what is operations?
the part of. abusiness organzation that is responsible for producing goods or services
oprations management- the management of systems or processes that create goods and or provide services
supply chain - a sewuence of avctivties annd organzations involved in producing and derlievring a good or service
role of the operations manager
the operations function consists of all activties directly related to rpoducing goods or providing services
a priamry function of the opertions manager is to gudie the system by decision making

why some organzations fail
1 Neglecting operations strategy
2. Failing to take advantage of strengths and opportunities
and/or failing to recognize competitive threats
3. Too much emphasis on short-term financial
performance at the expense of R&D
4. Too much emphasis on product and service design and
not enough on process design and improvement
5. Neglecting investments in capital and human resources
6. Failing to establish good internal communications and
cooperation
7. Failing to consider customer wants and needs
define the terms mission and stragety and exaplin why they are important
mission: the reason for an oraganzations existence
strategy: a plan for achieving organzational goals
serves as a roadmap for reaching the organzational desitinations
order qualifers
minmium standard of accepabiltiy for a product or service to be considered as a potential for purchase
order winners
good or services that cause it to be perceived as better than competition
define the temr producifvity and explain why it is imporant to organzations
producitvity a measure of the effective use of resources, usally expressed as the ratio of of output to input
High productivity is linked to higher standards of living
As an economy replaces manufacturing jobs with lower
productivity service jobs, it is more difficult to maintain high
standards of living
Higher productivity relative to the competition leads to
competitive advantage in the marketplace
Pricing and profit effects
For an industry, high relative productivity makes it less
likely it will be supplanted by foreign industry

Features Common to All Forcasts
Techniques assume some underlying causal system
that existed in the past will persist into the future
Forecasts are not perfect
Forecasts for groups of items are more accurate than
those for individual items
Forecast accuracy decreases as the forecasting
horizon increases
forecasts are not perfect
becasue random variation is always present, there will always be some residual error, even if all other factors have been accounted for.
Elements of a Good Forecast
Should be timely
Should be accurate
Should be reliable
Should be expressed in meaningful units
Should be in writing
Technique should be simple to understand and use
Should be cost-effective
Steps in the Forecasting Process
1. Determine the purpose of the forecast
2. Establish a time horizon
3. Obtain, clean, and analyze appropriate data
4. Select a forecasting technique
5. Make the forecast
6. Monitor the forecast errors
four qaulative forecasting techinques
Forecasts that use subjective inputs such as opinions from consumer
surveys, sales staff, managers, executives, and experts
Executive opinions
A small group of upper-level managers may meet and collectively develop a
forecast
Salesforce opinions
Members of the sales or customer service staff can be good sources of
information due to their direct contact with customers and may be aware of
plans customers may be considering for the future
Consumer surveys
Since consumers ultimately determine demand, it makes sense to solicit input
from them
Consumer surveys typically represent a sample of consumer opinions
Other approaches
Managers may solicit 0pinions from other managers or staff people or outside
experts to help with developing a forecast.
The Delphi method is an iterative process intended to achieve a consensus
reverse engineering
dismantling and inspecting a competitors product to dicsover product improvements
the 3rs are redue, resue, and recyle
quality function deployement (QFD) is structured approach for integrating the voice of the consumer into the product development process
what does product and service design do?
Translate customer wants and needs into product and
service requirements
2. Refine existing products and services
3. Develop new products and services
4. Formulate quality goals
5. Formulate cost targets
6. Construct and test prototypes
7. Document specifications
8. Translate product and service specifications into process
specifications
9. Involve inter-functional collaboration
strategic producrt and service design is the essennce of an organzation is the goods and services it offers
key questions of product and design
is there a demand for it?
can we do it?
what level of quality is appropriate?
does it make sense from an economic standpoint?
reasons for design and redesign
economic
social and demogrpahic
political, liability, or legal
competitve
cost or availability
technological
reverse engineering: dismantling and inspecting a competitors product to discover product improvements
legal and ethical product and services
product liability
ligitation
legal and insurance costs
settlement costs
costly product recalls
reputation effects
unifomrm commerical code
ethical considerations
deisgners are often in. stress
these pressures force trade off decisons
human factors
cultutral factors

cradel to grave assessment
aka life cycle analysis: the assessement of the enivromentla impact of a product or service throughout its useful life
standardization: extent to which there is an absence if variety in a product, service, or process
kano model, basic quality ( customer requirments that have only limited effect on customer stastifaction), performance quality ( customer requirements that generate satisfaction or dissatisfaction), excitement quality ( feature or attribute that was unexpected by the customer and causes excitement)
concurrent engineering: bringing engineering design and manufacturing personnel together early in the design phase
key issues in service design- degree of variation in service requirements, degree of customer contact and involvement
phases in service design process
1. Conceptualize
• Idea generation
• Assessment of customer wants/needs
• Assessment of demand potential
2. Identify service package components needed
3. Determine performance specifications
4. Translate performance specifications into design
specifications
5. Translate design specifications into delivery
specifications

Consistent with the organization mission
User-friendly
Robust if variability is a factor
Easy to sustain
Cost-effective
Has value that is obvious to the customer
Has effective linkages between back- and front-of-the-
house operations
Has a single, unifying theme
