time (JIT): Minimizing inventory by producing only when needed
- Sustainable Manufacturing: Minimizing environmental impact, conserving resources
- Flexible Manufacturing System (FMS): Automated machines for producing various products
- Continuous Improvement (Kaizen): Collaborative efforts to enhance processes, products, and services
- Make-to-Order (MTO): Manufacturing only after receiving customer orders

Design for Manufacturing (DFM)

Bridges the gap between product design and manufacturing, focusing on making production easier and more efficient.
