ISYS225 SYSTEMS ANALYSIS AND DESIGN
Reflective journal
It could be considered that the main goals of the system analysis and design has been
the improvement of the organisational systems. Frequently this kind of procedure includes
the development or even acquisition of the application software and then training the
employees for using the software efficiently (Azar and Vaidyanathan 2015). The application
software, commonly referred as the system is mainly designed for supporting any particular
process or function of the organisation like the inventory management, market analysis or the
payroll. The main goal of the application is turning the data into effective information. For
instance, the software that is created for any inventory division at the bookstore might
preserve the track of accurate amount of the books in inventory division at any bookstore
might preserve the track of the number of the books included in the stock of newest best
seller. The software that is primarily designed for payroll department might help in keeping
the track of altering pay rates of the employees (Dennis, Wixom and Roth 2018). It could be
considered that the range of the off-the-shelf application software could be easily procured.
Moreover, the off-the-shelf software might not fit all the requirements of any specific
organisation and therefore, it is required for the organisation to develop their own product
(Pedrycz 2016). It could be considered that the aspect of the system analysis and design is
active and exciting sector where the analysts constantly learn the new techniques as well as
the approaches for developing the systems increasingly efficiently and effectively. Moreover,
presently there are a central set of required skills for understanding that no matter the tactic or
the methodology utilised, the software is effectively developed and it works as intended. All
the projects of information systems travels through the four stages of the design, planning,
analysis as well as the implementation, the projects needs analysts to collect the
requirements, efficiently model the requirements of the business plus creating the blueprints
for process by which the development of the system would be done and all the projects needs

the proper understanding of the behaviour of the organisation concepts such as the team
building and the change management (Balanis 2016).
It could be analysed that the major goal of system analysis and design is the
improvement of organisation systems. Information system analysis and design has been
growing as the presently the most popular method that is used by the companies for creating
and then maintain the information systems that performs the fundamental business
functionalities like processing the orders, maintaining the track of the customer names plus
the addresses as well as paying the employees (Gupta 2017). The most common method of
system analysis and design is the object oriented designing. The procedure of the object
oriented design is mainly the extension of the procedure of the object oriented analysis except
one crucial aspect, the consideration and the implementation of the constraints. The object
oriented analysis and design has been considered as the technical method that is used for the
analysis and design used in any system or application using the proper application of the
concepts and hypothesis of object oriented approach that includes the visual modelling
(Gonen 2015). This particular approach is mainly applied all through development life cycle
of the application or system with the intention of fostering the improved product value and
also reassuring the participation of the stakeholder and the communication.
In present times, the software and the computer application system are significantly
complicated concepts as there are significantly few material limitations and lot of the possible
arbitrary reconstructions (Giurgiutiu and Lyshevski 2016). It could be analysed that the
software does not enjoy any kind of restrictions and there is required minimal room for the
complexity for growing large. This is the aspect where the object oriented analysis and design
is introduced. It utilises the abstraction as the tool for encapsulating the complexity and with
introduction of the increased abstractions, the greater is reduction of the complexity. These
particular acts of the encapsulation and the abstractions permits for the specific issues to be
