Introduction

Coursework Documentation file Appendix 2 Name: Rhianna Ingram Form: 11Y Teacher: Mr Langan Final Mark: (AO1-1) Choosing and Describing Applications 5 To create my application I used a range of different hardware and software programs. I used a micro desktop computer, VDE / CRT Monitor, a standard keyboard and a mouse as my hardware components. For software I built my application in Excel, I used paint to edit the image I have included in my application. I have also used Microsoft Word for the Mail Merge component of my application. There are many other types of software I could have used. I could have used another program to create my application, such as Database or another Spreadsheet software, like Microsoft Works Spreadsheet / Database. By using these I would still have the function of entering formulas and process', but there aren't as many features on either of these software's compared to Excel. As the image I have placed into my application is not a photo and all I wanted to do was paint on top of the image I used paint. Although if I wanted to edit the image or distort it there are many different software's that all hold different features, Imaging, Photo Suite, Kodak Photos editor. I think that I choose the most effective pieces of software; Microsoft Excel gives me more options to create a more aesthetically pleasing product. I can create Macros that save time and are an asset to my program as they are useful and easy for the user to use. I used Microsoft Words to create my letters as it has the Mail Merge feature, which means I can create multiple letters, that contain the same information but the address and name is different on each one. The information for the address' etc is taken from an already existing database. If I didn't have to use of ICT, and had to create a similar system there are other way of filing the information. ...read more.

These are the only possible options that are available to my application at the moment, but if I were to implement my application it into a shop then I would fit a barcode scanner in. This is a scanner that scan the barcode on the products, if I used this I would then have to attach a barcode to all my products, or have a book with barcodes and description of the products at the till. It would be more time affective if there were a barcode attached to each individual product. Using a barcode scanner it is a lot more accurate than typing in the data. Although I have included a short description of each piece of merchandise, which appears when the item is scanned in, but if this information is overlooked by the employee then the customer could be over of undercharged, and this could also affect my stock taking levels. So I would advise that a scanner were used and the levels of accuracy are much more affective. AO1-5 System Output 5 The final program will be accessed by a computer within the shop / concession, it will most likely be a standard micro desktop computer, with keyboard, mouse and VDE / CRT monitor, or something with similar capabilities. There are various output methods that I need to include, firstly there is the screen to think about, I would use a VDE / CRT monitor for the shop employee to use and then a another screen for the customer to look at, to check the prices, I would use a matrix screen, which displays the price of each item as it is scanned, the total price, the amount of cash handed over and the change. I would also have to install a printer so that a receipt could print out. As my receipt is a built in function to my EPOS system it has been set to print out as A4 - the standard size for an inkjet / laser printer. ...read more.

Conclusion

I think that the guide would be better if it was more detailed, giving slightly longer descriptions." Having this feedback has given me the chance to work on my user guide to try and improve it. I am going to create a more detailed guide giving better explanations on each process. I also want to try and include some information on how to enter new data or change existing data. As the stock check and customer database is variable information I think that it is important that the end user has some idea of how to change this. I have now attached my new user guide with the amendments, and this is what my previous testers thought about it. "I think that this is a brilliant improvement, it gives more details and explains how to change things that someone could easily have to change."- Mrs G Haler Mr S Jones - "This guide is better now as it gives more adequate details on the different process and is laid out in a much better manner, it is easy to understand and makes to system easier to use." Benefits and use of ICT (AO3) 5 My system will benefit users, as it is a quick and effective system that processes information quickly eliminating many of the old manual processes. Using the EPOS system, it means that my staff can quickly serve customers using accurate equipment that is fast, as the computer calculates all the sums and using VLOOKUP formulas all of the information is brought together, without looking for it separately. By creating a macro that copies and pastes the information to create a receipt, therefore by simply clicking on one button the whole process is complete. That's why it is so effective as it is fast and accurate - there is no way in that the user could create an error. There are many benefits for the company, such as it is accurate, it is fast, and there is less need for so many staff on the shop floor. ...read more.
