Throughout this time, the business has focused on selling a wide range of cars. Throughout the ten years of the business, the methods employed on the calculation and sale of cars has remained more or less the same, the calculation of costs being done in a paper-based system, probably due to the relatively small size of the business. Using the paper based system was rather a slow and inefficient method; a customer order form was hand written and photocopied as appropriate and was filled in for each customer, however, when the business changed its car range or added to its range, the order form had to be re written by hand and photocopied again, proving to be quite a tedious task. Another implication of this was that less options of the car could be customised and only basic options could be configured to the customers demand. There was also a slight other problem, customers who telephoned the business had to give their details over the phone all over again each time they phoned and these details were held in traditional filing cabinets. ...read more.

The fact that a USB port was readily available, plus a Hard Drive and a floppy disk drive meant I was spoilt for choice to save and backup my work to and disk space didn't prove to be an issue except on a floppy disk where the system was too large to hold on a single floppy disk. It also meant my work in implementing the system was portable, as I could take it home and work from home, when Mr. Cruiser packed up for the day. * The software that was used was used varied on the operating system, because Windows XP was available for use, plus Mr. Cruiser had Windows ME available, however, the differences between these two operating systems didn't affect the way I worked if only the menus etc. seemed a little different, XP being more up to date having endless features probably not required to implement my system. The differences between XP and ME were mainly only a facelift from ME, nothing to affect the way my system would work, therefore, it seems my system would be compatible on a range of operating systems from Windows 95 through to Windows XP Progression, Evidence and Annotation of the Implementation Process Here I will show the implementation process from scratch, right from the first start of building the system, through to the final few stages where the system reaches completion, worksheet by worksheet. After a while however, there came a change in the designs and implementation of the system. Mr. Cruiser set the deadline and time was at a shortage. I realised that there would not be enough time available to create a page for each of the 10 manufacturers available to choose from. Mr. Cruiser suggested that the system be seen as a trial of what the system could achieve and also advised that fewer manufacturers be available to choose from for the moment. ...read more.

Conclusion

On several cases during the implementation, when it came to saving, the system would often stop responding and sometimes, data was lost as a result of this. Saving the system proved be more slow and sluggish as the system was added to, therefore in future it would be advisable to attempt to keep the size of the system small, by removing any unnecessary objects, such as a background, which wouldn't affect the functionality of the system. Performance The system performs relatively well and is easy to use, as I provided a questionnaire for users of the system and received a wide range of comments; some suggested improvements and some also commented that the system was easy to use and functional. This questionnaire and the results of the questionnaire are available to view later in this documentation. The system wasn't generally slow to run, however, updating the system and then saving it did prove some issues as explained under the previous heading Is the system reliable? Maintenance and updating To be quite honest, the system would be rather tedious to update as it involve much time to carefully update and replace each part of the system, however, in many ways it is easy to update because for example, due to the wide use of list boxes and combo boxes, these wouldn't have to be replaced, more so they would have to be reformatted to account for additions to the system. As the system was created as a trial and as Mr. Cruiser suggested, the system should have been designed so that updates and additions to the range and price lists could be made. As a result, all data that referenced to cell links etc was stored on a single hidden page (format>sheet>hide/unhide as necessary) therefore with all data stored on a single page, items can be added or removed as required for example from the car range, also prices can be changed and these will be automatically updated where necessary. ...read more.
