Operations Management in TQM
uniformity of input
*) Service operations are often subject to a higher degree of variability of inputs. *) Each client, patient, customer, repair job, and so on presents a somewhat unique situation that requires assessment and flexibility. *) Conversely, manufacturing operations often have a greater ability to control the variability of inputs, which leads to more-uniform job requirements.
organizing
Decree of centralization, subcontracting
controlling
Inventory control, quality control
labor content of jobs
Services often have a higher degree of labor content than manufacturing jobs do, although automated services are an exception.
system
a set of interrelated parts that must work together
inventory models
also popular after some early work, went through a long period of low interest but are now widely used to control inventories
linear programming
and related mathematical techniques are widely used for optimum allocation of scarce resources.
schematic model
are more abstract than their physical counterparts; that is, they have less resemblance to the physical reality.
mathematical models
are the most abstract: they do not look at all like their real-life counterparts. Examples include numbers, formulas, and symbols.
Project models
are useful for planning, coordinating, and controlling large-scale projects. (PERT and CPM)
Operations Management
at the core of all business organizations
community
being a good neighbor
planning
capacity, location, products and services, make or buy, layout, projects, scheduling
finance
comprises of activities related to securing resources at favorable prices and allocating those resources throughout the organization
management information system (MIS)
concerned with providing the management the information it needs to effectively manage; helps firm to realize maximum benefit from investment
Operations
consists all of activities directly related to producing goods or providing services
operations
core of most business organization; responsible for creation of good or services
statistical models
currently used in many areas of decision making.
hiring and firing workers
don't hire under false pretenses (e.g., promising a long-term job when that is not what is intended)
economic analysis of investment proposals
evaluation of alternative investments in plant and equipment requires input from both operations and finance people
service oriented
exists in areas such as healthcare, transportation, food handling, etc.
goods-oriented
exists in both manufacturing and assembly operatioons
Marketing
focus on selling and/or promoting the goods or services of an organization
maintenance
general upkeep or repair of equipment
lead time
gives customers realistic estimates of how long it will take to fill their order; time between ordering a good or service and receiving it
standardized output
high degree of uniformity in goods or service
staffing
hiring/laying off, use of overtime
quality
honoring warranties, avoiding hidden defects; :
service operation
implies on act
quality assurance
in many instances, customers receive the services as it is performed
directing
incentive plans, issuance of work orders, job assignments.
system operation
involves management of personnel, inventory planning and control, scheduling, project management, and quality assurance
service
is act oriented
system approach
is almost always beneficial in decision making; essential whenever something is being designed, redesigned, implemented, improved, or otherwise changed.
model
is an abstraction of reality, a simplified version of something.
manifacturing
is good oriented
budgeting
it must be periodically to plan financial requirements; must sometimes be adjusted, and performance related to budget must be evaluated
design people
long term (in marketing)
physical models
look like their real-life counterparts.
uniformity of output
manufacturing tends to be smooth and efficient because of high mechanization generates product with low variability; services appear to be slow and awkward
quantitative approach
may be emphasized at the expense of qualitative information. Models may be incorrectly applied and the results misinterpreted.
measurement of productivity
more straightforward in manufacturing due to high degree of uniformity of most manufactured items; in service, it is more difficult
provision of funds
necessary funding of operations and the amount and timing of funding can be important and even ctricial when funds are tight
environment
not doing things that will harm the environment
Management Information System (MIS)
occurs mainly through designing systems to capture relevant information & designing reports
industrial engineering
often concerned with scheduling, performance standards, work methods, quality control, and material handling
worker safety
providing adequate training, maintaining equipment in good working condition, maintaining a safe working environment
product safety
providing products that minimize the risk of injury to users or damage to property or the environment
personnel or human resources
recruitment or training of personnel
system design
relate to system capacity, the geographic location of facilities, arrangement of departments and placement of equipment within physical structures, product planning, and acquisition of equipment
purchasing
responsibility for procurement of materials, supplies, and equipment

results in a tangible output
customer contact
service involves much higher degree of customer contact than manufacturing
Distribution

term used to describe the difference between the cost of inputs and the value or price of outputs
operations manager
the key figure in the system: he or she has the ultimate responsibility for the creation of goods or provision of services.
Operations Management
the management system or process that creates goods and/or provides services
Degree of Standardization
the output of production systems can range from highly standardized to highly customized
customized outputs
the product or service is designed for a specific case or individual
for-profit organization
the value of output is measured by the prices that customers are willing to pay for the goods or services
operations manager
they must coordinate the use of resources through the management of planning, organizing, staffing, directing, and controlling
nonprofit organization
value of outputs is their value to the society
Pareto phenomenon
which means that all things are not equal; some things (a few) will be very important for achieving an objective or solving a problem, and other things (many) will not. The implication is that a manager should examine each situation, searching for the few factors that will have the greatest impact, and give them the highest priority.
queuing techniques
which originated around 1920 in the telephone industry but remained dormant until the 1950s and 1960s, are useful for analyzing situations in which waiting lines form.
