Study Notes

Operations Management and TQM

Material Requirement Planning (MRP): A computer-based inventory management system that helps production schedule and order dependent demand items (components of finished goods). Dependent demand items' inventory quantities depend on production levels of the final product. MRP breaks down demand requirements for finished goods into lower-level components, identifies quantities, and schedules timing for each component.
MRP Attempts to Solve: Sets up schedules for components and effectively controls the requirements for each department's items.

Master Production Schedule (MPS)

Conventional Inventory System: Includes ABC Classification, Reorder Models, and Safety Stock calculations.
MRP Concept: Focuses on Independent and Dependent Demand, Lumpy Demand, and Lead Times. Includes Common use items.

MRP Process

MRP Inputs: Master Production Schedule, Product Structure Records, and Inventory Status Records.
MRP Outputs: Determines gross quantities of components required from product structures. Gross material requirements are determined after subtracting the inventory on hand and adding in safety stock.

MRP WHERE TO USE IT

Industries: Useful for fabricating and assembling products (automobiles, tractor-trailer equipment, rail coaches).

Functions of MRP

Forecasting: MRP requires manufacturing activities like inventory, production schedule, and customer demand. Forecasting the level at which inventory should be purchased and manufactured.
Reducing Waste: Reduces the amount of unused materials and products. Combines current production levels and customer demand to optimize material and finished product levels.
Floor Control and Scheduling: Manages and maintains shop floor control and manufacturing scheduling. When adjustments are needed, the MRP system automatically makes those necessary changes.

Bill of Material (BOM)

Definition: A detailed list of materials and parts needed for a specific job or production run. The Bill of Materials is a printed or duplicated form.
BOM Solutions Capabilities: Provides support for single and complete BOM definitions, BOM audit and analysis capabilities, product configuration management, context management, extended lifecycle support, and open application and system integration.
BOM Solutions Benefits: Reduces complexity by eliminating the need for multiple BOM systems; ensures accuracy and completeness.

Quality Assurance and Control

Quality Assurance (QA): A broad practice aiming to ensure the quality of products/services. It focuses on preventing defects.
Quality Control (QC): Focuses on inspecting/detecting defects.

Quality Control

Definition: Techniques and activities to fulfill quality requirements. Focuses on the inspection aspect of quality management to identify defects after the product is made.

Quality Management System (QMS)

International Organization for Standardization (ISO) 9000: Framework that defines standards for quality management systems. Organizations document and implement procedures to consistently meet and exceed customer/stakeholder needs.

Eight Quality Management Principles

Customer focus: Understanding and meeting customer needs.
Leadership: Leaders establish unity of purpose and direction and supports employees.
Involvement of people: Employees are the key driving force for quality improvement.
Process approach: Managing interconnected processes to deliver value.
System approach to management: Looking at interactions of the whole system to drive improvements.
Continual improvement: Creating a culture of improvement to achieve higher levels of performance over time.
Factual approach to decision making: Making decisions based on documented evidence, rather than judgment or guess work.
Mutually beneficial supplier relationships: Working with trusted suppliers to maintain quality and consistency.

Quality Levels

Points to remember: Quality products and services meet expectations and help satisfy needs not currently being met. At the process level, what products or services are the most important to customers , what steps produce the services, what is the input for the process that produces those results, and which processes are most significant to performance results.

Quality Costs

Framework: Identifying quality components related to producing high-quality products (and low-quality items), with the goal of minimizing the total cost of quality. Costs of poor quality include costs to detect/appraise, internal failure costs, and external failure costs.
