Information Systems Essay example -- Business, Technology

Introduction The use of information technology or Information System has defined the way business is conducted globally over the past several decades. The internet has led to high rate of globalization; this is of special significance to the various industries (Reponen 2003). Goods and services can now be offered or sold in a large scale and in various part of the globe. The consequence of this is the growth in customer base for many business entities, especially the supermarkets (Reponen 2003). Due to large markets, various business entities have found it more convenient to adopt the use of information system and Information technology to both manage the large customer data and also reach them in the global market (Burgess, 2002). This report centers on the use of Information Technology/Information System in Tesco Supermarket. It begins by giving a brief overview of the supermarket and examines the benefits and challenges faced by the supermarket as it utilizes Information System (Burgess, 2002) . Description of Tesco Supermarket Tesco Supermarket was founded by Jack Cohen; he started by selling groceries in the market of End of East London from1919. The brand of Tesco first appeared in 1924 after Jack Cohen bought a large volume of tea shipment from T.E Stockwell (Blythe 2008). He came up with the name Tesco by picking the first two letters from T.E Stockwell (TE) S from Stockwell; he then combined these letters with the first two letter of his surname (Co) to form Tesco. The fist Tesco Store was opened 1929. This was followed of opening of the first self-service store in 1948 in St Albans. Subsequently, in 1956, the first Tesco Supermarket was opened. Tesco Supermarket has since established numerous subsidiaries all over ... ...formation technology has helped Tesco Supermarket to link up with its subsidiaries spread over a wide geographical area (Nag & Sengupta 2007). The supermarket has also managed to engage in electronic information interchange with its business partners and clients. The Information System has enabled the supermarket to reduce cost of its operations, increase its efficiency and win the trust and loyalty of its customers. Nonetheless, Tesco Supermarket has experienced some challenges with the use of Information Technology. These challenges have been occasioned by, amongst other factors, system failure, the need to train its workforce every time a new technology is introduced. In some cases, these challenges led to reduced profit margin and increased overhead costs. Moreover, during such challenges, the supermarket experiences slowed rate of work (Singh, et al 2005).

Investment Analysis about two companies.-Pratt Ltd and Dana Ltd. Essay

According to a detail investment analysis by assessing performance, efficiency and financial stability between two companies, we may find a company that is suitable for investment. During the period of analysis, accounting ratios are utilized to direct the discussion. However, there are some limitation relates to ratio analysis, which can be addressed further. At last, a company would be recommended by combining discussion of many factors. Introduction Potential shareholder faces two options about whether investing in Pratt Ltd or Dana Ltd. According to detail information from financial statements, we can use accounting ratios to make a better prediction and analysis about potential advantages and drawbacks in investing in one of these companies. Through interpretation of accounting ratios, we can look closely at the financial state of two companies-profitability, efficiency, and financial stability, and then decide which company to invest in. Profitability Profitability relates to companies’ past and future performance, according to Jacklin.et.al(2007), performance is important , not only because it determines investment returns, but also the analysis of performance may provide a good indicator of the risk of bankruptcy. There are a number of ratios that assist in predicting performance. The first one is gross profit margin, which is represented by net sales divided by gross profit. The ratio calculated in Pratt Ltd is 31.2%, while 37% in Dona LTD, which reveals that every dollar sales of returns 0.37$ in Dona is better than 0.31$ in Pratt, after deducting the cost of goods sold. The second ratio is selling expense ratio, which can be represented by sales divided by selling expense. This measures the relative importance of various expenses in the earning of profit by comparing them to the sales for the period. The result is 3.6% in Pratt, compared with 3.9% in Dana, which indicates higher sales revenue involves higher expenses i n Dana than in Pratt. The next one is net profit margin, which measures net sales divided by earnings after interest tax. This reflects final return to shareholders, the result got is 8.9% in Pratt, 10.5% in Dona. Dona achieves a better return for shareholders. The quality of income ratio focus more on cash generated, it is a measure of management’s efficiency. The result got is 43.5% in Pratt, 4.1%in Dana, which indicates that a lower quality of income occurs in Dana, which relates to the level of income in the form of cash flow. The next one is asset turnover ratio, which measures the relationship of sales to total assets. It indicates how effective it is in generating sales from total investment in assets. The result got is 4.86% in Pratt, compared with 4.28% in Dana, which beyond the industry average level. Assuming valuation used the same for each company, the ratio reveals that for every dollar of investment in assets, Pratt produced more sales than Dana. The next ratio is return on assets, which shows earnings from using the total investment in assets results from net profit margin and asset turnover; we can compare firms on their performance in generating profit from their investment in assets. The result is 57.75%% in Dana, which is higher than Pratt’s 56.76%. Both ratios indicate good operating performance, compared with industry average’s 54.39%. However, it is clear that Dana produce more profit than Pratt. Given their low asset turn over rate, Dana has a higher return on sales, because both them are the same type of furniture store. The last ratio to evaluate operating performance is return on equity, which combines the impacts of performance and financial structure. Jackling.et.al(2004) indicates the success or failure of management in using leverage to improve owners’ returns, when compared with ROA. Dana produces 79.87% in ROE, while Pratt brings 78.35%. Both firms experiences better performance than industry average. However, it is wise to chose Dana because more returns can be achieved by the use of leverage. Efficiency Jacking et.al. (2007) indicates that operating efficiency relates to capabilities of firms to manage its assets so that maximum return can be obtained for the lowest level of assets. The first ratio to measure efficiency is inventory turnover. The result got in Pratt is32 days, which is less than 34 in industry average, 36 in Dana. This ratio indicates that Dana takes more time to turn over into sales, compared with Pratt. Inventory levels are higher in relation to sales and may imply poor inventory management in Dana, which results in high inventory holding costs and obsolete stocks that is difficult to sell. However, in Pratt, although it may indicate good management, it also indicates inadequate stock levels, causing lost sales and excessive restocking costs. Therefore, there is no applied standard to justify whether the higher inventory turnover rate, the more efficiency it can achieve. All what we need is a reliable comparable figure, which represents the overall perfect situation. The next ratio is accounts receivable turnover, usually expressed as the average number of days credit customers take to pay their debt to the firm. Generally, a rapid turnover of accounts receivable is desirable, however, it should not be so rapid to require credit terms that deter prospective customers. The maximum allowed normal credit period is 30 days, which is longer than 23 in Pratt, 27 in Dona. Pratt takes fewer days to collect cash perhaps due to lack of credit sales. Besides, it may indicate poor control over accounts receivable in Dana. This may result in some liquidity difficulties and finally, extensive writes-offs of bad debts. The last ratio to measure efficiency is accounts payable turnover, which represent the average number of days the firm takes to pay debts to suppliers of goods and services. Usually, more days firm takes to pay debt, a worse reputation can be established, which may lead to difficulties in gaining finance from suppliers and financiers in the future. The result got is 32 days in Dona, which is longer than 29 in industry average, 25 in Pratt. This indicates Dona’s debt repayment is less efficient than Pratt; perhaps a large amount of leverage finance is used to promote sales. As well as we know, operating performance in Dona is clearly better than Pratt. The financial structure in Dona is complicated, which needs to be reorganized. Inefficiency in Dona may result in discounts for early payment being missed. this would cause larger amount of expenses in Dona. Financial Stability Short-term Jackling.et.al (2007) indicates that short-term solvency can be assessed by liquidity ratios, these ratios reveal whether the entity has managed its liquidity or cash flows accurately, they can also measure the entity’s ability to repay its short-term debts. The first ratio used is current ratio, it indicates that the percentage of debts arising within the next 12 months that can be met by assets expected to be liquidated within the same period. The result got in Dana is 170%, compared with 150% in Pratt. This reveals that Dana has excessive current asset holding, perhaps due to a poor turnover of inventory or accounts receivable. The efficiency achieved in Pratt is better than Dana. However, liabilities are more likely to be repaid within one year in Dana. Another ratio used is quick asset ratio, which excluding the less liquid current assets and the less pressing current liabilities, the result got is 0.64 in Dana and 0.60 in Pratt. Although there is more stable financial structure in Dana, it is not significant if inventory cannot be sold and debtors will not pay. The ideal ratio may depend on how readily inventory and debtors can be converted into cash and how rapidly sales can be converted to a cash flow into the organization. Long-term Jacking et al. (2007) indicates that the main goal of financial management is to balance the maturity structure of assets and liabilities. Debt to assets ratio and debt to equity ratio can be used. Both of the result got in Pratt is 45%.81%, compared with 43%, 76% in Dana. This result indicates that Pratt has higher leverage of the entity, it may result in increase in the cost of finance relating to interest payments and in the risk of bankruptcy. Pratt is less likely to repay all debts because proceeds from liquidation will be insufficient. Moreover, Pratt may be likely to have difficulty borrowing funds or at the least, may accept higher interest charges. The creditors are more likely to take action to appoint an official receiver or liquidate the organization, if it defaults in payment of debenture interest. Another ratio is used, which measures the safety margin of profit over interest payments, is called times interest earned ratio. The result got in Dana is 5.3, which is better than 4.7 in Pratt. It is safer in Dana that interest charges are well covered by EBIT. Limitation Timing problems The analysis is a static one, the ratios produced from the balance sheet show financial position at a point in time. The income summary cannot reveal any trend during the period. The information base The important information is frequently not disclosed, the data that is disclosed lacks detail. The comparison is difficult because of length of time an asset has been held or different valuation policies adopted by entities. End use Ratios use information from the past and they are not good indicators of the future. No evaluation can take place until some standard for evaluation has been established. The use of ratios arises when some ratios appear satisfactory and some appear unsatisfactory. Recommendation Based on my analysis from three areas of profitability, efficiency, financial stability, Dana is more suitable company to be invested in. Operating performance in Dona is clearly better than Dana. Although operating efficiency in Pratt is better than Dana, it reversely reflects that Dana has a more stable financial structure; the credit risk is lower in Dona. There are some limitations for analysis, but for both of two companies, their encountered impact is certain.
