Without calculating the EOQ, how can you conclude from these two calculations that the current lot size is too large? 

 A. There is not enough information to determine this.

 B. When Q 490, the annual holding cost is less then the ordering cost, therefore Q is too small.

 C. When Q 490, the annual holding cost is larger than the ordering cost, therefore Q is too large. 

 D. Both quantities are appropriate 


e. What would be the annual cost saved by shifting from the 490-bag lot size to the EOQ? 

The annual holding cost with the EoQ is S 708.69. (Enter your response rounded to two decimal places.) 

The annual ordering cost with the EOQ is $ 709.65. (Enter your response rounded to two decimal places.) 

Therefore, Sam's Cat Hotel saves $ 14.25 by shifting from the 490-bag lot size to the EOQ. (Enter your response rounded to two decimal places.)

Audit sampling involves applying an audit procedure to less than 100 percent of the population for the purpose of evaluating some characteristics of the population.

Audit sampling involves applying an audit procedure to less than 100 percent of the population for
the purpose of evaluating some characteristics of the population. The fact that an audit involves
sampling is noted in the scope paragraph of the auditor’s report, which contains the phrase “An
audit includes examining, on a test basis.” When an auditor uses sampling, an element of
uncertainty enters into the auditor’s conclusions.
Required:
a) Explain why auditor’s still use sampling techniques despite the uncertainties that are
inherent in audit conclusions drawn on samples.
b) As an auditor what will be your justification for using statistical sampling instead of nonstatistical
sampling in auditing account receivables. Give three justifications
c) Outline five quality control procedures the auditor may implement to ensure that the
auditors work is of standards.
d) You overheard the following comments during a conversation between Auditor Kaakaba
and Auditor Kasanga about a specific sampling application.
i. “Using non-statistical sampling is so much easier than using statistical sampling.
Statistical sampling requires far too many judgments. Under non-statistical
sampling, I can just pick items, evaluate them, and make my decision.”
ii. “I wish non-statistical sampling were allowable in generally accepted auditing
standards audits. In some cases, the additional time required by statistical sampling
just isn’t worth the benefits.”
iii. “Once we control the sampling risk, we’re home free. Assuming we select a
representative sample, there’s nothing else that we need to worry about.”
iv. “Be careful if you try to set sampling risk at too low a level. You will need to select
more items, which will increase the amount of audit time.”
v. “Those transactions with Wimbey are always so difficult to audit. Let’s exclude
them from our sampling frame. We can pick other items and have a sufficiently
large sample to meet generally accepted auditing standards.”
vi. “I’m about to perform a walkthrough on Flushing’s processing of sales transactions
to understand their nature. What level of sampling risk should I consider in planning
my sample of transactions?”
Required:
With reference to appropriate professional standards and practices state whether each of the
above statements is valid or not a valid and why you think so. Your responds must be very
brief.

Gilmore Framing (GF) specializes in framing artwork for mid-sized commercial projects. Its clients are largely brokers who contract to provide “art” to decorate new or renovated hotels. The brokers send the unframed artwork to GF to mount and frame.

The process at GF involves two steps, Frame Construction and Mounting. There is one Frame Construction Station and one worker at Mounting.

The Frame Construction Station handles the artwork in batches. The batch size is set to be 12 pieces of artworks/batch. A 5-minute setup for each piece of art is required before the batch processing. Then the frames for the whole batch of artworks will be constructed all together, which takes on average 1.5 hours. These 1.5 hours processing time does not change when the batch size changes.


At Mounting, art pieces are matted and placed in a frame. Mounting is largely a manual operation and does not require a set up. The worker at the mounting finishes one piece of artwork in 10 minutes.

Please use the information provided to answer the following 7 questions.

1. Which kind of batching the Frame Construction Station is doing?

A. Sequential Batching B. Simultaneous Batching

2. The stage capacity of Frame Construction is ______ pieces/hour? (Keep one decimal in your answer.)

3. The stage capacity of Mounting is _______ pieces/hour.

4. The bottleneck of the process is ______.

A. Frame Construction B. Mounting

5. If the demand to the process is 5 pieces of artworks/hour, the flow rate is ______ pieces/hour.

6. If the demand to the process is 4 pieces of artwork/hour, the stage utilization of Frame Construction is _______; the stage utilization of Mounting is _______.

A. 66.7%; 80% B. 83.3%; 80% C. 83.3%, 66.7% D. 66.7%, 80%

7. Please indicate which of the following CANNOT improve the process capacity.

A. Increase the batch size at Frame Construction.

B. Add one more worker to Mounting.

C. Reduce the setup time at Frame Construction.

D. None of the above.

Luxury and Speed at Louis Vuitton

This activity is important because agile organizations rely on uniquely flexible, organic structures that can respond quickly to customer and market needs. Managers should be aware of this type of structure, as it is increasingly needed in global markets where the time from manufacturing to stores is faster than ever.

The goal of this activity is to demonstrate your understanding of organizational structure by reading a case and answering questions that follow.

Read the following case about Louis Vuitton and choose the best answer to each question.

Agile production is the application of advanced technology, processes and employee training that allow a company to respond quickly and efficiently to market needs, while maintaining quality.

Louis Vuitton, a private $50 billion company founded in 1854, is a “suborganization” of Louis Vuitton Moët Hennessy (LVMH), a public company. LVMH has a decentralized structure that allows its sub-organizations to operate independently.

Quality is synonymous with Louis Vuitton (LV) luxury leather goods, but certainly not what you think of when hearing “agile production.” However, Louis Vuitton is a leader in luxury goods time-to-market manufacturing, with low production quality defects and work processes that rely on highly skilled workers.

How can it be possible to combine speed, quality, and changing trends? Louis Vuitton credits agile production. With 460 stores in 50 countries in 2018, the newest 2019 manufacturing sites in France have natural light, fewer supervisors and modular workstations. Along with the fast-to-market, high-quality processes, the company reduces waste and meets environmental protection standards.

Hiring highly skilled employees is very important because workers may complete any part of the product. The company states that it hires only 10% of applicants and that they must have “superior skills.” Even then, the new employees take part in six months of training. It’s not just the employees who are highly skilled. The high-tech machines easily switch modes to adapt to the stage of production. The gains are not just in speed but in lower defects and fewer returns.

The parent company LVMH states that its goal is for Louis Vuitton to “strive to master their distribution: in this way, they offer their clientele unique purchasing experiences.”

Question 1: Louis Vuitton would be considered what type of organization?

a. Hierarchical

b. Mechanistic

c. Matrix

d. Multicultural

e. Organic

Question 2: The business environment for Louis Vuitton would be considered ________ and, therefore, needing ________.

a. Stable; low-cost

b. Dynamic; Stability

c. Low-cost; stability

d. Dynamic; Flexibility

e. Stable; Stability

Question 3: A key part of agile work at Louis Vuitton is having employees who are?

a. Not too specialized and can work at different stages of the production process.

b. Able to train other employees in their specialization.

c. From other industries from which they can bring ideas for new products.

d. Able to work in a highly centralized, formalized environment.

e. Highly specialized and experts in one area of production.

Question 4: The Louis Vuitton new manufacturing sites in France are not consolidated into one very large factory, so the smaller size will help?

a. Increase centralization.

b. Decrease organic nature.

c. Increase formalization

d. Lower formalization.

e. Increase span of control.
