Information Management and Security
Business Brief for Tasks 2 & 3
Graeme’s Music School is a small, but rapidly growing business operating out of Geelong. The business began as a means for Graeme to follow his passion for playing guitar and offering music lessons for both adults and children. As much as he enjoys playing live music, it is not a very profitable occupation, so Graeme also teaches music.
Within a year of beginning this business Graeme was approached by other teaching musicians looking for opportunities to teach students various instruments and singing styles. Not long after, he became an agent for selling Australian made acoustic Maton and Cole Clark guitars (see:www.maton.com.au and www.coleclarkguitars.com). While most of his guitar sales are mostly local from Victoria, there have been online sales to all Australian states and territories
Three years later, Graeme finds his online and off-the-shelf acoustic guitar sales is making a reasonable income from the 20% commission that he charges both
manufacturers for one-of orders for individually built, bespoke guitars made for
individual orders and 50% markup for regular acoustic guitars sold off-the-shelf on the business premises and through the online businesses.
The music school side of the business has also expanded, and he has 15 musicians who are teaching music into groups of students organised into classes;
and the demand is still increasing. Approximately two thirds of the classes are for school age children, and one third is for adults. The music school keeps track of which musicians have a “Working with Children Check” card and its expiry date, and the age of musicians to ensure that only approved adults can teach children
Graeme’s Music is now carrying out the following core business operations:
Acting as an agent for Maton and Cole Clark Guitars to arrange orders for bespoke acoustic guitars
Online and off-the-shelf sales of regular acoustic guitars
Booking students into classes that music teachers teach
Booking music teachers to teach classes of students
So far, his business has been operating with temporary notes scribbled on notebooks in combination with a series of disorganised spreadsheets. But these tools are becoming inefficient and increasingly inapt at managing the growing demands of the business. A transition to an information system is urgently needed

NOTE: The design of any payments system is outside the scope of this work.
TASK 3: Security Research Report
