Solution to the problem

Mr. David has decided that the pizza delivery will get a computer right by the phone so that the member of staff who picks up the phone can type in the information and add up the prices and take off the discounts on computer and this will be neater so the people can read it and it will be more accurate so they will charge the right price to customer and deliver the pizzas to the right people.

Objectives / User Requirements

• the spreadsheet should be neat and easy to use
• the system should automatically add up the sum of the money for the pizzas
• the system should print out the invoice within  10 seconds
• the price automatically appear with the name of the pizza
• the sheets should be protected to avoid anyone accidentally deleting any information or formulas
• the system should have a sheet that looks good and contains the company logo, and stores information of the available pizzas and their prices and another one to do all the working out of the prices and taking off of discounts and any other adding up that needs to be done

System

Mr. David will need a system which has minimum requirements. The system should be quick and easy to use so that the user doesn’t have to think that much when entering the details. The system should be able to calculate prices and work out discounts of the people who ordered the pizzas. He should have a computer that runs Windows XP, a black and white printer, a mouse and keyboard and it would be nice if he could get a touch screen but that is just too expensive. I will do the data base on excel and not on Lotus 123, this is because I have more knowledge of excel than I do of Lotus 123.

Collecting Data

The data that was collected was carefully calculated and considered by my own judgement and experience in pizza and drink pricing. There will be a menu of all the varieties of things available in stock and the code number of the item will be displayed on the page next to the item.

• Price of drink
• Variety of drinks
• Code number of drinks
• Size of pizza
• Price of pizza
• Flavour of pizza
• Code number of pizza

And all the rest of the data like the sum of the total amount and the discount that was calculated were all done on the spreadsheet and calculated by the spreadsheet.

Processing the data

The user enters what food or drinks are being sold into the spreadsheet using v-lookup. The spreadsheet then totals the different food and drink up. The user is given an option to give a 10% discount if the price is over a certain limit, so I will use an If statement, in conjunction with a formula that will work this out.

Conceptualise          

Mr. David thinks the spreadsheet should have a maximum of three pages, and I thought that I would have one with the links to the two other pages of which one will contain the datasheet which contains all the information about the pizzas and there prices and the other will contain the order sheet which will calculate the prices and discounts of all the orders made by the user..

And I think that it will look a bit like this:

After I had thought carefully about the design I thought that I wouldn’t use the design above because it would have too many pages and if the database started at the datasheet then it wouldn’t waste time by you having to press a button linked to it so it would be more efficient if there were only two pages the datasheet and the order sheet. I think that it will look a bit like this:

Implementation

This design is different than the first design that I came up with, this is because I thought that the first one had to much on it like the names of the customers. If you go down the page you can see the different stages leading to my finished design.

Stage one: this is when I had a problem with my v lookup in certain cells, and it would not work no matter what I did, so to resolve this problem I just deleted the cells that were giving me problems and entered in the formula in the new cells and then it finally worked.

Stage two: this is when I decided that I would put some colours in and then I thought that I should put the companies colours in which as you can see are light orange, blue and a dark orange.

Stage three: for the final thing I brightened up the name Pantry Pride Pizza Delivery by making it white and in a different font which I thought looked more attractive.

Evaluation

These are the objectives that I used in the beginning of my project:

• the spreadsheet should be neat and easy to use

The system was very easy to use as Mr. David had no problems understanding how it was used.

I could have made it better by writing out a manual to make it even easier to understand if the user forgot how it was done he could always go to the manual.

• the system should automatically add up the sum of the money for the pizzas

This worked perfectly to plan with no problems after I had sorted out the problem with the v lookup.

I don’t think that I could have made it any better than it is now, so I am quite happy with the way it turned out.

• the system should print out the invoice within  10 seconds

This worked with the right printer and caused no problems.

I could have made this better by getting a faster printer but this would be too expensive.

• the price automatically appear with the name of the pizza

This worked perfectly as excel is designed to do this with the right formula.

I don’t know any ways to make this better on the sheet.

• the sheets should be protected to avoid anyone accidentally deleting any information or formulas

This worked well. I added in two passwords for Mr. David, one to enter the file and one to modify so it would be very difficult for someone to change any of the information on the actual sheet.

• the system should have a sheet that looks good and contains the company logo, and stores information of the available pizzas and their prices and another one to do all the working out of the prices and the taking off of discounts and any other adding up that needs to be done

This has been achieved as you can see in my implementation stage and it has been done do the satisfaction of Mr.David.
