3SYSTEM ANALYSIS AND DESIGN
1. Consultation
This agile and iterative methodology allows rapid changes and include adaptive planning,
delivers the software in short time and includes elf-organization (Satzinger, Jackson and Burd
2011). This methodology is flexible, and allows continuous improvements regarding the quality
of the software. As the OZES management system deals with user requirements that needs to be
changed from time to time, the following three agile methodologies can be used for developing
the information of OZES.
Methodology: Scrum Agile Methodology
Discussion: The scrum methodology includes interlocking steps as well as components
where the owner of the OZES can make the priority of the activities listed in product backlog
(Schmitz, Mahapatra and Nerur 2018). The methodology includes sprint backlog which includes
a wish of the owner and tries to implement the plan. Each sprint using this methodology is
completed in between 2-4 week and meeting are organized after a sprint gets completed.
Advantages: The advantages are listed below:
 This methodology is flexible as well as adaptive.
 Scrum methodology is creative and includes innovation.
 This helps to lower the cost.
 Improves the quality of the software.
Disadvantages: The disadvantages are listed below:
 Training is required for the project team.
 With this methodology, scalability is difficult.

4SYSTEM ANALYSIS AND DESIGN
Methodology: Extreme Programming Methodology
Discussion: This methodology is mainly used to increase the customer satisfaction. The
XP methodology mainly concentrates on the present requirement of the user rather than thinking
of future requirement. This methodology is centred on small development cycles and include
short releases (Rasnacis and Berzisa 2017). This methodology uses unit testing and include
frequent communication with the client. The Extreme development methodology includes
involvement of the owner of the OZES and establish a good communication between the
development team and owner of the OZES. User stories are also stated in this developments and
the owner or the client of the application software can prioritize the functions that are important.
This can help the OZES to state the most important features that are to be included in the system.
This methodology delivers the software in very short interval of time which might help the
OZES to launch the management system in 1 to 3 weeks.
Advantages: The advantages are listed below:
 Helps to save cost of Australian Electric Supply.
 The codes are simple in this methodology.
 The process that is carried out is visible as well as accountable.
 Includes feedback from the client.
Disadvantages: The disadvantages are:
 Focuses mainly on the codes instead of design.
 Does not measures the assurance of code quality.
Methodology: Feature Driven Development (FDD)

5SYSTEM ANALYSIS AND DESIGN
Discussion: The FDD methodology is considered as a model driven methodology having
short process of iteration. This methodology mainly starts by establishing the overall shape of the
software or the model (Schön, Thomaschewski and Escalona 2017). As the management system
of OZES needs to have requirement of developing the system, the development process includes
object modelling, FDD methodology includes this particular practice. The FDD methodology has
tight control on the development process that result in developing a tangible software.
Advantages: The advantages are listed below:
 This supports working of many teams in parallel.
 All the aspects of the project can be tracked by this feature.
 This system includes large team
 Provides progress tracking of development and includes reporting capabilities.
 Have excellent documentation
 Includes designing and code inspecting that results in providing high quality of
application.
Disadvantages: The disadvantages are:
 This methodology promotes code ownership.
 The iterations are not well defined in this methodology.
Recommendation: The best methodology that can be used for developing the
management system of OZES is the agile scrum methodology. This methodology will help the
company to improve the productivity that are in teams as well as will help to deliver the
information system in every 2 to 4 weeks (Rajagopalan and Mathew 2016). This method

6SYSTEM ANALYSIS AND DESIGN
includes team formation along with diversity, will includes a good communication in between
the team members, and includes frequent feedback from the owner of the company.
For developing the management system of OZES, the scum methodology will help to
control the scope of the project and will encourage the team associated with the project (Zewairi
et al. 2017). This methodology increases the transparency of team and includes good visibility to
manage the drawbacks of the system that is to be developed for the system. This particular
methodology is adaptive. The agile scrum methodology will help the developer of OZES to
interlock the steps and the components that are given by the OZES owner and also has the ability
to make priority to all the activities that are to be included in the system. The main methodology
that agile scrum method follows are using the sprint backlog system that also includes the wish
of owner about how the owner wants to implement it in the system. All the sprints that are used
in the agile scrum methodology are to be done in two to three weeks and after each sprint being
completed, meeting is organized for the system. This methodology has many advantages of
completing the project in a flexible manner and in an adaptive way. The scrum methodology is
very much creative in nature and also involves innovation. This methodology can help the
developer to complete the work with low cost and improves quality of software.

3. Memo
Date: May, 30, 2019
To: Executive Analyst
From: Business Analyst of Australian Electric Supply (OZES)
Subject: Implementing Management Information System in OZES
I am writing this to inform you that OZES is implementing an information system to manage the
business process of second hand selling in the business. The information system is already under
process and I am expecting to finish the project within 6 to 9 months.
As our company wants to extend its business process to second hand selling, I want to design the
human computer interaction system (HCI) by implementing the user centric design. As the

13SYSTEM ANALYSIS AND DESIGN
system will be used by you, you need to provide me with the detail requirements that you want in
the new information system. There are different processes that you perform for selling second
hand activities and all those functions are to be included in the information system.
The information management system that is to be developed for the organization will includes
human computer interaction that is the design of the system will mainly focus on computer
technology and to establish a relation between computer and humans. With the implementation
of Human computer system, it can be stated that the system will not only be limited to desktop. It
will include mobiles and tablets. A detailed discussion is provided to you explaining HCI and
UCD in developing this system and the implication of UCD in the system.
The HCI includes a broad field that overlaps the areas including the user centred design (UCD)
and design related to user experience. With the HCI and the UX design, the practitioners mainly
focuses on the academic that include scientific research as well as develop understanding related
to users.
The UCD that is included for designing the software is an iterative process that helps the
designers to mainly focus on all the users and the needs of the users in each design phase. The
UCD mainly includes involving the users in designing the design process and includes different
research in the system. The design techniques in UCD are highly usable as well as includes
accessible product for the users. With the UCD, the developers or the designers include a mix
investigation process and a generative method and different tools for understanding the needs of
the user.
The user centred design involved in for developing the software is considered as an iterative
process which helps designers to focus mainly on the needs of user and the focus of user. The

14SYSTEM ANALYSIS AND DESIGN
user design mainly involves including the user to design the process as well as include many
different research in system. The techniques of design are included in the process of UCD and
are highly usable and includes many accessible product s for all users. Along with UCD,
developers and the designers mainly includes some mix investigation process as well as
generative method to understand the need of the user and include different tools that are to be
included in the system design.
As the user of the information system will be management system of OZES, the associated
brokers, purchasing customers and the selling customer, interview and surveys are to be carried
out with the users of the system. The UCD includes four phases, understanding the context of
use, specifying the user requirements, designing the solutions and evaluating the requirements
that are included in the system.
The implications that UCD has in developing the system are:
 Helps to specify the context use for the system;
 Specifies the business requirements;
 Create a unique solution design for the system;
 Evaluate the designs;
 Implements the designs; and
 Finally deploys the design in the business operations.
There is a need to carry out UCD and the HCI for developing the system as because the above
stated reasons.
