Constraint Management
Process Layout
Lean Systems
Supply Chain Strategy
Location
Inventory Management
Forecasting
Sales and Operations Planning
Resource Planning
Scheduling
Operations Management is:
The systematic design and control of processes that transform inputs into services and products for internal and external customers.
Operations Management can be viewed through different lenses:
Addresses issues related to the transformation process converting inputs to useful outputs that yield revenue for the system.
Defined as a system where several activities are performed to transform inputs into outputs using a transformation process.
Key Characteristics:
Transforms a set of inputs into output.
Employs a systematic approach to handle transformation issues and improve efficiency.
Various sectors include:
Construction
Health Care
Manufacturing
Retailing
Transportation
Wholesaling
Common functions across these sectors:
Accounting
Distribution
Engineering
Operations
Finance
Human Resources
Marketing
Processes are essential and should add value.
Can be divided into sub-processes, referred to as nested processes.
Each process has identifiable inputs and outputs.
External Customers: Purchase goods/services.
Internal Customers: Receive outputs from processes within the organization.
Manufacturing Processes improve physical dimensions of products:
Changes in properties, shapes, finishes, or joining materials.
Service Processes do not transform material in such ways, focusing instead on providing intangible services.
Manufacturing Organizations vs. Service Organizations:
Physical, durable products vs. Intangible, perishable products.
Inventoried outputs vs. Non-inventoried outputs.
Low customer contact vs. High customer contact.
Regional vs. Local markets.
Large facilities vs. smaller facilities.
Capital vs. Labor intensive.
Quality measurements differ across sectors.
Both sectors must focus on quality, productivity, customer response, resource planning, and demand estimation.
Value chains consist of interrelated processes producing services/products satisfying customer needs.
Distinction between core processes (directly deliver value) and support processes (facilitate core functions).
Customer Relationship Processes: Attract and build relationships with customers.
New Service/Product Development: Design based on external customer feedback.
Order Fulfillment Processes: Execute service/product delivery.
Supplier Relationship Processes: Manage supplier interactions and item flows.
Support processes are essential for the operation of core processes.
Include relationships with external suppliers and customers.
Steps for effective decision-making:
Recognize and define the problem.
Collect necessary information for analysis.
Choose the most effective alternative.
Implement the selected solution.
Strategic Decisions: Capabilities development, process design, and performance measures.
Tactical Decisions: Project planning, inventory management, and resource scheduling.
Productivity as:
Output value (services/products) divided by input resources (labor, materials, etc.).
Single Factor Productivity:
Example: Three employees process 600 policies in a week (5 policies/hr).
Multi-factor Productivity:
Example: 400 products valued at $10 each, actual costs calculated for productivity measurement.

Problems include calculation of labor and multifactor productivities based on given data.
