SYSTEM ANALYSIS AND DESIGN2
Part A: Essay
Question 1: Essay
a) Core Processes: There are six core processes that are included in the process of life
cycle of SDLC. The main processes of SDLC life cycle process are planning phase, designing
phase, developing phase and implementing phase, testing phase and deploying phase, and lastly
the SDLC maintenance phase (Stark 2015). All the different processes are to be considered for
developing the IS system of YITSC. The core processes needed for developing the information
system are explained below:
1. Planning phase: In the planning phase, proper plans for developing the project is to be
confirmed. Without having proper plan for project development, the strengths of the project
cannot be defined as well as weakness of the project is also not stated for the project. Not doing
proper planning of project, the project becomes meaningless and there should be proper project
planning in the project. Planning of the project helps in project kick off smoothly and provides a
rough idea about the project that is being carried out in developing the project.
2. Analysis Phase: In the analysis phase, the performance of the project is to be analysed
along with different software that are carried out in the different stages of the project (Artto,
Ahola and Vartiainen 2016). The analysis phase states all additional requirements that are
included in the system. For proceeding in the next step, analysis for developing the system is
important.
3. Design phase: After completion of the design phase, it is important to implement the
design phase of the system. The design phase includes building the project architecture. The
design phase includes developing the software without any flaws which is done by setting

standard as well as attempting all the standards that are included for developing the YITSC
controller system.
4. Development and Implementation: The main task to develop a software actually starts
in the development phase. The software is being implemented as well as developed in the
developing phase and all the data that are recorded for software development are utilized in the
development phase. After the building of the software, the implementation stage is carried out
where it is seen that the product is properly functioning and all the studies related with the
product is implemented in the implementation phase.
5. Testing Phase: In the testing phase, the application system of controller is tested
against errors as well as states if there is document bugs in the system. If so, the system
developer reduces the bugs and fixes that the software of Controller work properly for YITSC.
6. Maintenance Phase: The maintenance phase is the last process that is carried out in the
SDLC process of software development. After the software is passed through the testing phase
and all testing is completed, the software or the application system needs to be maintained.
System maintenance would help to maintain the system and provide security to the system. If
there are any issue in the maintenance process, the system is to be fixed and is to be upgraded
from time to time with the advancement of technology.
Activities of Core processes: Activities that are performed in each of the processes of
SDLC method are stated below:
1. All the problems in the current application or system is to be identified first before
starting the development of application (Butterfield et al. 2016). This activity includes getting
input of all the stakeholders that includes the customers, the industry experts, the programmers
