Explain How A Business User Could Be Involved In The Core Activities Of Building An Information System

1a. The phases that Jeannine skipped are 1. The systems analysis and requirements phase 2. The systems design phase 3. The implementation phase and 4. Operations and Maintenance phase (Systems support and security).

For decades many information technology systems have failed to deliver the benefits expected by the users of the System. Insufficient user involvement in the design process is mentioned as a main factor contributing to this underperformance between what was expected of the system and what the system is in reality. They are so many System development methodologies but almost all approaches to system design / development involve users in the design process. The difference between the several approaches in system design lies in the degree to which users are able to influence the system design, “e.g., with SSADM, Learmouth and Burchett, Structured Data Analysis, users ,etc. are involved as providers of information to the project team since

What errors or problems will the new system have? The third stage is component design. For component design, we have to design the database and determine hardware specifications. The fourth stage is implementation. During this stage you have to build system components and conduct tests to see if it works properly.

The development phase is where the system is brought to life. In this phase, developers will build the system based on the models that were developed in the design phase. This phase is usually one of the longest on the whole process as it is when the actual creation takes part. If instead of developing the system, the practice is going to adopt one that is already developed, managers will seat with their counterparts from the systems to be adopted to discuss important aspects and details of the deal.

Over the early ages of computers, speed of computers is literally getting faster and faster every day. System development methodologies have been constantly developing referable to changing technologies and new demands from the varied range of user communities. In fact, system development methodologies plays a widely major role in the corporate, industrial systematic world and are continuously used in developing and improving information systems and software. Baugh (1990) clarified that since the system development methodology is related to a standard of steps named to a system development methodology, analysis, formulated by the organization and directed to arise and back up their information. The establishment of a system development methodology should be added to a developer of system analysis and design of a computer-based information. Software development life cycle is a methodology for designing,

2. Project Management: An information systems project can only be successful with intense interaction amongst project manger, system analyst, system designers and the end users (Philip,

Those steps are typical cycle of developing system methodology. For the steps to complete a cycle, it needs 3. Firstly, find out the mission, risks, and solution of design and limitations. Next, base on the target and limits to produce solutions. Lastly, this step will be let multiple persons evaluating the solution created by the developers and plan for another iterative phase, cycle. The cycle will repeat with simulate steps until the system exactly complete. Every cycle of it begins with some

Stage 1: The problem situation: unstructured. At this stage, the system practitioner recognizes that the situation is unstructured and is not clear to anyone, and that there are so many relationships included. So systems practitioner is going to find ways to explore and attend these relationships alongside the overall situation by looking at it holistically and taking the initiative to understand everything in, and anything that might lead to the situation. It can be achieved

Once this process has been given the approval of everyone involved in the project the system analysis stage begins. This is where the analyst analyses the problem the business is facing with a computer system. They will analysis the old system with the problems and find out the requirements for the new system. In the end the analyst will have the deliverable which is a set of system requirements for the new system.

Process analysis is the systematic breakdown of the phases of a process. The first piece of the process is the initiation phase, where the business identified a problem in the human resources (HR) system. A proposal to develop software for the real-time integration of the HR system with multiple other systems of record was submitted to solve the problem. After the business approves the proposal, the next part of the process is system concept development. This phase of the software development life cycle (SDLC) involves collecting system boundary documentation that identifies the scope of the system, conducting a feasibility study and cost/benefit analysis, and developing a risk management plan (Blaha & Rumbaugh, 2005).

In this cycle, the main aim is to test the application by applying different testing procedures in all possible ways. Preparation of test cases document which includes all the requirements mentioned in the release requirement document prepared by Business Analyst (BA). Executing of test cases checklist, which includes the main functionality of the application.

In the system documentation phase there will be a number of detailed records compiled. The eight phases of the project life cycle will be recorded in the system documentation category. The records derived from the system analysis and the system design phase of the project will be critical during the installation of the project. This will provide a detailed design of the project during the implementation stage. During the test phase of the project it is also important to document all test specifications and procedures. The test report will be

The Third phase of the development life cycle involves the design. This step involves defining the hardware and software architecture, specifying performance and security parameters, designing data storage containers and constraints, choosing the IDE and programming

At the Trinidad Gas Company (TGC), software development is done using an adaptive version of the Waterfall Methodology and the US Department of Justice Systems Development Life Cycle. The stages used by TGC in this mainly Waterfall Method involves the Initiation Phase, System Concept Development Phase, Planning Phase, Requirements Analysis Phase, Design Phase, Development Phase, Integration and Test Phase, Implementation Phase and Operations and Maintenance Phase. This methodology is a predictable, rigid and sequential design process, which means, that as each of the nine stages are completed, the developers move on to the next stage. In this sequential process there also exists a stage gate between each stage. This stage gate is simply a review of the project status to determine if to proceed or not. However, the stage gate approach is not always followed on many of the development projects undertaken by TGC. A brief description of each stage is mentioned below:

Utilizing the business approach to the solution allows the company to optimize the benefits. Initially, the software utilized for the administrative needs and scheduling will only be minimally tailored. Namely, this will entail taking advantage of the unique domain and customization of the portal. As the company expands, the technological solutions will be adjusted and designed in such a way as to fit organizational and individual needs. Revisiting the technology will be a major portion of the business process management A+ Tutuoring will subscribe to as outlines below. This is an important process requiring consideration of each aspect of the business and ensuring the current technology meets the needs of the company.
