Systems Development Methodologies ( Quarban Ali ) Essay

The management of a consulting project calls on a variety of skills. This is an actuality that has been stressed throughout the course lectures, seminars and cases as well as throughout the course literature. The fact that consultants must integrate their skills when conducting a consulting project is as clear-cut as it is evident.

In order for any organization to be successful, they must find effective ways to change systems and policies that are ineffective in creating a successful environment. A system consists of four things, elements, attributes, internal relationships, and the system environment. The systems theory is transdisciplinary study of the abstract organization of phenomena, independent of their substance, type, or spatial or temporal scale of existence (Heylighen & Joslyn, 1992). The study investigates all the principals common to all complex bodies, and the models which can be used to describe them. Von Bertalanffy (1971) was the creator of the “system” concept, he developed this idea as an answer to the limitations of individual disciplines in addressing complex social issues (Mitchell, 2005). The underlining principal of this theory is that an organization consists of multiple, interdependent parts that collectively form more than the sum of their parts. Developed from the systems theory, are three separate theories with the basis of each being the systems theory. The activity theory considers the entire program versus just one single sector, it sees the operation as a whole instead of sub departments, it combines both micro and macro elements of the organization. The chaos theory does not mean a chaotic hectic situation, rather a situation where there appears to be little to no order, there really is a hidden underlying order. The complexity theory is

When developing a new information technology system such as a health documentation system, a team will work through a series of steps “in order to conceptualize, analyze, design, construct and implement a new information technology system”. (Morris, 2009). Traditionally, there were five phases to developing a new system, but it has been found that having seven phases can provide analysts and developers create a system that can more precisely meet the needs of a company. The stages include: planning, systems analysis, systems design, development, testing, implementation and

Another way of successfully gathering information is by building a prototype or model of the system, so that users can test or get an idea of what the finished product will be like. With this they can determine issues, problems, or inconsistency with the system. Another important part of gathering information is organizing it so that it can be understood and put to proper use. I propose categorizing the requirements into functional requirements, operational requirements, technical requirements, and transitional requirements. The functional requirements define how the user thinks the system is functioning overall, the operational requirements define what background processes need to be executed in order for the system to work optimally over a period of time, the technical requirements define what technical issues that must be addressed in order to successfully implement the system, and the transitional requirements define the processes or steps needed to implement the system smoothly and successfully. ("Mind Tools", 2012).

This way the IT department can understand what the higher level and lower level employees need for system stability and a better graphical interface. Another plan of action would include the method of Systems Development Life Cycle or SDLC. The phases of this method are planning, analysis, system design, implementation and operation. First we must plan on what exactly we are trying to accomplish. We know we need to upgrade the Riordan Manufacturing system. Next we must analyze the system and look for problematic errors. A project proposal can be essential to launching a system analysis (Farah, 2013). These are things to keep in mind: understand the business situation or problem, understand the significance to the problem in the organization, think of alternate solutions, the use of computer information systems for solutions, find people interested in the solving the problem (Farah, 2013). This plan is used to decrease redundancies, errors, and increase security. Finding all the weak spots in the company will help in the improvement of integrating an updated efficiently functioning system. Feasibility is important to account for when upgrading the system. Integrating a CRM will help to work with customers and understand their needs and wants to benefit the company and the relationship with their customers. Designing the system will involve knowing what kind of software is needed to store and

The information system’s requirements in the systems planning phase are based on a case summary, potential interview questions, and the systems analyst’s experience in systems planning. One must not only generate requirements based specifically on what users’ state they want or need. Analysts must also generate requirements based on insight into the overall organization and project goals.

Technology is changing rapidly and because of rapid change in the technology, works are being done instantly. However, in Reef Adventures, because of the manual handling of the works and only one system in the office; which takes takes lot of time to finalize the works. Particular problem area is included in the hazardous, paper based system; duplicate and mishandling of records which has resulted in frequent customer complain. The aim of this project is to plan the information system for Reef Adventures, in which work becomes faster with accurate information and without duplicate records. This report presents the design and analysis of the

Discuss the system development methodology used? If information systems are acquired from off-the-shelf products, what is the process of procurement that is used in the organisation?

In corporate America projects are implemented on a regular basis. With implementing these projects there is a grave possibility that they may not be successful. In conducting any successful project it takes some type of organizational skills. Successfulness of a project can be jeopardized by a lack of planning, not enough funds to complete it, or the materials needed to complete it may not be readily available. In order for a project to be a success everything about the business must be evaluated to understand how well the system works. This paper will which information gathering methods can be used in analyzing the requirements, classifying which business

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.

Consumer and Industrial Products, Inc manufacture a variety of different products for individuals and businesses. Due to ineffective accounts payable system, Consumer and Industrial Products, Inc started a new project called Payables Audit Systems (PAS). The process of beginning this new project was taken very seriously. Roles were assigned and defined. Ted Anderson was the director of the project. Peter Shaw was assigned the responsibility of user project manager. The user project manager was “responsible for making sure that the system meets the user department’s

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.

Great Education Books is a local Nelson business which sells textbooks and other educational books to students attending local secondary schools and tertiary institutions. They currently sell these items using a small shop in town but have decided to move to only an online presence to reduce the cost to students. They have decided that the total price per item including a delivery charge will be less than having a shop in town.

Today, many project managers and organizational leaders grapple with the question, is the traditional Systems Development Life Cycle (SDLC) and the supporting Project Management Life Cycle (PMLC) processes relevant for todays projects? Depending on the level of completeness of the specifics known at the time the Requirements Breakdown Structure (RBS) is developed, a choice is needed to be made as to the appropriate approach to plan and manage the project. Hence, an agile approach could be the right solution. This writing assignment takes a close look at the considerations confronted by the Pizza Delivered Quickly (PDQ) business to help with the decisions needed to fulfill the PDQ application requirements and manage the project.

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).
