This combines and transforms various resources used in the production/operations subsystem of the organization into value added products/services in a controlled manner as per the policies of the organization.
Production/Operations Management
What is the main purpose of Production/Operations Management?
To transform resources into value-added products or services in a controlled and organized manner.
What are the major areas under the scope of Production/Operations Management?
Location of facilities
Maintenance management
Material management
Quality control
Production planning and control
Process design
Product design
Plant and layout material handling
This is a set of interrelated management activities involved in manufacturing products.
Production Management
What are the objectives of production management?
To produce goods or services of the right quality and quantity at the right time and right manufacturing cost. (QQTC)
Right quality
Right quantity
Right time
Right cost
The quality of the product is based on:
customer needs
cost of the product
Manufacturing costs should be established __ (before/after) production.
Before
Part of an organization concerned with transforming inputs into outputs (products) with the required quality level
Production function
It is the step-by-step conversion of one form of material into another through chemical or mechanical processes.
Production
What does production do to a product?
creates or enhances its utility
The process by which goods and services are created.

resource allocation
What are the two basic questions in a Basic Allocation Decision?
Which activities/projects to fund
How munch funding to allocate
What is the goal of the Basic Allocation Decision?
To obtain the maximum from available resources while minimizing resource loss
A priority ranking of items excluded from the original plan, indicating what should be funded if additional funds become available.
contingency mechanism
An index that measures output relative to the input used to produce them
Productivity
What is the basic formula for productivity?
Productivity = Output/Input
A productivity measure based on a single input.
Partial productivity
A productivity measure based on a more than one inputs.
multi-factor productivity
A productivity measure based on all inputs.
Total productivity
What are the 3 types of productivity measures based on inputs?
partial
multifactor
total
Why are productivity measures useful?
track performance over time
judge performance of an industry
show how effectively an org uses resources
What are the factors that affect productivity?
Methods
Management
Capital

Technology
How to improve productivity?
Develop productivity measures for all operations.
Look at the system as a whole and identify critical operations.
Ask workers at all organizational levels for ideas on improving productivity.

bottleneck
When does a bottleneck in production occur?
When a resource has a less capacity than what is needed to meet demand
What are the effects of a bottleneck on production efficiency?
The stages before the bottleneck must slow down production.
The stages after the bottleneck must function below their capacity.
How to solve bottleneck problems?
Adjust the production level in the sequence where the bottleneck is happening
This determines the effective capacity of the overall production process.
