Efficiency vs. Effectiveness: * Efficiency: How productively a business uses its resources (). It aims to minimize waste and time. * Effectiveness: The extent to which a business achieves its stated objectives. Effective operations lead to customer satisfaction and increased sales.
Key Elements of an Operations System
The System Model: The operations system consists of three distinct elements: Inputs, Processes (Transformation), and Outputs.
Inputs: The resources used to produce goods and services. Categories include: * Raw Materials: Resources sourced directly from the earth (e.g., chemicals, oils, gas, pulp, wood). * Capital Equipment: Purchased machinery and tools. * Labour: Human work and effort. * Information: Legal sources, internet data, and specialized knowledge. * Time: Directly linked to money and resource usage. * Money: Capital required for operations.
Processes (Transformation): Actions performed to transform inputs into finished products. Examples include: mixing, designing, baking, computing, assembling, constructing, washing, and cutting.
Outputs: The final products (goods or services) delivered to customers. * Outputs should be of the desired quality and maximize the business’s competitiveness.
Characteristics of Manufacturing vs. Service Businesses
Manufacturing Businesses (e.g., Cadbury, Ford, Yakult): * Tangibility: Produces tangible goods that can be physically touched. * Storage: Products can be stored as inventory for future sale. * Production and Consumption: Usually separate (goods are made, then sold later). * Capital Intensity: Often highly automated with large amounts of machinery. * Customer Contact: Low level of customer contact during production. * Standardization: Outputs are typically standardized and identical (e.g., mass production).
Service Businesses (e.g., Melbourne University, Qantas, Hairdressers): * Intangibility: Produces services that cannot be physically touched. * Storage: Services cannot be stored; they are consumed as they are produced. * Production and Consumption: Often occur simultaneously (e.g., a flight or a haircut). * Labour Intensity: Usually requires high levels of human labor. * Customer Contact: High level of interaction with customers. * Tailoring: Services are often non-standardized and tailored to individual needs.
Case Study: Yakult Honsha: * A manufacturer of probiotic milk beverages ( bottles). * Characteristics: Capital intensive, low customer contact, tangible, standardized outputs.
Case Study: Qantas: * A service business providing domestic and international flights. * Characteristics: Labour intensive (pilots, cabin crew), high customer contact, intangible output (the flight), tailored (seat selection, meals).
Technological Strategies for Operations
Automated Production Lines: A sequence of machines and workstations performing tasks automatically with minimal employee involvement. Employees mainly monitor or perform maintenance. * Efficiency: Increases speed and consistent operation. * Effectiveness: Improves quality and reduces labor costs.
Robotics: Programmable machines capable of performing specific, complex, and repetitive tasks. * Advantages: production, high precision, removes dangerous tasks. * Disadvantages: High initial cost, training requirements, potential redundancies.
Computer-Aided Design (CAD): Software that allows products to be created, modified, and tested digitally before physical production. * Benefits: Streamlines the design process, allows for 3D modeling, and enables easy modifications.
Computer-Aided Manufacturing (CAM): Software used to control machine tools and machinery during the production process. * Benefit: Does not require human resetting of machinery, reducing downtime.
Artificial Intelligence (AI): Systems that mimic human intelligence to solve problems and learn from data. * Applications: Predictive maintenance, process optimization, and automation of repetitive tasks.
Online Services: Using internet-based platforms (websites, apps, cloud storage) to process orders and improve customer convenience.
Materials Management Strategies
Forecasting: Predicting future customer demand using past data and market trends to ensure appropriate material levels. * Inaccuracy Risks: Under-ordering leads to dissatisfaction; over-ordering leads to waste.
Master Production Schedule (MPS): A detailed plan outlining what to produce, in what quantities, and when. * Details Included: Staff needed, goods produced, timing, location, and methods.
Materials Requirement Planning (MRP): An itemized list of materials required to meet MPS targets, accounting for lead times and current stock on hand.
Just In Time (JIT): An inventory control approach where materials arrive only as they are needed for production. * Efficiency: Reduces storage costs and money tied up in inventory. * Disadvantage: High risk if suppliers fail to deliver on time.
Quality Management Strategies
Quality Control (QC): A reactive approach involving inspections at various points to check for defects. Standards are set, outputs are inspected, and faulty goods are discarded.
Quality Assurance (QA): A proactive approach where an external body (e.g., ISO 9001) certifies that the business’s processes meet specific global standards.
Total Quality Management (TQM): A holistic approach where every employee is committed to continuous improvement. * Three Core Principles: Continuous Improvement, Customer Focus, and Employee Empowerment (e.g., Quality Circles).
Waste Minimisation and Lean Management
The Three R’s: * Reduce: Decreasing resources, labor, or time used. * Reuse: Making use of items that would otherwise be discarded. * Recycle: Transforming discarded items into new usable materials.
TIMWOOD (Categories of Waste): Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects.
Lean Management: A system aimed at eliminating waste and maximizing customer value. It is underpinned by the POTZ acronym: 1. Pull: Production is dictated by customer demand. 2. One-Piece Flow: Moving a single product through production stages one at a time. 3. Takt: The speed of production required to meet demand. 4. Zero Defects: Striving for perfection and halting production if any defect is found.
Corporate Social Responsibility (CSR) in Operations
Definition: Commitment to go beyond legal obligations to operate sustainably (socially, economically, environmentally).
CSR for Inputs: Sourcing local products (to reduce the carbon footprint), paying suppliers promptly, and using renewable energy.

Global Outsourcing: Transferring non
Pull System: In a pull system, production is driven by actual customer demand rather than forecasts. This approach allows businesses to minimize excess inventory and only produce what is needed, when it is needed. It helps to respond quickly to changes in customer preferences and avoids overproduction, which can lead to waste.
Takt Time: Takt time is the amount of time available for production divided by customer demand. It sets the rhythm at which products must be completed in order to meet demand without overwhelming the production process. By calculating takt time, businesses can ensure that their production pace aligns with customer needs, promoting efficiency while preventing bottlenecks.
One-Piece Flow: This strategy emphasizes the production of one item at a time through the production process, rather than in batches. The goal is to enhance flow efficiency by reducing wait times between production steps. By processing items individually, the company can improve quality control, reduce lead times, and increase responsiveness to demand, ultimately enhancing operational agility.
