CHAPTER 4 SYSTEM ANALYSIS 4.1 INTRODUCTION System analysis involve the analyses of the whole module or part of the system. It is also deals with the behaviour of the module that is interaction between the internal and external environment. In this phase whole module is divided into sub module. Solve the each module separately then add the sub module. 4.1.1 System A system is an orderly group of interdependent components linked together according to a plan to achieve an exact goal. It's mainly uses are in company, between the user, depend on the other system, add all the system and achieve the goal. 4.1.2 System Analysis System analysis and design are the application of the system approach to problem solving generally using …show more content…
The phase and steps in making this determination is called feasibility Study. This type of study if a project can and should be taken. In the conduct of the system information, the analyst always inter relate the different type of the feasibility study to conclude the system analysis. 4.2.1 Technical Feasibility Software that will successful satisfy the user requirement the technical needs of the system may vary considerably but might include In a given time it will produce exact output. Produce well response time. Ability to process a certain column of transaction at a particular speed. 4.2.2 Economic Feasibility Economic analysis is the most frequently used technique for evaluating the effectiveness of a proposed system. More commonly known as cost / benefit analysis. There are several way to estimate the benefit and savings are expected form a proposed system and a compare them with costs. It benefits outweigh costs; a decision is taken to design and implement the …show more content…
System study is carried out in two phases, in the first phase we deal with understanding the scope of the system. Second phase seems to be more complex were we understand the end user requirements, limitations and problems of the existing system are studied. 4.3.2 FEASIBILITY STUDY Feasibility is the determination of whether or not a project is valuable or not. The phase and steps in making this determination is called feasibility Study. This type of study if a project can and should be taken. The analyst always inter relate the different type of the feasibility study to conclude the system analysis. 4.3.3 SYSTEM ANALYSIS System analysis involve the analyses of the whole module or part of the system. It is also deals with the behavior of the module that is interaction between the internal and external environment. Solve the each module separately then add the sub module. 4.3.4 SYSTEM DESIGN After analyse the requirements of each end user we need to be prepare system with
The two main issues in this case are the project analysis and financial forecasting. The project should be analyzed before doing the forecasting, because any recommendations on the project will affect financial forecasting for the next two years.
Stage 3 involves creating an Architectural Model version of the whole system including sub systems. A Viewpoint Hierarchy shows a skeleton version of the system which can be ins...
SAP is a leader when it comes to easy integration among all the departments. It provides industry specific solutions for different industries other than its basic SAP modules. A Module is a sub section of the ERP program. Many different modules can be purchased for business specific applications and industry specific solutions as well. Some of the most important sub modules in SAP are Finance, Controlling, Sales & Distribution, Material Management and Human resource. Depending upon the organization needs, a client can buy whatever modules needed.
It is a step of defining the goals of the projects and the results are aimed at reaching certain levels of productivity of customer satisfaction. The second stage is measure, and it is the stage of collecting data and facts and evaluating current operational performance. The third stage is analyze with the purpose of developing methods and theories that will best suit the solving of the problem; it is also a stage of detecting cause-and-effect ties of the processes. The fourth stage is improve, it is aimed at generating ideas for reaching the desired process improvement. Finally, there is the control stage that is about monitoring the operations to find out whether the process of improvement is smooth and the problems were solved (Meredith & Shafer,
For decision making purposes, the projects can be further divided into two groups which is independent project and mutually...
After the systems planning is complete, the next course of action is the systems analysis phase. This phase includes defining the requirements of the system. This means that the team must conclude what the system needs to do in order to satisfy the users. This is done by forming a requirements...
Multiview is an approach to system analysis and design and is accomplished by breaking view specification into independent tasks. It focuses on organisational goals and aims to further them by integrating the system in accordance to the people that work within the establishment.
The team implementing the new system were required to do both functional and systematic requirements thus affecting the implementation of the new system
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
The table below shows a sample specification that describes each subsystem in more detail. The
Timely completion of projects within the budget and scope satisfies the client’s expectation, which in turn determines the project success. (Anton de Wit, 1988) asserted that the project objectives set the most relevant criteria for success in projects. And stated that when all stakeholders are considered while formulating the project objectives, would not entirely depend on the time, cost and the quality of the project. The success can be considered only if the project satisfies these objectives. Along these lines, the success criteria are subjective and are controlled by the stakeholders more
The primary objective of system design is to analysis to thoroughly understand the organization’s informational needs or requirements to set the specifications (Satzinger, 2015). This system design is to structure the components of the final system, which serve to distributed the type of environment the user will do. When looking at application software components within the system design, the analysis needs to figure out the sub systems, and relationships to each part of the

To identify proposed projects that are not really projects and should be handled through other
As per area point of view, this concept is area specific. One project which have got immense success in one area need not to be succeed in another one. Thus it have to be adapted as per particular area’s problems and expectations of the people living therein.
