Executive summary
OZES management team includes the management of OZES which have the electric supply a
young business and this distributes the electric equipment in Australia. This OZES have the
normal employees which are called as broker the duties of the broker is to sell and buy
equipment which is based on electrical only as this OZES is based on electrical supplies’
only. Here the platform for buying and selling of the electrical equipment is the online
platform and the website they are using is the Gumtree and eBay and the site which wants to
be selected is done by the broker so that they can increase the sale of the electrical item.
There is a broker who stores the data in the form of database, manual file record or through a
spreadsheet. The broker has the data to which there are competitive advantages to OZES.
Now here the profit is around 20%-40% which is less, therefore, the organization is planning
for hiring the full-time broker so that they can give the base salary to the broker and the profit
of the sold item, the profit which was given to broker will be 2.5% of the profit. For the rapid
growth, there is the ability to analyse the data for gaining the benefit for the sale. Here there
are second-hand electrical equipment sales so that the profit will be more. Here for
promotion, the broker placed the advertisement to which customer will respond or will
approach the broker. There is broker ID gives that the organization will have profit will be
share to the broker who actually owns it. OZES needs information which is stored in the
details of the customers. In this, the detail includes the email, phone number, address or name
of the customer. The customer will fill the broker id or the broker name from which he has
come to purchase the items. When the items are deposit to the OZES then it is checked
completely that it is working properly or not once the item is checked then the item is logged
off and then finally it will be placed in the storage of the OZES. There will be two staff
present in the store one will pack and the other will be sent the item. The item is tracked until
the item will receive by the customer. There is a broker who stores the data in the form of
database, manual file record or through a spreadsheet. Here there are second-hand electrical
equipment sales so that the profit will be more. Here for promotion, the broker placed the
advertisement to which customer will respond or will approach the broker. This is the
summery for the OZES management that what the thing is going to have in this. Here there is
a description of the things which will go to happen and this includes the management of
OZES. There is notification is send through email so that the broker can see that the item is
delivered to the customer or not.

Introduction
In this, there is OZES which is the organization of the electrical and in this, there is a need to
manage the OZES the electric supply a young business and this distributes the electric
equipment in Australia. The platform for buying and selling of the electrical equipment is the
online platform and the website they are using is the Gumtree and eBay. The broker placed
the advertisement to which the customer will respond or will approach the broker. There is
the system built to manage the OZES which is shown through the use case diagram, UML
diagram and this all were implemented through the Draw.io software which is online
software and easy to use and make. The diagram shows the system designs in a very simple
way so that it would be understood by all.

1. Consultation
To build any types system there is need to have the software development process which
involves the SDLC that means planning phase, the requirement of resources, design the
project, implementation of the project, testing of project and maintenance of the project.
There are different models mainly waterfall model, spiral model, prototype model, agile
model, an iterative model (Özge, 2019).
Agile Model
This model believes that each project needs to have the existing methods and to handled
differently. Here is an agile model, there are small frames which consist of large but the agile
work on the small frames only.
There are principles which are followed in the agile model:
1. Interaction and Individuals: In the Agile model, the development is for the motivation,
self-organization and have the interaction like co-location.
2. Working software: There is a demo for the software which means strong communication
between the factors of the project. There is a requirement of the documentation of the
working software.
3. Customer collaboration: The project involves the customer until the phase of design which
is used to approve by the customer so that there can be the product made just by the needs of
the customer.
4. Responding to change: There is a quick response to continue and change the development
(Blake,2019).
Advantages of Agile
1. The software which is made is the real-time and the approach which will be used to build
the software is realistic.
2. This give rises to teamwork and cross-training.
3. The partial work delivers to the solution and the software is partially working.

4. The good model changes the environment steadily.
5. Documentation and minimal rules are employed.
6. The requirement of resources is minimal.
7. The functionality is shown rapidly and demonstrated to the products.
8. The management of the model is very little.
9. Little planning is required sometimes but without planning also the phase can be
completed.
10. The development is concurrent which have the delivery of the planned text (Gong,2019).
Disadvantages of Agile
1. Complex dependencies of the products.
2. Risk can occur which is maintainability, sustainability, and extensibility.
3. There is costumer dependence so that the project might get stop in between.
4. There are individual dependencies which have less number of documents.
5. Transfer of new teams into the new technologies which have quite challenge.
6. The team direction might get wrong.
Iterative Model
This is also the part of SDLC which have the process to start the simple implementation
which has small sets of the software requirement. The complete system is implemented just
part and there are small frames which consist of large but the agile work on the small frames
only. The reviewer of the software is the development which identifies further requirement
which repeats the process (Özge, 2019).
Application of Iterative Model
1. There is a time to which the market may constraint.

2. It is different and new technologies are built to bring and learned the development of the
team which has the working in the software project.
3. There is a risk of high feature ad the goals may change for the future.
4. The requirement is defined and there is a request which is an enhancement to evolve the
time.
There are advantages of the iterative model
1. The result is got early and periodically which have to enter in the project.
2. There is measured which can be progressed.
3. The parallel development which can be planned to develop the software and this helps to
make the project to develop it very quickly.
4. The cost required to achieve the scope of the project.
5. The testing and debugging are very simple and easy of the iterative model.
6. Risk is analyzed to resolve and have each phase of the iterative.
7. Risk analysis is better.
8. The functionality is shown rapidly and demonstrated to the products.
9. This give rises to teamwork and cross-training.
10. The development is concurrent which have the delivery of the planned text.
There are disadvantages to the iterative model.
1. May require m more amount of resources.
2. There are individual dependencies which have less number of documents.
3. For risk management, there is highly skilled resources are required.
4. The project might able to know the risk.
5. Risk can occur which is maintainability, sustainability, and extensibility.
6. Transfer of new teams into the new technologies which have quite challenge.

7. This small project not suitable (Blake,2019).
The methodology of Iterative and Agile
Table 1: Methodology
Iterative Agile
Task analysis is based on the discovery of
the previous task and improves it here.
They do not have lightweight which can be
used with the help of engineers. Scrum has
the popularity of the SDLC model that
they have a high rate of production.
Scrum this is the management of the
framework which has abilities to control the
iteration and incremental of all the type of
project. They are basically lightweight which
can be used with the help of engineers.
Scrum has the popularity of the SDLC model
that they have a high rate of production. This
includes two phases Lean and Kanban
method.
Extreme programming does support by
iterative but it is not a highly disciplined
method which has the delivery of software
with the high quality. This does support
simplicity, Communication, feedback, and
Courage. The customer is involved in the
close-knit.
Extreme Programming this is of XP which
have a highly disciplined method which has
the delivery of software with the high quality.
Here the customer is involved in the close-kit
which have to perform the testing of the
software, planning of the software, etc. This
support simplicity, Communication,
feedback, and Courage.
This does not have the lightweight
software which has the adaptability with
the methods.
Crystal in this methodology this is
lightweight and have the adaptable of the
development software which has a
lightweight and this includes the Clear,
Crystal Yellow, Orange Crystal Orange.
This is a static system for developing met. DSDM this stands for Dynamic System
Development Method which provides for a
framework for project delivery which is RAD
and this is unstructured data.

2. Use Case diagram
This is the relationship diagram which helps to interact with the system and user and this
basically helps to tell about the system. The use case helps the person to see the connectivity
of the functionalities of the system. This helps to identify the organization and clarify. This

consist of the possible sequence of the environment which have related goals with a group of
elements (Dhir,2019).

Description Here the organization sells the second had an
electrical item which is done with the help of
a broker which takes the second-hand

manager. Here there is an online business is
done which consist of sale the product and
make the online business.
Class Diagram
There is the static diagram which helps the developer to develop the design according to the
system designs. This describes the attributes of the class and operation which imposed on the
system. This analysis and designs the static view of the application. There is responsibilities
system which describes the system. This is deployment and component which have the
diagrams. This help to collaborate with the elements of view (Dhir,2019).

Appendix
Here at present, there are not all the system good system present for working of the
application, therefore, there is the demand for the new User-centered design for the human
interaction. This design is an iterative design which focuses on the designs and the user that
how the user will free to use these designs. To build the user designs there is some phase
which has to be followed so that there can be a good design and this will help for the
interaction for the user.
This includes the investigative which involve the surveys and interview and the generative
which involve the brainstorming to develop the understanding tool.
The phases which involve building the UCD are
1. Understand the use of the context
2 Specify the user requirements
3. Design solutions
4. Evaluate the requirements for the project.
This helps for the infraction to the system and users.
There are six principles to which UCD work for the HCI
1. Goals setting for the business: this helps to determine the target of the project like here the
target is to develop the human-computer iterative.
