Intro to System Analysis and Design

In this class, we’ve stressed the importance of various system analysis and design tools and techniques. By now you should have a “toolbox” full of useful design and analysis tools. List the tools in your toolbox and then write one short paragraph on how you can/will apply them in your careers, lives,

A system is an organized structure that has inputs and outputs that carry out a specific activity. A system is a group of components that makes up a complex functioning unit. When an element changes, the system will stop functioning right. Once the system has been defined by jurisdiction, budget, coverage requirements and user needs, the next step is to design the system using components and systems that are obtainable and have the desired features that the customer and the design engineer have agreed upon. If the design engineer is not careful, then there will be coverage, operational, maintenance and reliability issues that will plague the system forever. The equipment-engineering phase will specify each and every component in the system, (Wiesenfeld, 2010). Due to a problem or situation, there is a beginning and an end to a system that is tasked to solve that problem.

Systems analysis is when business hire individuals to analyse their systems to determine what issues are present with their current systems and provide a solution that will fix the issues.

The next step in the process is system analysis. This second stage involves gathering requirements, such as documenting the strengths and weaknesses of the current system, having discussions with the users to understand their roles and needs. This is an integral part of the life cycle as employees are the most important asset a company has. Baya, Gruman, & Mathaisel state, “information technology

They may also devise ways to apply existing systems’ resources to additional tasks. Most systems analysts work with specific types of computer systems- for example, business, accounting or financial systems or scientific and engineering systems –that vary with the kind of organization.” (Computer Systems Analysts, 1)

In this self-starting world, system analysis and design are generally connected with the actions of software development. Systems analysis and systems design are normally theorized as the two main components of a system development. System analysis is the course of exploring a system, detecting problems, supporting the details of a present or planed system, which uses the information to encourage advancements to the system. in the organization which I am employed, there are numerous

* Systems analysis would assist in understanding their existing system and identify problems which would help to improve the system.

The Project Manager will develop the preliminary budget and timeline based on the detailed project plan. Due to the uncertainties involved with estimating project requirements, management should build flexibility into the schedule. The Project Sponsor will evaluate the analysis results before formally approving the project plan, budget and timeline.

b. What will the new system accomplish? What functions will it perform? Which organization goals will it support?

System Analysis is the study where detailed information about the components and requirements of a system, the information needs of an organisation, the characteristics and current components of the systems and the user functional requirements of the systems that is proposed system.

Here I want to discuss what is System analysis and design, when and where the concepts are used and how to overcome the problems using these concepts. The methodology of using characterizing the parts, structural engineering, interfaces and information for a framework to fulfil the decided necessities is said as system design. This course is helpful in developing the designing and analysing skills. Overall, system analysis and design is said as analysing and designing the different process.

System development can generally be thought of having two major components: systems analysis and systems design. In System Analysis more emphasis is given to understanding the details of an existing system or a proposed one and then deciding whether the proposed system is desirable or not and whether the existing system needs improvements. Thus, system analysis is the process of investigating a system, identifying problems, and using the information to recommend improvements to the system. System design is the process of planning a new business system or one to replace or complement an existing system.

Systems analysis refers to a problem solving technique where a business or procedure is studied and the goals are identified in order to create information systems to help the business achieve their goal more efficiently and easier. Systems analysts obtain feedback from the system users in various ways e.g. interviews, questionnaires etc. More importantly they find out from the users what their specific requirements are regarding the proposed system and then use the information obtained to formulate requirements for the system, the system is then written ensuring that all the requirements and expectations are met.

System engineering is an involvement or combination of more than one discipline to achieve customer requirements within constraints. It develops a system which solve complex engineering problem with the contributions of different discipline perspective and produce the optimal solution in order to meet the requirements. System engineering prioritize in the customer needs and acquire functionality early in the development process[4]. It then proceeds into the design phase and validate the system as a whole complete problem[4]. System engineering incorporate all discipline and turn them into a group effort and goes from a concept to production to operation[4]. System engineering is important in a complex problem because it able to turn an initial idea into a fully descriptive system with all the essential elements integrated into a complete whole system[2]. These can then serve as a basis of decision making. In other words, it serve as a starting point to solve a complex engineering problem. It can also helps to maintain project going in the right direction in an orderly manner. Moreover, system engineering able to minimize error in a project because it considers every aspect that might affect the project and evaluate it as a whole. The term was first seen in 1940s back in the Bell Telephone Laboratories[1]. It is difficult to determine the exact origin of system engineering but many agree that it was introduce after World War II[3]. During this time both the race

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
