Operations Management Notes – MGMT 102/103

Defining Operations Management

• Operations Management (OM) involves designing, planning, organizing, and revising business practices to achieve maximum efficiency and profitability.

• OM decisions include:

  • which product to produce

  • how large a facility to build

  • how many people to hire

  • what methods to use to control quality

• Inputs and outputs:

  • Inputs: people, capital, and material

  • Transformation process: how inputs are converted to outputs

  • Outputs: services and goods consumed by the public

• Outputs should be worth more to the consumer than the total costs of the inputs.

Inputs, Outputs, and Transformation Process

• Inputs are combined by operations to produce outputs (goods/services).

• People (labor and management) and capital (facilities and equipment) are used to change materials into finished goods or to provide services.

• The value-added nature of outputs is a key measure of operation effectiveness.

Transformation Process and Value Creation

• The transformation process converts inputs into outputs that satisfy customer needs.

• Value creation occurs when outputs exceed input costs from the consumer’s perspective.

Levels of Management in Operations

• Top Level Management:

  • Includes CEO, COO, Presidents

  • Focus on strategic planning, setting overall goals, and high-level decisions

• Middle Management:

  • Bridges strategy and execution

  • Allocates resources and coordinates efforts to meet objectives

• Low Level Management:

  • Supervisors and frontline managers

  • Manages daily tasks and actual work processes

Benefits of Operations Management (Overview)

• Premium quality and product quality

• Increased work efficiency and productivity

• Customer satisfaction

• Reduced operating costs

Product Quality and Competitive Edge

• OM is often the first unit to check product durability and reliability.

• Quality contributes to customer satisfaction and provides a competitive edge.

• Focus on meeting customer needs and post-delivery expectations.

Productivity and Staffing

• Productivity = ratio of Input to Output (as stated in the material):

  • $ext{Productivity} = rac{ ext{Input}}{ ext{Output}}$

• OM ensures appropriate staffing to match resources for maximum output.

• Productivity is achievable through effective operations management.

Customer Satisfaction and Quality Alignment

• Customer satisfaction should be coupled with product quality.

• Satisfied customers help the organization thrive and sustain revenue.

Cost Reduction through Productivity and Quality

• Productivity, quality products, and customer satisfaction reduce servicing costs and waste.

• Proper operations management enables production to meet exact demand, minimizing waste and inventory waste.

Types of Decisions in Operations Management

• Three main types: $Strategic, Tactical, Operational$

• They differ in scope, time horizon, and decision nature:

  • Strategic: long-term, broad impact

  • Tactical: mid-term, translate strategy into actions

  • Operational: short-term, day-to-day decisions

Strategic Decisions

• Scope: High-level decisions with broad organizational impact

• Time Horizon: Long-term (often several years)

• Nature: Fundamental, shape overall direction

• Guiding question: “Where are we going?”

• Examples:

  • Entering a new country or region (affects marketing, operations, logistics, branding)

  • Major investments, risk assessment, long-term planning

  • Goals include increasing market share and global presence, aligning with mission or growth strategy

  • Expanding the business, pursuing digital transformation

• Kiosk in fast-food chains as an example of technology-enabled strategic deployment

Tactical Decisions

• Scope: Mid-range, translating strategy into actionable steps

• Time Horizon: Next few months to a year

• Nature: Made by middle managers; guide departments on achieving goals

• Focus: resource allocation, staffing, scheduling

• Guiding question: “How do we get there?”

• Examples:

  • Supporting strategic goals like maintaining customer satisfaction or boosting sales during peak seasons

  • Planning and budgeting for temporary/seasonal wages

  • Scheduling shifts and determining how many staff are needed

  • Supplier and contract negotiations

• Seasonal employment as a typical tactical scenario

• Example: coffee shop evaluating beans, flavor consistency, and cost per kilo; delivery speed and payment terms; supplier selection

Operational Decisions

• Scope: Day-to-day decisions, routine activities

• Time Horizon: Short-term, daily or weekly

• Nature: Specific, routine, directly impact ongoing operations

• Guiding question: “What do we do today?”

• Examples:

  • Refilling store shelves during peak hours

  • Meeting immediate customer needs and ensuring smooth operations

  • Handling last-minute absentee situations

  • Quick adjustments to maintain service levels

Decision Areas in Operations Management (10 Areas)

• There are 10 decision areas, each crucial for managing a business:

1) Goods and Services

• A business must offer goods and/or services to satisfies customers.

• Decisions cover product features, appearance, materials, quality, and how well offerings meet customer needs.

• Examples: seasonal drinks (e.g., Starbucks) as a product offering

2) Quality Management

• Quality defines customer loyalt

  y beyond initial purchase.

• Involves defining, measuring, maintaining, and improving quality.

• Innovation can boost quality; market research helps identify customer wants and needs.

• Emphasizes that quality drives long-term competitiveness and customer trust.

3) Process and Capacity Design

• Process design affects efficiency and cost; a good process enables better product quality at lower cost.

• Involves structuring operations (layout, equipment, workflow) to meet demand efficiently.

4) Location

• Location influences logistics, costs, and access to suppliers and customers.

• The goal is to minimize costs and improve efficiency by being near suppliers, customers, or distribution centers.

5) Layout Design and Strategy

• Layout should facilitate smooth flow and align with brand identity.

• A well-designed layout reduces confusion and enhances customer experience.

• Emphasizes an efficient, customer-friendly, and brand-consistent physical setup.

6) Human Resources and Job Design

• Despite automation, humans are still needed for many tasks.

• Critical activities: recruiting, training, designing jobs, and maintaining job satisfaction to support efficient operations.

7) Supply Chain Management

• Balance quality and costs when selecting suppliers.

• Manage the flow of goods, information, and relationships with suppliers to ensure timely, cost-effective, and quality inputs.

• Examples: Shopee Philippines (e-commerce) and Puregold (retail/grocery) illustrate supplier relationships

8) Inventory Management

• Inventory issues vary by market but require strategies and planning.

• Influences include weather, supply limitations, and labor.

• Tools and methods (e.g., FEFO) may be used to manage shelf life and product availability

• Examples: POS systems and FEFO (First Expired, First Out) approach

9) Scheduling

• Essential for efficiency: properly schedule and maintain human resources, machinery, or robots.

• Aim: allocate the right people and equipment at the right times to ensure smooth operations, meet deadlines, and maximize productivity

10) Maintenance

• Keeping machines, tools, and facilities in working condition to avoid breakdowns, delays, and safety issues

• Examples: maintenance in transportation and maintenance in the food industry

Practical Implications and Real-World Relevance

• OM decisions impact costs, productivity, and quality across the value chain.

• Decisions at strategic, tactical, and operational levels must be aligned with overall goals and customer needs.

• Effective OM can reduce operating costs, improve product quality, boost customer satisfaction, and drive revenue.

• Organizations should continuously evaluate and adapt processes, layouts, staffing, and supplier relationships to stay competitive.

Key Connections to Foundational Principles

• The transformation of inputs into valuable outputs is central to operations theory.

• Balance between cost, quality, speed, and flexibility underpins OM decisions.

• Quality management and customer satisfaction are tightly linked to long-term competitiveness.

• The configuration of processes, layout, and location directly affects efficiency and service levels.

Mathematical and Conceptual Notes

• Productivity definition given in the material: $ext{Productivity} = rac{ ext{Input}}{ ext{Output}}$ (ratio of input to output)

• Decision types can be summarized as:

  • $Strategic$: long-term, broad impact, high investment

  • $Tactical$: mid-term, translates strategy into actions

  • $Operational$: short-term, day-to-day execution

• The slide structure emphasizes value creation: quality, efficiency, and customer satisfaction drive profitability and sustainability.
