What is Operations?
Make/create
The Transformation of Inputs into Outputs
Operations refers to manufacturing andservice processes used to transform the resources employed by a firm to a product desired by customers.

Service-commodity goods continuum
A restaurant provides a physical good (the food), but also provides services in the form of ambience, the setting and clearing of the table, etc
Product-service bundling: refers to a company building service activities into its product offerings for its current users.
Operations Management & Service
Traditionally, operations management has been associated with physical goods
But services, the provision of intangibles to customers, is a larger share of the economy
Services moved from about 60% of the Canadian GDP to about 65% from 1970 to 1991
GDP composition by sector:
200520092012
Agriculture: 2.2% 2.3% 1.8%
Manufacturing: 29.4%26.4% 28.6%
Services: 68.4%71.3%69.6%
Services versus Goods
A service is an economic activity where an immaterial exchange of value occurs. A service is
Intangible: they can not be touched, gripped, tasted, looked at, etc. Thus neither potential nor need for transport, or storage.
Perishable: An empty seat on a plane never can be utilized and charged after departure.
Inseparable: Service requires some degree of interaction with customer. The hairdresser or the pilot must be in the same shop or plane with customer, respectively, for delivering the service.
Heterogeneous: Each service is unique. It is one-time generated, rendered and consumed and can never be exactly repeated.
Evaluated as a package: evaluated considering (a) supporting facilities (b)facilitating goods (C implicit and explicit services

Management
Operations Management: The management (design, operation and improvement) of the transformation processes that create value (= quality / price).
The Process View of organizations
What is a process?
A set of tasks that transform inputs into outputs
Every organization has several processes that work to transform inputs into outputs.
These processes can be analyzed at different levels of detail
Their management can be different depending on the overall objective or strategy of the business.
Levels of detail in process analysis
Each process consists of several sub-processes
Make/create
Which processes are we interested in?
Operations management studies the planning, buy, make/create, Delivering (sell and moving) and returning of processes.
Planning: processes that need to operate an existing supply chain process
Sourcing: Selection of suppliers that deliver goods and services required to create firms product.
Make/create: Manufacturing/Production
Delivering: Logistics and selling
Returning: processes for receiving defective products from customers.

How do we measure process performance?
How do you a know a process is performing well?
Efficiency vs. Effectiveness
Efficiency:
Doing something at the lowest possible cost.
How well are inputs transformed into outputs?
Effectiveness:
Doing the right thing to create most value.
How far is a stated objective achieved?
Example: TD Bank
Efficient: using fewest people possible at counter
Effective: minimize time customers need to wait
More Examples of:
Efficiency vs. Effectiveness
EfficiencyEffectiveness
Washing MachineEnergy consumption per cycleCloths clean?
Do they smell so bad?
CarFuel consumptionToo small (5 mpg)?
Managers need to find the right balance!
How to measure Efficiency?
Productivity is a common measure on how well resources are being used.
Broadest sense, it is defined as the following ratio:
Our goal is to make this ratio as large as practical.
Productivity: measures how well a business unit is using its resources. Productivity is a relative measure (can be compared either with other similar operations, or over time within the same operation).
Productivity Measures
Partial measure of productivity (PMP):
For example, Labor productivity = Output/Labor
(Ex: Car Manufacturer: vehicles per man shift)
Multi-factor measures of productivity (MFP):
Output/(Labor + Capital + Material)
Total Factor Productivity (TFP):
Includes all factors of production
Output/(All Input)
Partial Measure of Productivity (PMP): When we are concerned with the ratio of output to a single input (e.g., output per labor, or output per worker per hour).
Multifactor Productivity Measure (MPM): If we want to look at the ratio of the output to a group of inputs (but not all) (We should unify input units when we combine for example in dollars).
Total factor measure of Productivity(TFP): When we want to express the ratio of all outputs to inputs. (We should unify input units when we combine for example in dollars).
Productivity: Example
A company that makes candles, has 2 workers. Each worker produces an average of 20 candles per hour. Labor cost is $10 per worker hour, and machine cost is $20 per hour.
Calculate labor productivity. Use candles per worker hour as the measure of labor productivity.
Calculate the multifactor productivity. Use candles per dollar cost (labor plus machine) as the measure.
Company decided to hire 2 new workers. The workers still produce 20 candles per hour. Do you think the multifactor productivity would change?
20 candles per worker per hour.
20*2/(2*10+20)=1 candle per dollar cost
How to tell a process is effective?
Low cost process
High quality process
Fast delivery process
Change in volume
Flexible Process
Technical support
After sale support
Environmental impact
Performance objectives/targets:
What is a Good Process?
Productivity
Maximize output for a given amount of input
Efficiency
Minimize cost for a given amount of input
The Efficiency View
The Strategic View
Effectiveness
Match supply and demand at the lowest cost!
What is a Good Process?
Compatible
What is Good OM?
Trade-offs and Innovation
Improvement
Innovation
Productivity
Taxonomy of process types: competing firms
Effectiveness and efficiency are usually competing objectives.
Frontiers firms: firms that dominate other firms either in productivity or effectiveness.
Firms try to locate on the frontier and find a right balance between effectiveness and productivity.
Innovation in operations management pushes the envelope, i.e., move the frontier.
What can go wrong?
Processes can be poorly designed & not effective
The process might not fit the strategic business objective
Example: Waiting 30 minutes for your coffee.
Processes can be inefficient
There is a mismatch between supply and demand
Example: How many people need to make a latte?
Ideally, processes should be designed and managed to efficiently meet the demands placed on it.
Processes should also be run so that the overall business objectives are met.
In 2006, when Nintendo launched the Wii console, many customers had to wait several weeks to purchase the product. In fact, many units were resold online for several hundred dollars over the retail price.
In the 2002-2003 flu season, 95 million doses of flu vaccine were produced but demand was much lower and excess vaccines had to be destroyed. In the next season, insufficient vaccines were available and there were widespread shortages.

Why do these problems occur?
Making sure that your processes work perfectly is NOT EASY!
The business world is full of uncertainties.
Some companies manage their processes much better than their competitors and this gives them a huge advantage in the marketplace.
Airline Industry

In 2005, Southwest Airlines posted a profit for its 33rd consecutive year (or the 132nd consecutive quarter)
In the first half of 2005, the ten largest airlines lost a combined US$10 billion (CDN $11 billion).
Some airlines even filed for bankruptcy protection
Many airlines underwent massive efforts to restructure their entire business model!
Airline Industry Continued
Southwest says that if its boarding times increased by 10 minutes per flight, it would need 40 more planes at a cost of $40 million each to run the same number of flights it does currently. textbook
Can they do better?

What did airlines do to survive?
They now charge to check-in baggage

Dynamic pricing: The price you pay for a ticket depends on when you buy it!
Dynamic Pricing (Time)
Lets compare the price of each ticket that is sold:
An airline ticket 1 year from departure
An airline ticket 1 week from departure
Round trip flight from Toronto to Calgary:
$450/ticket 1 year from departure
$503/ticket 1 week from departure
Round trip flight from Toronto to Rome:
$1115/ticket 1 year from departure
$1991/ticket 1 week from departure

Why study operations?
Managing the core process is important for all firms.
Companies with good operations are doing much much better than others.
Routinely in large organizations the COO will be the heir apparentto the CEO. wiki
Operations management principles are being applied to other areas such as marketing & finance.

Lessons & Summary
OM is the management of the core activity of any company (i.e., the creation of goods and services) and is critical to the performance of an organization.
More visible measures of performance (e.g., profits, return-on-assets, customer satisfaction) directly depend on how well the system, and each individual process, process is managed.
Management of the underlying processes that create the goods and services are critical to the performance and long-term sustainability of an organization.
What is a good process?

(Productivity vs. Quality)
