Introduction

2B - An ICT System Introduction In unit 2B I am going to be looking at Tesco. I will be focusing on what they're like as a company, the corporation's aims for the future, and how ICT is necessary for Tesco to achieve maximum productivity. Tesco's purpose is to effectively provide a range of groceries to customers. Some of Tesco's main aims are to: * Be energetic, innovative and be first for customers, * Use their strengths to deliver unbeatable value to customers, and customer satisfaction * Strive to do their very best, * Achieve staff satisfaction * Enjoy work, celebrate success and learn from experience, * Appeal to a diverse customer base through providing a range of products, bringing value and offering a range of store formats, * Be easily accessible for the disabled, * Develop store structures to better meet the needs of both customers and staff. * Uphold high standards of animal welfare, * Promote recycling and sustainability, and, * Expand internationally. Tesco are an international, UK based retail chain. It is the largest British retail company, and started out specializing in foods, but has branched out into many more areas such as clothing, cosmetics, DVDs, music, electronics etc. What makes Tesco different is the fact that they strive towards various goals, from things like customer services to being environmentally aware; these sorts of priorities distinguish Tesco from competitors like Asda and Sainsbury's. Tesco are very reliant on ICT using obvious things like cash registers and also less obvious things like the stock market. Tesco is now in charge of more than 30% of the grocery market in the UK. They also provide an online shopping service. They are even involved in the 'Computers for Schools' initiative, making the public aware of their stance towards the future development of Information Technology. They also use EPOS, which is what I will be looking at. ...read more.

Tesco's hard drive is used to store essential information on each till PC and the information from the till, like the transactions that have taken place. The hard drive is linked to most of the rest of the system because other aspects of EPOS are saved onto the hard drive. It is, for example, linked to the laser scanner, because the laser scanner enters product information, which is later saved by the hard drive. The strengths of hard drives are that they have a big memory and can store lots of data, and they are secure. These are both important qualities for Tesco. They are also better value than buying many storage devices that would hold the same amount of information as a hard drive would, for instance lots of memory sticks. Weaknesses are the price of hard drives, they do cost a lot of money, even if they hold lots of data, particularly if it is a hard drive with a large memory that is required. This would have a negative effect on Tesco because that means less money for them to spend on other aspects of the company. Hard drives are also not particularly versatile in that they are not removable, so you cannot use them wherever, which is not particularly convenient. An alternative would be a USB stick, or another type of storage device. These are better in a way because they can me moved around, and are quite a lot cheaper. But Tesco would get less for their money if they went down this route, as memory stick memories are not as large as hard drive ones. That is why Tesco do not use this alternative. This meets the aim of staff satisfaction, because the information necessary for employees to do their job is saved securely. Backup (Magnetic Tape) When Tesco need to back up data they have collected during the day, they use magnetic tape. ...read more.

Conclusion

This would be even more vulnerable to human error than EPOS Software is, and would be very inefficient and time consuming. Tesco don't use the alternative for these reasons. This meets the aim of staff satisfaction, as they have an easier job if they can access all the information they need to in one place on the computer. It also means customers waiting time is as short as possible, which contributes to staff satisfaction. Evaluation The components that I have covered together make an ICT system. The system software tells everything what to do. The hard drive stores programmes needed to run the system properly, and all the other data needed, for instance the stock control database. That contains all the products and their details. Some data is backed up, on magnetic tape, and sends information to the receipt printer and LED display, which can show customers details of the products they are buying. This all helps achieve customer satisfaction, as they can view the products they have bought as they are being scanned, and have a hard copy to take home with them. Information can be inputted using the touch screen, and products are scanned using the laser scanner, which scans barcodes. This meets staff satisfaction, another aim, because the speed and simplicity of this process makes their jobs easier. All the computers are connected in a network using an RJ45 cable, which helps information to be computed and communicated to other computers and shops, and generally allows Tesco to function properly, and hopefully meet all their aims in the process. These all contribute to a successful transaction in Tesco. The EPOS system helps Tesco to provide staff and customer satisfaction, and be as environmentally friendly as currently possible. It is designed to result in minimum waiting times, and pleased staff and customers. Tesco can now continue to expand their international company with a successful computer system and positive aims for the future. ...read more.
