6COM1042: Software Quality Assignment1 – 2022/2023
An empirical evaluation of an effort estimation technique
Overview (The following is a hypothetical Case Study)
As part of your Software Quality assignment, you have been asked to build an online Vintage
Film Rental System for a Nostalgia Society. This is a system that rents out vintage movies
that can only be watched on film reels. The movies are stored in delivered in film canisters.
The following is the specification for the proposed system:
Specification A
Specification for an online Vintage Film Rental system:
Registered customers will login to the system using their login details. Once access has
been granted, customers will query the System as to the availability of Vintage Film titles.
Customers can also query the status of their rentals (that is, how many Vintage Film Titles
do I currently have on hold, how many are overdue? etc...). These two functions are
instant enquiries that generate results immediately on screen. Customers can then place
an order for Vintage Films by selecting Titles. The order is despatched to customers within
24 hours by an Order Clerk. Where needed, customers can also generate a report of their
borrowing patterns, in a particular year. At the end of each working day, an Order Clerk
generates a report of orders for the day to prepare a dispatch list for the next day’s
delivery. At the beginning of each day, the Order Clerk updates Customers’ accounts with
all Vintage Film Titles that have been returned. When new Titles are discovered, the
system is updated with this information from a stock system that is separate from this
rental system. These are the ONLY functions that this system conducts.
The following are the identified sub-functions of the system specified in Specification A.
External inputs (3)
o Login Details
o Place Orders
o Update Account
External outputs (2)

, Question 1) Assume that all the weightings for the above sub functions in Specification A
are average with the exception of the Internal File, which is Complex and calculate the
Unadjusted Function Point count for the specification above. Remember to detail the stages
of your calculation by showing the formulae and standards used to derive your solution.
