• Case Study Scenario

Exotic Cars Inc. (ECI) is a company specializing in sales and maintenance of the exotic
cars. The cars that ECI sells come from multiple sources
• Shipped directly from factories
• Purchased from private collectors
• Traded-in by customers of ECI

ECI also provides a regular maintenance service of the exotic cars, such as engine
tune-up, tire rotation, oil change, etc. You do not have to buy a car from ECI to use its
maintenance service; consequently, some owners of the exotic cars purchased
elsewhere also use ECI maintenance service.

ECI appreciates the continued business of its patrons. Consequently, the company
wants to maintain as much information about each valued customer as possible.
As a result, ECI diligently records how much money each customer spends on buying
cars (more than half have purchased two cars and about third bought three or more), on
maintenance service (how much customer spends overall, and per car), and whether or
not a customer ever traded a car in.

Similarly, ECI maintains detailed data on all the dealers, companies, manufacturers,
and other sources that provide the company with needed services, parts, or cars.
ECI is not a “backward” organization, but things have been done there pretty much the
same way since ECI was founded in 1966. The owners of ECI feel like it is about time
not just to move forward, but “leapfrog” the competition.

You, along with the members of your team, have been hired by ECI to find a way of
dramatically increasing the level of performance of ECI.

• Organizational structure of ECI

There are three operational locations of ECI
• Washington, DC,
• Richmond, VA,
• Virginia Beach, VA.

The corporate headquarters are located in Charlottesville, VA. Every location has a
general manager who is responsible for authorizing/rejecting requests area managers
may have. Normally, area managers only handle the issue relevant to their area. For
example, sales/trade-in area has its own manager, body shop/repair shop has its own,
and service area has its own area manager. Every area manager is authorized to make
financial decisions up to $10,000.00. If the amount exceeds the limit of an area
manager, then the general manager of that location must authorize it–the general
manager has discretion of making financial decisions of up to $100,000.00.

If the amount exceeds this number, a request is send to the headquarters, where it is
approved or rejected by the VP of the area (e.g., service, sales, and repair). The VP of
the area is authorized to make financial decisions of up to $250,000.00. If the request
exceeds this amount, it must be addressed by the CEO of ECI.

Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.
