Rapid Application Development (Rad) the New Approach for Systems Development

The computer software industry is a relatively new development on the international market place. Only a few decades ago, there was no such industry at all. Thanks to a number of innovative software developers, the rise of the industry has become a booming success. The industry itself increased dramatically in the 1990s. It was during this period that software was growing in a number of other supporting industries. Software soon became an integral part of industries like healthcare, business applications like databases and network structures, personal finance, and education (Kent & Williams 1997). The more intertwined it became with other business applications, the more successful software became as a

Once a tool or vendor is determined the design team will work on implementing the design. The design will be implemented as part of the project plan timeline and Smith will provide developer testing in addition to end-user acceptance testing. This ensures that the final product matches the goals of the system as laid out in the project plan. Once acceptance testing is completed the system will be implemented and the system will enter its training phase as indicated in the project plan.

These actions require a great amount of preparation and is one of the most difficult stages. The group is required to share their points of views and link them together to be able to design the perfect idea. They will have to think in advance all the way through, so that they won’t have to come across difficulties in further stages; otherwise, they would have to return to the first one.

These requirements are translated into design. A code is produced as according to the design that is created which is according to the requirement. This is called the development phase of the lifecycle. After coding and development the testing verifies the deliverable of the implementation phase against requirements [3].

In the define phase proposals are formulated, estimated and tested for feasibility. The results will be presented to the senior management in order to receive a "go" for the project which often is in the form of a contract.

Choosing a proper method for software design is completely depended upon the requirements and end products of the company. These requirements and goals might change in the process of development of software depending upon the decisions of stakeholders, developers and system analysts.

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,

To ensure a successful implementation, Clients are moved through several phases. Each phase allows Athreon and the Client to reach a series of milestones that culminate in achieving a mutually agreed upon objective. Each phase is distinct and clearly delineates specific steps, while allowing room for

The steps of phase A are about turning the request for architecture into a documented Architecture work statement and make sure the enterprise is willing to change its architecture. This includes establishing the architecture project, defining its scope, and confirming and elaborating architecture and business principles. This phase identifies the stakeholders, their requirements and business goals from the preliminary phase.

In the early days of software development, it was not uncommon for months to pass before any development began, and once development started, it could be months or years before any type of finished product was ready for testing. The requirements definition and gathering process was often very long, and in many cases the development team was isolated from the customer.

Rapid Application Development(RAD) uses minimal i.e. no detailed planning for rapid prototyping and due to this it can be easier to make changes within development process. The most important aspect of this model is to conform that prototypes that are developed are reusable. RAD model contains the phases like analysis, design, build, testing which can be carried out in small, iterative development cycles.

In this paper, Rapid Application Development (RAD) and the Agile Development Method (ADM) are compared and contrasted. The paper begins with a summary of each of the articles referenced on the title page, including the pros (benefits) and cons (risks) of each method. The paper then addresses how the two methods might be applied to my company, Parametric Technology Corporation (PTC), an enterprise software solutions provider headquartered in Needham, MA, with about 6,000 employees in over 70 offices worldwide. Finally, the paper concludes with my views on which of the two methods would be more valuable in a development setting. The authors of the article, “Risks of Rapid Application Development,” open by cautioning that software development includes – or should include – more than the speed at which an application is delivered, identifying maintainability and reusability as equally important characteristics. The purpose of the article is to fill a gap in the literature (at the time of the writing of the article) about the long-term implications of RAD tools on both the software itself and the organizations and developers who use it. The authors emphasize that the choice to use RAD is not just a capability decision, it is also a human resources management decision. In addition to a much faster development lifecycle, RAD tools also include requirements planning, design and modeling, code writing, and testing, with the requirements and design phases accounting for about 30% of

The implementation phase is where all relevant steps and processes are carried out in order to put a planned system into action. Once installed software is tested and reviewed to make sure the selected solutions are addressing the organisations requirements. Implementation is affected by multiple factors like the context of the organisation; its size, the roll out plan and current structures just to name a

This is the phase where the requirements are noted, feedback regarding requirements are obtained from users

Define Phase implementation: A Project Team was formed and a manager from the procurement department had the following responsibilities. This phase deals with defining.
