Herriard Pty Ltd Case Study
Introduction
Herriard Pty Ltd is a company that manufacturers office furniture for businesses. It specialises in office fit
outs and most of the production is made to measure. It produces desks, cabinets, cupboards, shelves, etc.,
in a variety of wood types and melamine finishes. It prides itself in its craftsmanship and currently all
design drawings are produced manually and there is no automation of the factory.
There are sales offices in Sydney, Melbourne and Brisbane. The manufacturing takes place in Wollongong
(NSW) and furniture is shipped using contract hauliers from the factory direct to the customer’s site. The
head office is also in Wollongong on the same site as the factory.
Herriard also purchases furniture such as chairs so that it can provide the client with a one-stop furniture
facility. It started seven years ago and has grown steadily over those years with all growth financed
internally. In the last two years sales really took off and increased by 40% each year. It now has a turnover
of $35M and around 1000 customers.
Staffing
There are head office/factory staffs of around 30 and the following organisation chart shows the senior
managers.
Excluding the managers shown, there are 5 people working in Finance, 3 in general administration. There
are 15 people working in the factory and 2 in HR.
In each branch there are managers and staff as shown in the table.

Sales office activities
Each sales office has account managers who spend time on the telephone calling prospective customers,
visiting customer sites and also working in the sales office. They have some basic brochures but most of
the sales are made to order. Customers may also walk in ‘off the street’ to visit the showrooms, which
contain examples of the furniture produced laid out in office displays. The offices have been strategically
located in areas where there are many business offices such as North Sydney. Each customer will be
allocated an account manager who will look after that customer.
Once a customer has expressed interest in the furniture the account manager will obtain the details,
1/25/2020 [In Process] 53077 – Assessment 1 – Written ReportInstructions:This
https://www.australiabesttutors.com/Recent_Question/53077/Assessment-1–Written-ReportInstructions-This-is-an 5/17
measurements, style, finish, etc., and produce a simple diagram of the requirements. The account manager
should also be able to give the customer an estimate of the likely price at this stage. When this ballpark
figure is agreed with the client the diagram and sales notes are passed to a designer, also in the local
office, who will develop the detailed plan which will be used in manufacturing. The designer will then
work out the final price for the customer. This may require the designer to contact head office to check
prices, availability, etc.
Once this plan has been completed the account manager will usually visit the customer, or get the
customer to come to the office, so that the customer can sign off the plan as representing their
requirements. A 20% deposit is asked for and a handwritten receipt is given to the customer.
The agreed plan is then sent to Wollongong to be manufactured.
If the client has ordered other furniture which is not made by Herriard then the local sales office will place
orders on the distributor and will ask the distributor to hold the items until the bulk of the Herriard
furniture is ready to be shipped to the customer.
Purchasing
There are three types of purchasing processes, which are currently performed independently.
Factory
The factory maintains small amounts of raw materials but since Herriard prides itself in making furniture
in many different finishes it normally orders in sheets of timber or melamine when it gets the customer
order.
When the customer order is received a clerk at the factory will check the design and then work out the
materials that are required. These will then be ordered specifically for that customer.
Sales offices
Each sales office will place orders for items that customers require which Herriard does not manufacture.
These tend to be local suppliers and each office is free to negotiate their own terms.
In addition each office has a budget for other purchases such as office supplies, sundry requirements, etc.
Any item over $2,000 has to be approved by the head office.
Head office
All other purchases are made through head office.
Computer systems
Herriard has the following computer systems in place:
Location Hardware Software Used for
Head Office 15 PCs, on average about two years old. All networked together. One Windows Server 2003
and all others running on
Operating System Windows XP
Office suite,
Accounting software with inventory module. Accounting and finance, letters and
documentation, keeping track of materials in the factory.
Sydney Sales office 3 PCs used standalone Windows XP and
Office suite Letters and quotes.
Melbourne
Sales office 2 PCs used standalone Windows XP and
Office suite Letters and quotes.
Brisbane Sales office 2 Mac computers used standalone Windows XP and
Office suite Letters and quotes.
With such a small company no one has really been responsible for the computers and each sales office has
been allowed to do their own thing provided they had the budget to cover the cost. At head office, each
department had acquired PCs and about two years ago they were networked using the services of a local
Systems Integration firm called Wollocomp who has provided support as required since then.
Customers
Customers may be analysed as small, medium and large. The small customer may be a small organisation
with two or three offices to equip. The average order value for these customers is around $7,000.
1/25/2020 [In Process] 53077 – Assessment 1 – Written ReportInstructions:This
https://www.australiabesttutors.com/Recent_Question/53077/Assessment-1–Written-ReportInstructions-This-is-an 6/17
Large customers may be equipping whole buildings or floors of buildings and these average orders are
around $75,000.
Medium customers average around $20,000 orders.
The breakdown of customers is shown below:
Location Small Medium Large
Sydney 400 75 10
Melbourne 300 40 8
Brisbane 100 15 2
The business is such that once a customer has purchased from Herriard they may go two or three years
before they need any more major purchases and so each year the sales force has to find new customers.
There would be around 1000 to 1200 invoices issued each year.
There does not appear to be any seasonal trend in the sales patterns and sales are fairly even throughout
the year.
Purchases
To obtain the best prices Herriard has restricted the purchase of raw materials to a few suppliers. Each
order is normally for the equipment to be made out of the same material and so would generate maybe
four or five purchase orders. Herriard will keep in stock, items such as handles, hinges, locks, etc. and
again only purchases these from a handful of suppliers.
Since each office is allowed to make use of local suppliers for items not manufactured by Herriard there
are also several suppliers for each sales office. The details are shown below:
Location Suppliers
Head Office Manufacturing 20
Head Office Administration 60
Sydney 30
Melbourne 20
Brisbane 15
It is rare that a sales office will purchase from the same supplier as used by another sales office since each
will use a local supplier.
The sales office will place an order with the local supplier but all financial transactions are processed at
Wollongong. When the goods are received a copy of the delivery document is posted to Wollongong and
the supplier will send invoices directly to Wollongong.
Payment to suppliers is normally made within thirty days.
Sales processing
When the customer signs the contract a copy of the contract, the design and the deposit is sent to head
office and the originals are filed in the sales office.
The cheque is banked and the transaction is recorded in a spreadsheet. It is not put into the accounting
system at this time since cheques cannot be received unless there is a corresponding invoice already in the
system.
When the designs are received in Head Office they are checked and an estimator works out the
requirements for the design. This is costed and compared to the quoted selling price. Herriard normally
expects to make 40 to 50% gross profit on orders.
The order is passed to the manufacturing manager who looks at the factory schedule and estimates how
long this will take to make and when it can be competed. A fax is sent back to the sales office so that the
customer can be informed and the delivery and fit out scheduled.
The sales order will be entered into the accounting system.
Meanwhile, in the sales office a list of non-Herriard items is compiled and these are given to a clerk who
will contact the appropriate supplier and confirm prices and times for delivery. Orders are placed on these
suppliers.
In the factory the orders are scheduled basically as they are received and placed in a large in-tray. The
foreman is responsible for ensuring that the carpenters are kept busy and will allocate the orders when
required.
1/25/2020 [In Process] 53077 – Assessment 1 – Written ReportInstructions:This
https://www.australiabesttutors.com/Recent_Question/53077/Assessment-1–Written-ReportInstructions-This-is-an 7/17
When the order is completed a fax is sent to the sales office detailing the date of delivery. The sales office
will convey this information to the customer and organise final delivery details. At the same time the
suppliers of other furniture will be contacted and their deliveries scheduled to coincide with that from
Herriard.
When the furniture is delivered a dispatch document is created and a copy of this is sent to the accounts
department. When this is entered into the system an invoice will be generated and this is mailed to the
customer.
Terms are payment within 30 days and debtors are tracked in the accounting system.
Herriard Pty Ltd Report Guidelines
Herriard Pty Ltd has been conducting business at a lower than ideal profit margin due to inadequate
Network and systems security policies and procedures. Head office has provided an overview audit of
current problems affecting the business that need to be addressed.
Information Technology Goals at Herriard Furniture Pty Ltd
The following targets have been set at Herriard Pty Ltd:
? Inventory Management System to solve problems like processes based on paperwork, high human fault
rate, untraceable process and tracing of the inventory losses, no efficient logging systems
? To have equipment operational for 99.5% of the time
? Downtime on primary servers should be covered by appropriate secondary sources of information, in
light of the recent unfortunate event of the server disk becoming full.
? More secured staff system. (in terms of the permissions and access rights given to them) ? The internal
network of head office which they use needs to be more secured.
? They also want the system and network protected from the external threats which may cause trouble in
the network functioning and lead to monetary loss.
? A secure means of notifying head office of that a local sales office has ordered stock from third party
suppliers.
? A clear escalation policy and procedure is to be in place to handle the situations beyond the scope of the
problems that IT staff have been trained to accommodate (in line with company guidelines)
? Given the present company security policy of email data to desktop machines being accessible only from
the office computers, the company wants to provide staff with a form of free roaming email access.
? The company has been experiencing a high frequency of interstate administration calls. This has in turn
caused a rather high telephony bill between the three offices, each averaging sixty dollars a day on
interstate phone calls, which is diminishing the budget for other services. The head office has ordered that
a solution be implemented as high priority. Notably suggested by Wollongong computer support was the
possible implementation of a VoIP system, to allow more phone calls between interstate offices without
incurring high costs, and to allow further customization and better communication of the existing
telephony system across the country.
? The Information Technology advice on the VoIP system obtained must state which Voice service
provider will best provide service to Herriard as a communication carrier and why. An in-depth
comparison is requested for the purposes of keeping the management and finance department content
about the provider.

22. Policy Maintenance
The IT Manager has the authority to initiate recommendations for revisions to this policy, which are then
approved by the Chief Executive Officer. Any requests for amendments to this policy should be forwarded
to the IT Manager through the Chief Executive Officer. Changes to the policy will then be evaluated and
implemented as stated above. All staff will then be advised of the amendments at the earliest opportunity.
A sample IT Solution (according to Herriard’s IT goals):
Software based Inventory Management System (IMS) is designed and implemented.
Determination of the Requirements
Inventory Management System (IMS) is generally used by IT Office/Department or Accounting Office of
a company. Therefore, searching the basic needs for implementation is the first step of IMS design.
Several meetings with IT Office and Accounting Office are arranged. Accounting Office needs detailed
reporting tools, detailed categorization and declaration of specifications on each item, purchasing and
billing info. The Information Technologies Office needs another module except the requirements of
Accounting Office. The module is about the interior maintenance and exterior product service flow. For
interior maintenance flow, there will be a section. This section will be available for all users. Basically, a
maintenance request will be created by the users, and the IT Office will respond to these requests. Finally,
it is necessary to consider the end user’s needs that are also important part of the IMS software design.
This leaded to use barcode based system.
Software Requirements
After gathering all the requirements and information next state was achieved which was quite important
for the project. If the decision was not well organized, it may cause re-organization and programming the
algorithms at the beginning.
At the beginning, first thing to decide is the general structure. It was decided to build the system browser
based. The system is going to be used by a large number of users, so it should have been designed to be
reachable for every single user, instead of having a desktop application for every user. Also if considered
that Herriard already has a similar system—Information Management System, it would be easy to
integrate. By using the user database of the existing systems, the login parameters are ready to use for
IMS. So, the portability would be provided.
The next step is to decide the language to implement. There are several parameters to decide in realization
period. First is the compatibility, and then came the time which is related with ease of implementation. In
the light of these redirections, we decided to use PHP as the language to code the system. It is compatible
with the other software and hardware, and it is easy to integrate everything. PHP is an open source
environment and there are a large range of resources to get help. Information Management System is
already developed by using PHP. It was also decided to use AJAX to obtain a faster system. In AJAX,

only the needed data is being requested from the server, this method speeds up the loading time. While
thinking how to code with PHP, it was decided to use Model View Controller based structure. This
structure separates the visual design.
Code Igniter Framework was also used for decreasing the amount of code lines. It gives ability to program
faster with less effort. Code Igniter also supports MVC structure. So it was decided to use PHP, MySQL
and APACHE trio. MySQL was used as database. It is the best fit for PHP and it has the open source
advantages. “innodb engine” was used because it is transaction based, which is necessary for the project.
To get the user data, it was required to communicate with the database of company, which is programmed
by ORACLE. It was needed to have the login information to have a fully integrated system, and also
several details such as e-mail addresses and so on.
Barcode System
A barcode is an optical machine readable representation of data, which shows certain data on certain
products. There are different types of barcodes, some of them have to be worldwide unique and need
license. ‘‘code39’’ was chosen because first of all, code39 does not need license, have the possibility to
print for unlimited products, supports full ASCII, number, letter and special character usage (capacity of
26 capital letters, 10 numbers, 7 special characters). And also it was the easiest to read and was the best fit
for the barcode generators for PHP. The barcode generator which was found was the one compatible with
PHP. It was using PHP’s GD Graphics Library. The script was used and modified it to be able to print
serial barcodes. It prints barcodes in increasing order (in multiple prints) on the screen, and sends to the
printer. The script is distributed under GNU License. And the hardware part of the system is out of a label
printer and a barcode scanner. Barcode scanner is a USB connected model. It scans the barcode, writes to
the field where the cursor is, and presses enter.
This function eases the usage. So the only extra hardware to be used by the staff will be a barcode scanner
after the system is implemented to the enterprise.
Implementation of the System
Database Design
The most important component of the system implementation was the database design. It can be easily
realized, if we consider the amount and the scale of the inventories. To have a strong and flexible system,
the design must be well studied.
Two important structures of the system were the database and the Graphic User Interface (GUI). In
between,
JavaScript and PHP provide the connection and interaction. GUI is located in the view section. With
XHTML and CSS, the visual part is generated. JavaScript updates the HTML by the data sent by other
layers and connects the GUI with working PHP structure. An Admin Panel called ‘‘CompleteLiquid
admin control panel’’ was used. It was suitable for our MVC structure.
With CSS and other related modifications, it could be arranged to the system. In the controller layer,
dataflow decision codes take place which were JavaScript and PHP. And in the Model section, PHP logic
base code was placed. All codes were produced with Code Igniter framework.
Modules
IMS was designed as several modules, separated by their specific roles and functions. There are six
modules in the system.
1. Definitions/Setup
2. Inventory Management
3. Service Management
4. Maintenance Management
5. Debit Management
6. Deposit Management
Fig. General IMS architecture
The functions of each module are explained step by step below:
Definitions/Setup

This module is the most important part of the system. Because if the definition of the enterprise is not
implemented correctly to the system, it wont work efficiently.
To have a successful, operational system, introducing the enterprise to the system is a must. And this is the
first step of implementing the system to the enterprise.
In this module, there are four sections, which are mentioned below.
a. User Setup
b. Location Hierarchy
c. Categorization
d. Suppliers and Maintainers
(a) User Setup
In User Setup Menu, System Admin can create, edit or delete a user from the system.The table below is
the user creation form. System admin can choose the role of the user from the picklist on the bottom. (b)
Location Hierarchy
The Location Hierarchy section is the place where you set the ownership hierarchy of the enterprise.
System Admin can create one sub unit under another by choosing a unit.
(c) Categorization
In this section, a categorization of the inventories in the enterprise is being created. First step is the main
categorization. The second step is related titles, and the last one is the specific keyword. User can add
subcategories under each category after choosing it.
(d) Suppliers and Maintainers
In this section, System Admin can define inventory suppliers and the maintainers of each supplier. To
define a maintainer, user can choose related supplier, and add maintainers under it.
Inventory Management
This Module is the centre for all processes about incoming inventories. Module has two sections: a. New
Registry
b. Instant Registry
(a) New Registry
If the inventory is ready to record, this is the section to use. First step is to print a new barcode for the new
inventory. The system pops out an alert. After this alert, there comes the next page, where the user has a
button to print to confirm the barcode by scanning it into the field.
After confirming the barcode, the next page is an information form. There are Category, Supplier, barcode
number (auto entered), serial number, price, receipt date and extra info fields to be filled. Then, the next
step is the product specifications part. The first part has the title group of related inventory category. The
user can switch between titles and choose related specifications from the second list. Then the chosen
specifications are added to the last field as related keywords of the inventory. And after clicking the
button, the entry is on the database, and in ready state for other actions on the system.
(b) Instant Registry
This section allows user to print several barcodes when the inventory is not ready to record. For example,
it may not be possible to bring label printer everywhere. So the user can print as much as needed, the
system creates empty fields in the database to be filled in inventory registration process. When these
barcodes are scanned, register page comes to complete the register, and the normal registry flow
continues.

Service Management
Interior maintenance may not be sufficient, or may cause warranty problems, when inventories have
technical problems. In this situation, they may need to be fixed by authorized maintainers. This module is
for management of exterior maintenance.
There are three search fields in this section with Barcode No, Serial No parameters to reach the inventory
or User Name parameter to reach the inventories of a specific user. After reaching the inventory, the
window below comes to take action.
The user can view the service history of the inventory, and open a new service record to send the

https://www.australiabesttutors.com/Recent_Question/53077/Assessment-1–Written-ReportInstructions-This-is-an 15/17
inventory to service. There is a pick list to select the service firm, and an info box to write a brief
explanation. Then, another ‘‘close service record’’ link appears on the inventory information table.
When the inventory is returned from the service firm, user reaches the table below to close the record.
User can write the information, process done to the text field and closes the service record, which will be
seen in service history from that moment. Also user can use the ‘‘User Name’’ search box to reach a
specific user, and list the inventories on users debit. Then, the same program flow can be used to take
action.
Maintenance Management
This module is for interior inventory maintenance flow. There are two sections: first is to create new
maintenance request for device users, the other is maintenance task listing for related worker.
The user will fill the required fields and then the request will be an active task for maintenance staff and
will drop in their task table that they have on their interface if a staff member is assigned to the task.
Otherwise, the task will drop into task pool. Then staff deals with the problem, and closes the task after
writing info about actions taken. If the problem gets fixed before maintenance arrive, the user also can
close the task.
Debit Management
This module sets the relationship between users and inventories. Basically, assign an inventory to a user,
and performs other operations based on debiting.
Deposit Management
This module manages the barrowed items. Assign the inventories to desired person. There is also a chance
to list deposited inventories in this module. It is a manner of tracking.
Users
Users have an authority hierarchy according to their section, and they are only allowed to use related
modules except system admin. System admin has the authority to use every module in the system. In order
to prevent improper use, the system logs every act, every edit. Although users can only use their modules,
they can also use some other features of the system. There are three user types and use case diagram of the
IMS has shown above:
1. System Admin
2. Technical Users, Accounting: Has authority on Inventory Management, Deposit Management, Debit
Management, Service Management and also reporting features.
3. Basic Users: Basic users are only able to report their debit inventories and request service for them.

Login
The first step is ‘‘login’’ to the system. There are two login alternatives. First one is the system
management, the other one is the end users. The login data is gathered from University database, so the
users can login the system with their existing username and password.
Complete software architecture of IMS software has given in Fig. above.
