Note: The case study below may not provide all of the information necessary to complete

the assignment. Students will have to use their personal experiences to complete some

aspects of the assignment. Students may also seek clarification from their tutor during

tutorials or office hours.


City Glaziers


City Glaziers is a medium business operating in and around the Melbourne metropolitan area.

The company supplies glass for windows and doors, and other structures within the Melbourne

area. Glass can be ordered in bulk as part of a construction project, or in smaller quantities as

replacement for broken windows, doors containing glass, bus shelters, and larger areas such as

internal feature walls etc. The company began by operating in the Melbourne CBD originally,

but has since expanded its operations to include most of the surrounding metropolitan area.


The company has built a reputation for providing high quality glass, as well as excellent service

to it customers.




The owner of the company, Robert Johnston, began the company in 2001, operating a single

glaziers truck from a warehouse in North Melbourne. Robert operated successfully in the

Melbourne CBD, providing a high quality service to his clients. The business has steadily

increased over the last 14 years, and Robert now operates a fleet of 11 glazier trucks and has

expanded the operating territory to cover the entire Melbourne Metropolitan area.


The Business expansion has included a move to a large warehouse and glass preparation area,

with the head office located next door in a modern office block. The business seems to be

expanding and Robert is now beginning to consider opening franchises in outer Melbourne areas,

to be serviced from the central warehouse operation. Robert also has arranged to deal exclusively

with a large glass manufacturing plant, Melbourne Glass Plant, located in an outer Melbourne

suburb. By becoming a large customer of Melbourne Glass Plant, Robert gets lucrative discounts

which he can pass on to customers, helping him compete in this competitive environment.


The size of the business has now reached a stage where Robert can see major issues arising. As

the business has grown, the operations have become more complex, and this will only become

more so if franchises are added to the current operations.


Robert has decided to employ your team to investigate the business needs and to conduct an

initial feasibility study into the possible options for computerizing part or all of the operations.

Description of the Current System


The current system is a manual based system which has served the company well, but is now

becoming outdated and causing bottlenecks due to the increased workload demand. Currently the

business has two main areas, the Large Projects Section, and the Repair Section.


Large Projects


Anna Fields works for Robert in heading up this section of the business. In the Large Projects

section Anna and her staff put together quotes for whole jobs by responding to a construction

companies RFQs (Request For Quotes). The quotes are for complete supply of glass needs for

major construction projects such as new building projects or reconstruction projects on large



The team begin by identifying construction projects and responding to the company RFQ. The

team will contact the company to request precise specifications and put together a quote for

materials, delivery and installation. If the quote is successful, City Glaziers will then develop a

timeline document for approval by the company, and begin the ordering process. A timely order

will be placed with Melbourne Glass Plant for the raw material, and these will be delivered to the

warehouse. A Work Order is generated which includes a copy of the original quote and

specifications and sent to Glass Preparation, where the work will begin in preparing the glass

panes according to the specifications and delivery schedule.


Once the glass is prepared and cut to size, an Installation Order is prepared and a glazier truck

booked for the delivery and installation date.




Ben Hanscom is the head of the repair section, and also manages the Glazier Truck fleet.


Customers will ring in to the Repair section with requests for repair, or for replacement, and the

schedules will be checked to find the closest Glazier Truck. The repair request will be slotted

into the schedule of the closest truck, and usually result in a same day service. When the Glazier

arrives at a customers site, they will quickly check to see if the job can be performed

immediately, or if a special Work Order needs to be completed.


Each Morning, the Glazier trucks are outfitted with a standard compliment of glass sheets of

varying thicknesses and sizes. Over time this standard fit-out seems to cover a Glazier for most

of the day for their standard type repair jobs. The glass preparation area is responsible for

outfitting the truck each day with the standard compliment of glass, based on a compilation of





MITS 5002 Case Study

the completed Job Sheets completed each day by each Glazier. The only exception is when a

truck is specifically booked for a large project delivery and installation.


If a Glazier arrives at a repair job and cannot complete the job because they lack specific

materials, then a Work Order is completed and bought back to the warehouse so the Glass

preparation area can prepare the material for installation in the next day. If the Glazier can

complete the Job on the same day, then after finishing, they complete a Job Sheet, detailing the

material used so the Glass preparation area and replace the material used on the truck for the next

days work schedule.




When City Glaziers are awarded large scale projects with successful RFQ submissions, they are

given accounts with the company that awards the projects. They receive payment by direct debit

after they submit invoices to the company for materials and time (as per the awarded contract).


For smaller repair and replacement work, when a Job is complete, as well as filling in the Job

Sheet to detail the used material, the Glazier will also prepare an invoice to give to the customer

on the spot. The Glazier also returns a copy of the invoice to head office at the end of the day

when they return to the warehouse. The customer can choose to pay via the terms on the invoice,

7 days payment, or receive a 5% discount and pay on the same day via credit card, or personal

cheque with identification. Some Customers have accounts with City Glaziers, and will receive a

monthly statement through the post. These customers have longer terms, such as the end of the

month in which the statement is issued.


When a customer payment is received, a copy of the payment is sent to the head office accounts

section, where the payment is matched against the invoice and a receipt will be issued through

the post.


Regular reports need to be generated to list those invoices over their due dates that have not been



Supply Orders


The Glass preparation area in City Glaziers is responsible for collating all the Job Sheets and

Work Orders so that stock levels can be monitored and stock re-ordered when levels fall below

threshold levels.


Also, large project orders will need to be dealt with quickly so that existing stock levels for the

repair and replacement section is not affected

A number of issues have arisen that have prompted City Glaziers to contract you to look into the



• It is difficult to keep track of the Work Orders and Job Sheets to re-order stock before it

falls below threshold levels.


• When Glaziers need to raise work-orders at a client site because they don’t have the

material, it is not till the end of the day when Glaziers return to the warehouse that these

can be collated to begin preparation for the next day, resulting in some delays.


• Sometimes paperwork has gone missing for large scale projects and needs to be tracked

careful to avoid delays and loss of awarded contracts


• The fleet of Glazier trucks needs to be managed better as sometimes with the paperwork

double booking can occur and result in frustration and delays


• Additionally, we need to keep better track if kilometres travelled so trucks can be

services in a timely manner.


• Delays in sending paperwork to our suppliers can cause delays in order processing and

result in longer delivery times of stock.


• The level of paperwork is increasing and the accounts department is having trouble

keeping up with the timely production of monthly statements, processing of payments

and general financial reporting.


• With customers beginning to ask for different methods of payment such as email, PayPal

etc, we need to look at incorporating this into our business processes somehow

The turn-it-in similarity score will be used in determining the level if any of plagiarism. Turn-it-in

will check conference web-sites, Journal articles, the Web and your own class member

submissions for plagiarism. You can see your turn-it-in similarity score when you submit your

assignment to the appropriate drop-box. If this is a concern you will have a chance to change

your assignment and re-submit. However, re-submission is only allowed prior to the submission

due date and time. After the due date and time have elapsed you cannot make re-submissions

and you will have to live with the similarity score as there will be no chance for changing. Thus,

plan early and submit early to take advantage of this feature. You can make multiple submissions,

but please remember we only see the last submission, and the date and time you submitted will

be taken from that submission


Please Note: All work is due by the due date and time. Late submissions will be penalized at the

rate of 10% per day including weekends.
