What organization design aspects of Zara make it so succuccessful ?
Answers
Answer:
The secret to Zara’s success has largely being driven by its ability to keep up with rapidly changing fashion trends and showcase it in its collections with very little delay. From the very beginning, Zara found a significant gap in the market that few clothing brands had effectively addressed. This was to keep pace with latest fashion trends, but offer clothing collections that are a combination of high quality and yet, are affordable. The brand keeps a close watch on how fashion is changing and evolving every day across the world. Based on latest styles and trends, it creates new designs and puts them into stores in a week or two. In stark comparison, most other fashion brands would take close to six months to get new designs and collections into the market.
It is through this strategic ability of introducing new collections based on latest trends in a rapid manner that enabled Zara to beat other competitors. It quickly became the people’s favourite brand, especially with those who want to keep up with fashion trends. Founder Amancio Ortega is famously known for his views on clothes as a perishable commodity. According to him, people should love to use and wear clothes for a short while and then they should throw them away, just like yogurt, bread or fish, rather than store them in cupboards.
The media often quotes that the brand produces “freshly baked clothes”, which survive fashion trends for less than a month or two. Zara concentrates on three areas to effectively “bake” its fresh fashions:
Shorter lead times (and more fashionable clothes): Shorter lead times allow Zara to ensure that its stores stock clothes that customers want at that time (e.g. specific spring/ summer or autumn/ winter collections, recent trend that is catching up, sudden popularity of an item worn by a celebrity/ socialite/ actor/ actress, latest collection of a top designer etc.). While many retailers try to forecast what customers might buy months in the future, Zara moves in step with its customers and offers them what they want to buy at a given point in time.
Lower quantities (through scarce supply): By reducing the quantity manufactured for a particular style, Zara not only reduces its exposure to any single product but also creates artificial scarcity. Similar to the principle that applies to all fashion items (and more specifically luxury), the lesser the availability, the more desirable an object becomes. Another benefit of producing lower quantities is that if a style does not generate traction and suffers from poor sales, there is not a high volume to be disposed of. Zara only has two time-bound sales a year rather than constant markdowns, and it discounts a very small proportion of its products, approximately half compared to its competitors, which is a very impressive feat.
More styles: Rather than producing more quantities per style, Zara produces more styles, roughly 12,000 a year. Even if a style sells out very quickly, there are new styles waiting to take up the space. This means more choices and higher chance of getting it right with the consumer.
Zara only allows its designs to remain on the shop floor for three to four weeks. This practice pushes consumers to keep visiting the brand’s stores because if they were just a week late, all the clothes of a particular style or trend would be gone and replaced with a new trend. At the same time, this constant refreshing of the lines and styles carried by its stores also entices customers to visit its shops more frequently.
In the following sections, the key components of Zara’s winning formula in the fashion retailing industry are illustrated.

You are considering purchasing an office building for $2,500,000. You expect the potential gross income (PGI) in the first year to be $450,000; vacancy and collection losses to be 9 percent of PGI; and operating expenses and capital expenditures to be 38 percent and 4 percent, respectively, of effective gross income (EGI). What is the implied first-year overall capitalization rate
Answers
Based on the information given the implied first-year overall capitalization rate is 9.50%.
Vacancy and collection losses = 9% of PGI
Vacancy and collection losses =$450,000×9% Vacancy and collection losses=$40,500
Effective gross income (EGI)= PGI - vacancy and collection losses
Effective gross income (EGI)= 450,000 - 40,500
Effective gross income (EGI)=$409,500
Operating expenses= 38% of EGI
Operating expenses= 0.38 × 409,500
Operating expenses=$155,610
Net operating Income(NOI)= EGI - Operating expenses
Net operating Income(NOI)=$409,500 - $155,610
Net operating Income(NOI)= $253,890
Capital expenditure= 4% of EGI
Capital expenditure= 409,500×4%
Capital expenditure= $16,380
Adjusted Net Operating Income=Net operating Income - Capital expenditure
Adjusted Net Operating Income=$253,890 - $16,380
Adjusted Net Operating Income=$237,510
Implied overall capitalization rate = Adjusted Net operating income ÷ Value of property
Implied overall capitalization rate=$237,510 ÷$2,500,000
Implied overall capitalization rate=9.50%
Inconclusion the implied first-year overall capitalization rate is 9.50%.

Harper Motors sells 32 cars per month at an average price of $24,360. The carrying cost per car is $144 and the fixed order cost is $687. How many orders should the company place per year
Answers
The number of orders that the company should place per year is 6.34 orders.
Economic order quantity (EOQ) = (2* yearly demand*per order fixed cost/carrying cost per unit)^(1/2)
Economic order quantity (EOQ) = (2*(32*12)*687/144)^(1/2)
Economic order quantity (EOQ) = (2*384*4.7708)^(1/2)
Economic order quantity (EOQ) = 60.530772339
Economic order quantity (EOQ) = 60.53
Number of orders to be placed = Yearly demand / EOQ
Number of orders to be placed = (32*12)/60.53
Number of orders to be placed = 6.3439616719
Number of orders to be placed = 6.34 orders.
Therefore, the number of orders that the company should place per year is 6.34 orders.

Olivas Recreation reported a net income of $3.2 billion, interest expense of $214 million, and income tax expense of $195 million in 2022. What is their times interest earned
Answers
The times interest earned is 16.86 times.
The times interest earned is also known as interest coverage. It is a type of coverage ratios. Coverage ratios measure the ability of a company to cover its debt payment.
Times interest earned = earnings before interest and taxes / interest payment
Earnings before interest and taxes = net income + interest expense + tax expense

Times interest earned = $3.609 billion / $214 million = 16.86 times

Alpha and Beta Companies can borrow for a five-year term at the following rates: Alpha Beta Moody’s credit rating Aa Baa Fixed-rate borrowing cost 10.5% 12.0% Floating-rate borrowing cost LIBOR LIBOR + 1% This time assuming more realistically that a swap bank is involved as an intermediary. Assume the swap bank is quoting five-year dollar interest rate swaps at 10.7% - 10.8% against LIBOR flat. Consequently, Alpha will issue fixed-rate debt at 10.5% and Beta will issue floating rate-debt at LIBOR + 1%. Alpha will receive 10.7% from the swap bank and pay it LIBOR. Beta will pay 10.8% to the swap bank and receive from it LIBOR. If this is done, Alpha’s floating-rate all-in-cost is: 10.5% + LIBOR - 10.7% = LIBOR - .20%, a .20% savings over issuing floating-rate debt on its own. Beta’s fixed-rate all-in-cost is: LIBOR+ 1% + 10.8% - LIBOR = 11.8%, a .20% savings over issuing fixed-rate debt. Is that analysis correct?
Answers
Based on the information given about the LIBOR, it can be deduced that the analysis is correct. Therefore, it's true.
From the information given, the quality spread differential will be calculated thus:
= Differential fixed rate debt - Differential floating rate debt
= (12.0% - 10.5% - 1%)
= 0.5%
In this case, a positive quality spread differential implies that the swap is in favor of both parties.

Many have tried to duplicate the recipe unsuccessfully, and burglars have even been caught trying to steal it. One day Martin is called into the president's office for an assignment, and during their conversation, the president leaves the room, leaving Martin alone. Martin notices that the wall safe is open and looks inside, where he sees an envelope labeled "THE RECIPE."
