Discussion: Unlike large organizations, small organizations have been less active in integrating information technologies into their business operations. For example, some of the larger airliners use online information technologies to allow passengers to make reservation, buy a ticket, reserve a seat, check in, and even print their boarding passes online before they get to the airport.

• Using the airlines example mentioned above, propose several possible IT solutions and how they would benefit a smaller airline to become more successful or attract more clients.
• Tell us if the availability of information technology services has influenced your decision to travel on a particular airline. What airline was it?Discussion: Unlike large organizations, small organizations have been less active in integrating information technologies into their business operations.

Symbols of culture are called artifacts. Artifacts are the most visible and accessible level of culture. These include behaviors, stories, rituals (everyday practices that are repeated frequently), and symbols (e.g., company logos, company colors). For example, the president of a company volunteering at Habitat for Humanity is an artifact of culture. An example of symbols as an artifact of culture is Ashford University’s shield that serves as our logo and is printed on transcripts, diplomas and letterhead paper. Submit a two- to three-page paper (excluding the title and reference pages) describing the culture of either your current or past place of employment. Your paper should provide examples of and address each of the following topics: 1.Observable artifacts 2.Espoused values (These are what organizational members say they value, like ethical practice.) 3.Enacted values (These are reflected in the way individuals actually behave.)

In addition, describe how each item listed above impacts the values and culture of the organization.

Your paper must use a minimum of two scholarly sources, in addition to the textbook. Your paper must also follow the APA Style guide.

Strategic Behavior Oligopolies

 

An interesting example of strategic behavior comes from a 1997 article about Microsoft’s investment in Apple (New Straits Times, 1997). The article is included in the Required Readings list. Facing tough anti-trust scrutiny from government agencies, Microsoft provided financial support to Apple in order to ensure Apple’s survival and, therefore, to ensure that competitiveness in the industry remains. Moreover, the partnership with Apple provided an additional market for Microsoft’s products – the MS Office and the IE products were to be bundled with the MAC OS as one of the conditions for this financing. Discuss this case in the context of market structure and strategic behavior. What market structure do these firms operate in? Why did Microsoft need to preserve competitiveness in the industry? What was Microsoft afraid of in the event that Apple did not survive?

Guided Response:

In 300 words or more, please, provide your response to the above discussion question. Further, do you think Microsoft regrets taking action in light of Apple’s performance today?

 

Local Market Power

 

Bulls Eye department store specializes in the sales of discounted clothing, shoes, household items, etc. similar to the offerings at a regular Walmart or Target. Bulls Eye is the only department store in Show Low and the nearest other discount retailer is Target, located 49 miles away in Eagar. Bulls Eye, therefore, has some market power in its local area. Despite having some market power, Bulls Eye is currently suffering losses. An analyst at Bulls Eye is recommending to the manager to raise prices, so that profitability can be improved. The manager is unsure of this strategy as recent data points to increasing numbers of individuals shopping more and more. What are the pros and cons of raising the prices at Bulls Eye and would that strategy be profitable?

Guided Response:

Consider demand elasticity and market structure in your response. How is increasing of the price going to impact the company’s revenues given its demand elasticity? In 300 words or more, please, provide your response to the above discussion questions.
