1. Outsourcing means a company runs a computer application which is developed by the other institutions and it contains a range of work schedules. The aim of implementing outsourcing is to overcome operating troubles happened in the information unit and to help those companies that do not need to manage a information system to gain a more effective computing. The benefits of outsourcing are that it enables companies not only gain efficient systems but save cost. 2. The origin of software is mainly comes from six sources: the information technology services, which helps companies to develop custom information systems for internal use, packaged software producers, which are those exclusively manufacturing major software on the market, enterprise solution software, a system to make individual conventional business functions to be various modules, clouding computing, which allows customers to invest in order to use resource of the third-party by internet or VPNs, open source software, a free product offer by a community of interested people , and in-house development , which means the company combine some in-house software and some purchased application. If the company neither has expertise or employees to develop system in-house nor off-the shelf system is available, information technology services firms are its first option. On the other hand, when the company needs generic application, it can turn to packaged software producers. And if the company is short of completing the separate functional boundaries, it can choose enterprise solution vendors. While the corporation both has capital and ordinary need for system, cloud computing is a good choose. If the enterprise has generic demand in system but lack of enough money, open-source works better. If the company has its own employees to develop the system, then they choose to apply in-house development. 3.

Problem Of Evil Argument Analysis

...The problem of Evil is an argument that seeks to disprove God’s existence. In this paper, I will iterate and elaborate on the problem of Evil and deliver critical points that question the soundness and the strength of the argument so as to assess the argument from a critique’s standpoint. The problem of evil is based on the personalities of God, such that God is omnipotent, omnibenevolent and omniscient. So, if such a perfect being with all the personalities were to exist, there would be no evil. However, evil does exist. Hence, God does not (sober, 119). The argument takes the logical form, if X then Not-Y. Y, hence not-X. In my opinion, this form is not prone to any counter-example, nor does it beg the question, suggesting that it is deductively...

Business Systems Analysis Problems and Exercises

...Problems and Exercise 1. Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way seems to be “quick and easy?” What value is provided by using an “engineering” approach? It is a good idea to use a system analysis and design methodologies when building a system because it creates a system that creates solutions for the entire business unit, instead of wasting resources patching the issues as they come. 8. How might prototyping be used as part of the SDLC? Prototyping can be used within the SDLC methodology by falling into the testing phase of the system. Since prototyping is creating a version of the software, it could be used to test for bugs, and make upgrades as necessary. 3. Suppose the choice is between alternative custom software developers rather than prewritten packages. What criteria would be appropriate to select and compare among competing bidders for custom development of an application? Define each of these criteria. • Cost – Comparing the cost of developing the same system in-house to cost of purchasing. • Functionality – if the software will meet the function requirements. • Vendor Support – Refers to whether the vendor can provide support, and how much. • Viability of Vendor – How reputable the vendor is, and how long they will continue to be in business. • Flexibility – Refers to how easy it is for you or vendor to customize the package • Documentation – Includes...

...Before proceeding in problem determination, there are some initial questions to be answered. Have you changed anything recently? If you have changed, added, or removed software or hardware just before the problem occurred, back out the change and see if the problem persists. What else is running on the workstation? If you have other software, including a firewall, try switching it off to see if the problem persists. Is the problem reproducible on the same workstation? Knowing that this defect occurs every time the described steps are taken is helpful because it indicates a straightforward programming error. If the problem occurs at alternate times, or occasionally, thread interaction and timing problems in general are much more likely. Is the...

Jamie Turner : Case Analysis - 4 Problems

...where departments such as control, budgeting, planning and similar tasks were well supported. When he was allowed autonomy and was all on his own, he could not get enough time to prepare himself for all the challenges that were posed for his position and he ended making hasty decisions based on his prior experience. Secondly, his differences with Cardullo regarding their views on the cash flow problem, pricing halogen bulbs below the break-even point with reduced margins, and their other arguments left Turner in distaste and anger. Turner’s strategy of reducing production cost and lesser margins did not go well with Cardullo who wanted higher margins for his products. Moreover, Turner was initially indecisive about joining MLI given the financial situation of the company and other complexities that a merger had created. Also, he was not really keen to go into industrial marketing. He did not weigh the positives and negatives completely before accepting the offer at MLI and started repenting his decision after just a few months into the company. All these things along with the problem of dealing with Julie Chin, lead to this particular predicament. 2.  What did Pat Cardullo and Jamie Turner each initially bring to the situation at MLI that should seem to ensure success? Failure? Solution: Jamie Turner initially met a lot of people, learnt about the business and tried settling into his new responsibilities. This was essential given the huge responsibility he had taken up....

By that year, I expect people to completely redesign the hardware and interface of cellphones. I see the physical devices being reduced to projection instruments placed in certain devices, like a wristband, that projects the user interface onto the subjects arm. The user could the control the device with voice commands or physically touching the area the image is displayed. This would allow devices to be used while swimming or any situation that involves water. I also see them beginning to tweak the software that Stephen Hawking uses to control his computer, and implementing it into cellular devices. This would allow people with physical disabilities to use and operate a cell phone by subtle gestures of the face, eyes, and neck.

The Analysis of Training Needs Must Go Beyond What Seems to Be the Problem

...by evaluating the problem or the need which may be present or likely to arise as well as the solutions. Drummond (2008) states that the need analysis can be sometimes called Training needs analysis which is defined as the process of identifying the gap in employee training and related training needs. This script therefore aims at bringing out whether the training needs analysis and training itself being the solution must have a wider scope and leap beyond what seems to be the dilemma or must be narrow scoped and focus on the problems at hand in the organisation. Pfeffer (1998a) states the basis of training being to provide skilled and motivated workforce and he clarifies it under what he called ‘best practices’. This clearly shows that the process of training goes beyond just educating the worker or rather intellectual emancipation but it also motivates the workers in and after the process for instance if workers are sent for training because they are lacking computing skills, they not only benefit the knowledge on computers but also get motivated as they feel that the organisation is putting them into consideration by investing knowledge in them and is prioritising their intellectual wellbeing so this shows that the process of training goes beyond what may seem to be the problem but also goes an extra mile in motivating them too. Beardwell and Holden (2001) state that the focus of the analysis of training needs must not be on tackling the current problem but must be based...

...____ Date: May 31st, 2016 Subject: Problem Analysis The issue in which I would like to raise incorporates the State of Michigan, and their lack of policy and contribution in the reconstruction of public roads. Accidents have increased and public road conditions continue to grow worse. For the fact that I live in Michigan, I am concerned about the amount of roads that go un-fixed for long periods of time. Public roads play a major role in not only transportation of individuals, but also the transportation of goods and services as well. The lack of upkeep on public roads can cause issues throughout the state1. These issues could come with numerous, dangerous side effects. If we experience a lack of upkeep on the public roads, individuals may have to find other means of transportation to and from work causing a hardship to contribute for society and his/her household. Less people are choosing to live near places that aren't providing the proper upkeep on their roads. This is causing some communities2 to become overpopulated, while other communities are experiencing a depletion in their populations. This is a major issue to pursue, but it can only be fixed when it is tackled head on. The solution to the problem is to generate money in order to pay for the upkeep and reconstruction costs of public roads to help keep the communities of Michigan safe. 1 This report will only cover the State of Michigan. The problems, analysis, and suggested solutions may, or may ...

This is one of the reasons why the United States (US) prisons are the highest populated in the world (Vicini, 2006). According to statistics, the US shows that in 2006 seven million people were in prison or on probation or parole. Of this amount, over two million were physically in jail or prison (Vicini, 2006). According to Ethan Nadelmann the US has five percent of the world’s population, and also has 25 percent of the world’s incarcerated population (Vicini, 2006). The United States also imprisons more people on drug charges than all of Western Europe combined (Vicini, 2006). Like every other county jail, DuPage County jail is overcrowded due to the backlog of the court dockets. Alleged offenders must wait for their day in court and then be sentenced and transported to various prisons. Many of these offenders are non violent offenders, or are first time drug offenders (Vicini, 2006). In Cook County jail many inmates are tried and sentenced, but depending on the crime the sentencing could be one year or less in the county jail, prison time, probation, periodic imprisonment, or conditional discharge. There is however, another choice for first time drug offenders and non-violent offenders and that is Boot Camp. Boot Camp Boot Camp is...

Problem Analysis

...Problem Analysis In a typical organization, several problems arise; most of these come from different situations. Three of the broad categories that give rise to this situation are the policies, procedures and people. Among the accounts associated with these are the cash, accounts receivable and the inventory. Cash for example is a highly liquid asset which also has a high inherent risk. Certain circumstance pose to cash count that does not match or tally with the recorded cash and cash receipts. These usually happen because of an insufficient policy regarding cash transactions. Several organization also bypass the need for segregation of duties, because of these the account balances in return, are compromised. Authorization, custody and recording usually lies with just one person giving rise to situations that magnify risk. There are also organizations with decentralized handling of cash wherein several people has custody over it, this gives rise to confusion as to what really is the cash balance, and sometimes the people handling cash is unaware of how much they actually have on hand, because of this the reliability of cash count may no longer be depended upon given the fact that the people handling it may also give unreliable responses as to how much they have. Unqualified person sometimes are given the authority and custody over cash. Unqualified person may include but is not limited to persons who lack integrity and those who do not have the commitment to perform...

...1. Executive Summary The primary goal for the Brita products company is to obtain faucet mounted products’ retail market share by at least 10 % in 2 years as a niche product targeting younger people aged between 18 and 44 in western U.S. while maintaining the market share of pitcher products. The main impediment for this is that PUR, number 2 brand, already has owned 74% of total faucet mounts sales in market. The solution for this can be divided into 2. One is to launch innovated faucet-mounted products to earn the market, highly preoccupied with PUR and the other one is to redirect the market towards younger people for Brita pitchers. 2.

Then, write a short paragraph describing the results. Be sure to discuss any unique issues related to data such as outliers, large variance, and so forth. What happens to each running back's results when you eliminate their longest run of the day?

Running back B’s results have a greater spread or dispersion of the data, therefore has the larger variance and standard deviation. Running back C has a greater concentration of the data around the central value, therefore resulting in minimal variation as seen with the smaller variance and standard deviation for Running back C’s data set.

...oral analysis. 1. Be complete. Each area of the situation analysis must be discussed, problems and opportunities identified, alternative presented and evaluated using the situation analysis and relevant financial analysis, and a decision must be made. An analysis that omits part of the situation analysis or only recognizes one alternative is not a good analysis. Second, each area must be covered in-depth and within insight. 2. Avoid rehashing case facts. Every case has a lot of factual information. A good analysis uses facts that are relevant to the situation at hand to make summary points of analysis. A poor analysis just restates or rehashes theses facts without making relevant summary comments. 3. Make reasonable assumptions. Every case is incomplete in terms of some piece of information that you would like to have. A good case analysis must make realistic assumptions to fill in the gaps of information in the case. For example, the case may not describe the purchase decision process for the product of interest. A poor analysis would either omit mentioning this or just state that no information is available. A good analysis would attempt to present this purchase decision process by classifying the product and drawing upon real life experience. Could you not describe the purchase decision process for a bike, even though you have never read a research report about it? 4. Don’t confuse symptoms with problems.
