QUESTIONS AND VERIFIED ANSWERS
Rather than offering sales promotions, Wal-Mart advertises everyday
low prices (EDLP) to ensure consumers that they are always getting the
lowest possible cost. This strategy mitigates what potential cause of the
bullwhip effect? - ANSWER Price fluctuations and advance buying
Changes in price, such as sales promotions, cause consumers to
advance buy. This will result in a spike in consumer demand, followed by
a decrease, that contributes to the bullwhip effect.
What Waste involves unnecessary motions of employees? - ANSWER
EXCESS MOVEMENT
A business owner who only keeps red pens in the workplace because
that is what is needed is most likely focusing on which 'S' from the 5S's
checklist? - ANSWER SORT
SORT refers to only keeping what is needed in the workplace, in order to
have an efficient workplace.
____________ are expected and cannot be controlled - ANSWER
Random variations
RANDOM (natural) variations occur because any process output follows
a normal distribution curve, thus, there is an expected amount of
deviation outside of the mean.
___________________ have a certain cause that can be fixed or altered
- ANSWER Assignable variations
(NONrandom) the objective of the statistical process control is to present
a statistical signal in response to assignable variation, enabling process
,managers to identify and address the cause. Eliminating assignable
variation is necessary to deliver consistent product or service quality.
Some possible sources of assignable variation are machinery,
manpower, materials, methods and mother nature.
____________________ is continuous data that is measured (weight,
gallons, liters, time, etc) - ANSWER Variable data
_____________ is data that is counted ( # of defects, complaints, etc)
and does not dress the degree of failure. - ANSWER Attribute data
A _______________ is a nonrandom shift in the average of the data in a
control chart - ANSWER mean shift
What describes the bullwhip effect? - ANSWER As you move further
upstream across the supply chain (toward suppliers), the demand
variation grows larger.
The bullwhip effect occurs because as you move further left across the
supply chain, the variation in demand increases. This is the result of a
supply chain where each echelon only communicates with the echelon
above it, causing uncertainty to be compounded.
- it is caused by a lack of communication among the various parts of the
supply chain
- each successive echelon of the supply chain has higher order
variations than the last
- various echelons of the supply chain communicated with each other to
reduce it
- there is wider variation in the orders the further to the left you go along
the supply chain, towards the manufacturers suppliers
, A. The bullwhip effect describes the tendency for larger order size
fluctuations as orders are relayed to the supply chain from retailers.
B. Channel coordination means determining lot sizes as though the full
supply chain was one company.
C. "Bullwhip" fluctuations create unstable production schedules, resulting
in expensive capacity change adjustments.
D. The bullwhip effect can occur only when orders DECREASE
As the number of facilities increases, what relationships occur? -
ANSWER - the inventory costs stay roughly the same with slight
increase around the optimum number of facilities
- the transportation costs initially decrease, but then rise
- the facility costs increase
- the total logistics costs decrease, but then rise after they reach the
lowest point possible.
- response time decreases the time it takes for a retailer to communicate
with consumer
Supply chain management is........ - ANSWER the synchronization of
operations management processes across a network of business.
This involves the flow of materials and services, information and
planning, and finance across entities in the supply chain.
The DMAIC cycle relates to what aspect of TQM? - ANSWER Six
Sigma
