2SYSTEM ANALYSIS AND DESIGN
Part A: Essay and Memo
Question 1: Essay
School Supplies Pty LTD is based on Brisbane which aims to supply a large number
of stationary products to various business clients (Liu et al. 2018). The busiest time of school
supplies is considered to be era of providing back to school and stationary packs to various
schools and parents. In 2012, the school supplies were bought out by businessman and ex-
principal Gerry Lane. Adaptive software development comes up with ability for
accommodating changes. It is adaptable environment with various kind of product with
comes with little planning and proper learning. Adaptive software development is considered
to be evolution model with reflection in the complex system. There are mainly three phases in
adaptive development life cycle that is speculate, collaborate and lastly learn.
Scrum approach is considered to be best one for managing the development of the
system process (Rautaray and Agrawal 2015). It can be stated like an empirical research
which is needed for applying various kind of industrial application protocol. It generally does
not define any particular kind of software development which is needed for development of
the software. Scrum focus on the fact that how the team members should function so that they
can easily provide flexibility in the rapidly changing environment. The main goal of Scrum
methodology is the development of various environmental and technical areas. This will
ultimately make the whole development process for easily responding to changes. Scrum is
very much helpful in improving the present engineering method. Scrum master can be
defined as a new kind of management role which has been introduced by Scrum.
Extreme programing has developed due to large number of problems by the help of
long development lifecycles. The lifecycle of XP comprises of mainly five phases that is
Exploration, planning, release and lastly maintenance (Lazar, Feng and Hochheiser 2017).

3SYSTEM ANALYSIS AND DESIGN
There are large number of roles and responsibilities are there in XP for various kinds of task
and purpose. XP generally aims to provide some of the successful kind of software
development which has a changing requirement in small and medium teams. Short iteration is
considered to be some of the release which comes up with rapid feedback and customer
integration and lastly testing. XP has been designed for small and medium size organization
(Gold and Vassell 2015). It is applied when the size of the team is limited between three to
twenty project members. Communication and coordination between the members of project
should be enabled in the given time.
FDD stands for feature driven development is considered to be an agile methodology
which is used in development system (Kardaris et al. 2016). FDD comprises of five process
which tends to provide certain number of methods and techniques. It is needed for
understanding various aspects various aspect like roles, timeliness which is needed for
project. Unlike some of the FDD methodologies which is needed for development of the
critical system (Kniberg 2015). The FDD approach comprises of certain number of approach
which is needed for the effective industry. It focusses on certain number of quality by the
help of process which is accurate for the progress of the project.

Sub: Providing various ways for design of Human Computer Interface for this Online
Ordering system.

4SYSTEM ANALYSIS AND DESIGN
School service was bought by businessman and ex school principal that is Gerry Lane in
the year 2012. With the passage of time quality range of educational supplies and various
good services for Gerry. A big business earner comes up with school supplies which is the
annual method of back to school process. It comes up with more than 4500 school which is
ordered, delivered and received by various school children. The whole process of ordering
starts with BTS pack start with various parents placing the order. It can be done over the
phone or online platform. In the recent times the school contracts are wining more
contracts because of their reputation. It comes up with the ability to deliver to proper items
at current time. A large number of methods can be used for understanding the technique of
human computer interaction for this online ordering system. Major methodologies focus on
certain number of model which emphasize on certain number of points like user, technical
system and lastly design. The activity theory is used in various human interaction with
takes place with system. Activity theory emphasize on certain number of theory which can
be used for analytical tools which is provided in the given format. The design of this online
ordering system should be user centered in nature. User center design is known to be a
modern platform which is used by users that makes use of design of any computer system.
Various aspects like user, design work up together for understanding the need and
limitation of the user. It creates a large number of system which checks these elements.
There are seven principles of user interface design which must be taken into consideration
at the various design of the user interface. It is needed for various aspects like simplicity,
consistency and structure. Value sensitive design (VSD) is a well-known method which is
needed for building technology which works for the people. It makes use of technology
which affect the people in both direct and indirect way. VSD make use of iterative design
method which requires three types of investigation that is conceptual, empirical and lastly

technical. Conceptual investigation emphasizes on understanding the need of various
stakeholders and technology. The ultimate conflict takes place when the stakeholder makes
use of various technology. The human computer interface has been designed in such a way
that it can easily act at the point of communication. The flow of information takes place
between computer and human can be stated like loop of interaction. The loop of interaction
comes up with various aspects like visual based, audio based and machine environment.
Visual based human computer interaction is considered to be large area or domain which
needs to be researched in a proper way.
