Technology Supporting Business Processes

Over the twentieth century, the ability to process information in terms of labor units has improved by a factor in the order of 1 to 5 trillion. This improvement represents a compounded growth rate of between 30 to 35 percent per year for a century. At the turn of the twentieth century, the mechanical calculator offered a modest productivity increase but the number of workers required to maintain the accounts of a medium-sized business still remained very high. Many tasks would take a large investment in equipment and a significant number of accountants’ weeks to process. A hundred years later, the same tasks can be completed by a standard desktop computer in minutes. The challenge for management has transitioned from a simple reduction in labor requirements to leveraging the increased processing power to develop competitive, efficient, and profitable organizations.

With this example in mind, use the assigned readings for this module and respond to the following:

• Explain how information systems influence businesses to be more competitive, efficient, and profitable.
• Provide at least one example for each factor.  

Write your initial response in 300 words. Your response should be thorough and address all components of the discussion question in detail, include citations of all sources, where needed, according to the APA Style, and demonstrate accurate spelling, grammar, and punctuation

800–1,000 words Details: Weekly tasks or assignments (Individual or Group Projects) will be due by Monday and late submissions will be assigned a late penalty in accordance with the late penalty policy found in the syllabus. NOTE: All submission posting times are based on midnight Central Time. Social Behavior and Monkeys American psychologist, Harry Harlow, conducted a famous experiment that demonstrated the importance of caregiving and companionship in the social development of monkeys. For this assignment, watch this video about the Harlow monkey experiment. Next, observe the social behavior of monkeys by watching the monkey exhibit at your local zoo for at least 10 minutes. If you are unable to visit a zoo, you may watch this video of monkeys in a zoo environment. This video is also found in this week’s M.U.S.E. material. While observing the monkeys, put on your “sociologist hat,” and note the interactions and behaviors that you see. Answer the following questions in a paper of 800–1,000 words: How did the monkeys interact with one another? How is the social behavior and social interaction of monkeys similar to the behavior of humans? Why do you think humans need social interaction? What did you learn from conducting field observation research? What do you think of this as a methodology

TOPICS: Economics, Pricing Strategy

SUMMARY: The economics of trash is an important issue for cities with limited space in landfills or the prospect of significant increases in the cost to haul trash to incinerators at other sites. Plymouth, Massachusetts wants to adopt a pay-as-you-throw or PAYT system. The prospect seems unpopular with residents and the selectmen recently voted to hold off overhauling the trash system for another year. The plan involved charging for the bags residents would be required to use to throw their trash out at transfer stations. The town has no room left in its landfill and sends trash twenty miles to an incinerator. There are many objections to the plan. Senior citizens worry they will have to pay more and some think it will penalize large families. The town faces significant increases in the fees it has to pay to have trash hauled off and incinerated so the goal was to try and change the behavior of residents in advance of the higher costs.

CLASSROOM APPLICATION: The economics of garbage provides insights into strategies that can change behavior. People create garbage and cities have to figure out how to dispose of it. A long tradition of trash removal at low cost and with few restrictions has pressured the ecosystem. Cities need to motivate residents to change their trash habits and recycle. The idea is to make it more difficult and expensive to get rid of trash by tossing it in the garbage. Cities make residents buy special bags, tags or cans for their trash but haul away recyclables for little or no cost. PAYT cities find their residents can get creative. The Seattle stomp is used to compact huge amounts of trash into a single can or bag. Other cities find illegally dumped refuse increases when they implement economic systems to make traditional trash collection or disposal more expensive.

QUESTIONS: 
1. How do financial incentives or costs affect behavior? Why use money as either an incentive or cost to motivate change?

2. Give one example of how consumers changed in response to finance incentives or costs. Here is one example, you think of another… The  drop in miles driven once gas prices increased.  Now yours… 

3. In the past, residents of other cities changed their behavior in response to PAYT but not necessarily in ways cities had hoped. Describe what happened and why it was a problem.

4. Why don’t all cities, including the ones in this article, just require recycling of trash and yard waste like the City of Seattle?

Which of the following is consistent with the theory of vitalism? (1 point) All matter contains a vital force. The chemistry of life and nonlife are similar. Living things contain a vital force absent in nonliving things. Life must be sustained through a series of chemical reactions.
