Systems Analysis And Design Paper

As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary (Dennis, Wixom,

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,

Managing the development of major software systems and estimating the cost of that development have always been difficult, but they can be especially challenging in dynamic and continuously evolving government environments. At the same time, advances in computer power, computational analysis, and engineering methodologies are transforming the way new systems are developed.

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)

“A process model is a graphical way of representing how a business system should operate. It illustrates the processes or activities that are performed and how data move among them. A process model can be used to document the current system (i.e., as-is system) or the new system being developed (i.e., to-be system), whether computerized or not” (Dennis, Wixom, & Roth, 2012, Chapter 5).

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.

System analysis is a problem solving approach that decomposes a system into its component pieces for the purpose of studying how well those component pieces function to accomplish their purpose. System analysis can be broken down to five approaches which include Model-Driven Analysis, Accelerated System Analysis Approach, Requirement Discovery Approach Methods, Business Process Redesign and Fast System Analysis. In this report, approaches and techniques that are used to make System Analysis possible are discussed.

The detailed look into process analysis has been vital to understanding the organization of a particular subject. Some of basics I have learned from the study of process analysis are: to recognize the desired product of the process analysis; to put together a thesis that clarifies my attitude towards the process; keeping the audience in mind; utilizing basic prewriting to identify the best route to take in organization; identifying the directional and informational aspects of process analysis; explaining the process one step at a time; making it easy for the readers to follow the sequence of the analysis; establishing the right tone throughout the process; and, how to open and close the process analysis effectively. My experiences learned from process analysis is the recognition of how important

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.

As part of my job in Business Systems ‘Analysis LTD (BSAL), I have been requested to create a report which enables businesses and the general public, to understand what systems analysis is and why it is a value to businesses. This report will clearly illustrate the principals of a systems analysis which are used to identify the system which a business has in place, issues which are related to the system and a solution for the issue. Doing this using a structured analysis has many benefits and will make the whole process much easier and reliable. There are different systems development lifecycles which can be used to create or solve issues of a system. Each stage of the systems development lifecycle will be explained along with all the different alternative models which are available. Businesses require a system analysis due to key drivers. Key

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.

Project management is a series of steps taken in sequence to manage a project through all phases from conception to completion. The steps are documented in a strategic plan. The plan is used to ensure that all parties are working towards a common goal. Project management requires applying knowledge, skills, tools and techniques to specific activities in accordance with established standards and guidelines. There are five basic functions of project management: planning, organizing, staffing, directing, and controlling. Basic activities of project management include: identifying project requirements to define the outcomes; addressing various needs, concerns and expectations of others; setting up, maintaining and carrying out communications; managing others; creating project deliverables; and balancing competing project constraints.

According to Kerzner (2004), project management is the planning organizing directing, controlling of company resources for a relatively short-term objective that has been established to complete specific goals and objectives.

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).

The systems development process can follow any number of methods, tools, and approaches and is not tied down to any specific one. Although there are some conventions, changes and additions can be arbitrarily adapted to suit the customized process.
