Read through the outline and write down each required function.

i.e. There are at least two types of stated users: customers and accountants. Now what can each do or have done for them?

Quote:

The system must support two types of customers. There are those who pre‐pay a fixed
amount for their electricity and will receive a card through the post to insert into their
meter. These customers will incur a quarterly charge of £25.
There are also billed customers who receive a paper bill every quarter. A bill includes a
quarterly £20 charge plus a consumption (use) charge of £0.07 per unit. Consumption is
calculated from meter readings taken recently and at the end of the previous quarter (a
customer is expected to enter this data). The payment should be made within fifteen days
of the end of present quarter. Every payment must be checked for late payment and a £10
fee should be added for overdue payment. A discount of 10% will be applied to all
customers who pay their bills within seven days of the end of the present quarter.
Both sets of customers maintain accounts with the electricity company and are identified by
unique reference numbers.
You are also required to log the time a customer spends to make a payment. A customer
should be able to request a report about the payment, which should be in a printable
format. The company accountant should be able to view the same report.

I believe the methods would be:
Send fix bill
Send variable bill
Get usage
Recieve payment
Check date
Send late bill for £10
Update bill by 10%
Log in
Log out
View report

The accountant and customer use the same method since:

The company accountant should be able to view the same report.
