Development Processes And The Performance Of Successful Build And Maintain Information Systems

Another factor to ensure success is to train the IT personnel on the system’s applications and processes. How well the IT personnel understand the systems is extremely relevant to the success of system implementation. The involvement of IT personnel, who have knowledge regarding the application requirements, increases the ability of the team to correctly and quickly specify the requirements. Experienced IT personnel on a team help ensure others understand terminology and have more of an understanding of the stakeholders needs (Havelka and Lee, April 25, 2002).

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

One of the first steps involved in carrying out a preliminary investigation include understanding the problem or opportunity in sight. The analyst must first identify which department, users and business processes the system request is involved in to evaluate and assess the causes and effects related in the proposed system. Defining the project scope and constraints is the second step. With clear indications of the projects boundaries or extent the project scope is determined, while the requirements or conditions the system must confer to or achieve determine the projects constraints. The third step in a preliminary investigation consists of fact finding techniques, that involve the analyses of charts, interviews with users, managers and review of documents , observing operations and finally user surveys. Followed by the fourth step that includes the process of evaluating feasibility. This step consists of evaluating the feasibility of the proposed projects operational, technical, economical and

The system champion will be responsible for leading the team and that particular team will come together and determine the expectations of the project while creating a project plan. The assembled team must get a list together of goals needed to accomplish within the new system and access the way these goals are going to be accomplished. The goal of the information system is to process and store data while keeping information safe and secure for the organization and within this process the important goals need to be understood by all members of the team, and implemented within the system. There are surveys given to the implementation team, and staff members so that the goals are identified by the importance it holds and will play within the process. Once the goals are determined the team is ready to find a vendor who fits the requirements by creating a list of all vendors to send a request for a proposal to the chosen vendors. The only time an organization accepts a request from the chosen vendors is when and if they are willing to do a demonstration for the staff and team members on the site. This on-site demonstration will help the staff to have a better understanding of the system while making an informed decision based on the information presented. This demonstration will also help the implementation team decide which vendor produces the better system while meeting 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?

Big Corporations and Health care organization are always looking to improve their information systems to save time, money, and people lives. One most used information system would be the System Development Lifecycle (SDLC). A system development can sometimes run over budget or the corporation and organizations will never receive full satisfaction if their goals are not accomplish.

The measure of how an IT project impacts the practices of business regarding its strategy is the ultimate value. Effective business cases for business investments indicate the link between IT projects and the strategies of the companies that engage in the same(Wild, Wild, & Han, 2014). Some of the methods that can be used in this assessment by a firm include:

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

Every organization should implement information system to operate their business activities. This article describes how a punctuated process model can analyse a specific information system development (ISD). They also focus on information system project which was implemented in a UK retail small medium sized enterprise (SME). A new technology was being applied instead of previous one. Basically information system method can give us a new realistic and valuable way to realize ISD as a social process. By using information system development, RTD can communicate through organizational work as well as information system building process within the organization. Eventually this change in existing organizational routines can play positive impact on RTD. (Question 3)

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.

Evaluation of information system in general can be divided into pre development stage of a system known as formative or post development of an established system also known as summative. This is considered a practical distinction before we start an information system evaluation process. Besides the complexity and immaturity; whether it is a pre or post development stage evaluation, we should also study the time line of the evaluation process and the desired output that is to be measured since evaluation can be time consuming and resource demanding. Thus, these must be accounted prior to the evaluation process.

The frameworks improvement life cycle, in its variation shapes, stays one of the most seasoned yet still broadly utilized strategies for programming advancement and procurement techniques in the data innovation (IT) coliseum. While it has developed throughout the years in light of regularly changing situations and outlook changes relating to the building or gaining of programming, its focal inhabitants are as material today as they ever were. Life-go stages have experienced emphases of distinctive names and number of steps, however at the center the SDLC is flexible in its time tested organization in business, industry, and government. During the requirements gathering and investigation stage, it is critical that a large portion of the significant prerequisites are caught precisely. It 's best to have the same number of gatherings as important to ensure the customer 's needs are caught on. At the point when examining the prerequisites, you ought to attempt to distinguish any dangers and offer procedures for danger moderation.

There are many development methodologies for creating information systems. One of the more popular methods, developed in 1970 by Winston Royce, was the waterfall methodology. The waterfall methodology required that a team follow a prescribed sequence of five major steps when developing an information system. The project phases are linear and performed in a very methodical order starting with requirements analysis, then moving to design, followed by implementation, verification, and finally maintenance (see Exhibit A.). This methodology has been in place for many years but the highly structured methodology posed some major challenges. One major problem is when the business users dramatically change the requirements in later phases. This results in major rework and in some cases even project failures. With the advent of the Internet and Web-based technologies, the systems development community needed a more flexible methodology as projects were under greater pressure to deliver systems faster. Then in 2001, a small team of technologists created an iterative agile development methodology which forced systems development efforts to be broken up into smaller manageable timeframes called “sprints”. These iterative sprints contain a set of manageable system components allowing the teams greater flexibility when producing software (see Exhibit B). According to the Agile for Dummies text, “Agile is an attempt to make the process of software development lean and effective, and it’s

Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1).

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:
