User Requirements
This was the user requirements from the Unit 14 Event Driven Programming program:
1. The car chosen, colour and how long for. The customer should be able to choose from four
categories of cars (wedding, classic, off-road, and sports.) The customer should also have the option
to be able to choose the colour that the car should come in (blue, dark green, dark red, red, silver,
and white.) The customer should lastly be able to choose when they can pick the car from especially
for you and when to drop the car off again when the hire period ends.
2. Add any extras (service) that the customer wants. The customer should be able to choose between
3 services (gold, silver, and bronze.) The gold service comes with champagne and a chauffeur, the
silver service comes with a chauffeur and the bronze service comes with nothing. The 3 prices of the
services are (gold – 50% added to price, silver – 30% added to price, and bronze – 0% added to
price.)
3. Date of the invoice that was created. The customer should be able to know when they phoned the
company up asking about a car for hire. The date of the invoice should go onto the pricing form so
they will know when the invoice was created.
4. Customers contact details. The user should be able to take the customers personal contact details
such as title, first name, surname, phone number, email address etc. A form should be dedicated to
this so the user can fill it in.
5. Sign in page for the user. The user should be able to have a sign in form that allows the user to sign
into the whole program using a provided username and password.
6. Start and end days of the hire and this includes how long for. The customer should be able to pick
how long the hire period should be for with the car he has chosen. It should be represented on the
pricing form so that both the user and the customer can see it.
7. Show a 10% discount if hired for longer than 7 days. The customer should be offered a 10%
discount if they have hired the car longer than 7 days. This should be calculated in the maths of the
pricing form code, so that it can be seen on the receipt when it has been printed.
8. Grand total of the hire cost. The customer should see how much the total cost is going to be
without any VAT/Discount prices that have been applied. It should go onto the pricing form so when
it is printed off, the customer will see it.
9. Add any surcharge prices (service). The customer should be able to see how much the surcharge
pricing was and the customer should also be able to see it added to the total cost. It should go onto
the pricing form, so the customer will see it when it has been printed off for them.

10. Help for the user. The whole program should have a help form, which will guide the user if they
have any difficulties when operating with the current form. For example, the user should be able to
press a button and that will take them to a certain form, they can therefore read what they need
help with, then they can go back to the form that they were on previously.
11. Validation so the program is robust. The whole program should have validation on certain forms
so that the program is difficult to get into by hackers, or hard to break by other users. For example,
the sign in form should have validation where it requires a username and password to enter the
program. The contact details form should have validation where a field cannot be left blank.
12. The company name and logo. The program should have the company name and the logo on
every single form, to represent who the forms belong too, and to give a consistent feel.
USER INTERFACE DESIGNS
These are the user interface designs for my Unit 14 Event Driven Programming program which I used
Balsamiq to create the designs:
This is my sign in form and this form is the first one that loads up, it lets the user sign in to the
program. A textbox allows the user to type the username and password into the form, and then they
press the sign in button to go the contact details form. The company logo and the company name has
been put onto all the forms so it’s a consistent design throughout the program.
This is my contact details form, it allows the user to type the customers contact details in to the form
such as Forename, Surname, Phone Number, and Address etc. The user is also able to press the help
button which will take them to the help form which they can find guidance on the form. When the
user has finished filling in the customers contact details, they can press the car chosen form which
will take them to the car chosen form.
