This would be introduced to highlight the correct positioning of the workstations to be used. This would include the correct height and angle of the monitor to reduce eyestrain. Proper positioning of the keyboard, and the correct height and angle of the chair been used. 6 Network Resources Plan I have decided to place all the network resources in the main central office area in the room where the printer will be stationed. This will be a star topology. This will include the File Server, two 24 -port hubs for each half of the office, the patch panel and the UPS Power Supply.
The cabling will be run under the floor to each socket fitted into the floor, which a workstation can be connected to. 7 Supplier Evaluation and Selection The choosing of a supplier is an important decision and one that could in the long run cost more to the business than first anticipated. I will try and highlight different areas of this process, that can affect your decision, and hopefully this will achieve the aims required. 7. 1 Reputation This is an important factor when choosing a supplier. Has the supplier got a good reputation? If possible talk to existing customers and ask their opinion. 7. 2 Quality components Make sure that the supplier is using good quality components and that they are matched well with each other. It might be a good idea at the time to go with the cheapest quote, but if the components used are of inferior quality then they will probably fail much quicker and so will cost the business money in computer down time and the cost of replacing the components. 7. 3 Warranty It is essential that the systems bought come with a good warranty.
Make sure that the supplier offers a good standard warranty. If possible this should at a minimum include onsite repairs and cover parts and labour. Look to see if the supplier offers more comprehensive warranties that give better response time i. e. 24 hours 7 days a week repairs service with possibly a quick onsite response time of 5 hours. This for a business is more essential than the basic warranty, which is usually targeted at the home market. 7. 4 After sales service This is probably the most important factor to consider. Make sure that the company has a good past record of after sales service.
This should include courtesy follow up phone calls to see if every thing is all right, and prompt response to problems that might occur. A company might offer a good warranty on paper but if they don't follow up their promises then the warranty is not worth the paper it is written on. Again the only way to gauge this is to talk to past customers and get their reactions. 8 APPENDIX A Source material for assignment was attained from the following sources. Internet Websites www.
