The aim of this assignment is to give students a deeper understanding of the process involved in
requirements engineering through:
Catamount Pty Ltd is a successful outdoor and camping gear store who now wish to expand
their business by staring an online shopping system to attract more customers since online

Functional Requirements:
The online shopping system shall address the following requirements:
Maintain an inventory
 The inventory stores all items currently sold by the store
 Every item in the store has a name, product description and a price.
 Items in the store are grouped into categories: clothing and camping gear
 Clothing items include shirts, pants, jackets, swimwear, boots and accessories. Items such as
gloves, beanies etc. are grouped under accessories
– All clothing items also have a size and colour.
– Allowable sizes are ‘S’, ‘M’, ‘L’.
– Colour is provide as text e.g. ‘blue’
 Camping items include tents, electrical and miscellaneous items. Miscellaneous items
include foldable chairs, buckets etc.
– All camping gear also have dimension and weight
Search inventory
 Allow a customer to do a search of all the items currently sold by the store.
 The search will display the item name, product description, quantity currently in stock
 Allow a customer to do a search by category (e.g., clothing or camping gear) or by subcategory
(e.g., pants, tops, miscellaneous etc.)
Maintain periodic discounts for the various items in the store
 The store would like to associate periodic discounts to their items
 Currently, discounts can be grouped into individual and group discounts
 An individual discount can be a flat discount or a percentage discount.
– A flat discount reduces the current price (after any previously applied discount) by a flat
amount e.g., ‘$20.00 off the current price’
– A percentage discount reduces the current price (after any previously applied discount)
by a percentage ‘20% off the current price’
 A group discount is implemented as a ‘BuyXGetOneFree’ strategy, A ‘BuyXGetOneFree’
discount reduces the price of the next same item to $0 for every X Items bought. So for
example, Buy 4 gloves Get One Free means 4 Items are purchased at the current price, and
the 5th of the same Item is free
– Note: A group discount will only apply to items of the same sub-category (e.g. accessories,
pants etc)
 Discounts on an item can be chained together, with the most recently added one applied
Admin user features
 Can add a new item to make it available for purchase
 Can remove an Item, effectively making it unavailable for purchase
 Can add multiple Discounts to an item
 Can remove the top level Discount (most recently added) off an Item

 For each item in the shopping cart,
