TASK 2 - REQUIREMENTS DOCUMENTATION
When the customer requests to borrow a new book, his/her details are verified by
the librarian. If the borrower returned the book before or on the day of the return, there
wouldn’t be any fine. However, if the borrower returned the book late a fine will be
instigated on the borrower. The fine amount depends on the number of days the borrower
is behind the actual return date. For example, if the borrower delays the return of his/her
book by a week or less he/she will be charged $1.25. If the delay is between 1-2 weeks, the
borrower will be charged $2.50 and if there’s been a delay of more than 2 weeks the
borrower will have to pay the due of $5.00.
While these are the cases of book delay, if the book which is loaned by the borrower
is lost, the borrower can inform the same to the librarian. In this case, borrower is
compelled to get a new book of the same edition to compensate for the loss of the old
book. Also, the late fines can be avoided by borrower if they report the loss of the books
before the return date. However, the loanee will have to pay the fine if he/she reports the
loss of the book after the due date.
Separate fines are generated for the book if it’s found damaged or if the pages are
missing from the book. Borrower will be forced to to replace the book with a new one. Also,
the maximum debt that a borrower can have including the fines is $25.
