The software development lifecycle SDLC of which RAD is just one example defines a repeatable process for building information system that incorporate guidelines, methodologies, and standards. Lifecycles should be used in all types of application development, not just RAD. A lifecycle delivers value to an organization by addressing specific business needs within the software application development environment. The implementation of a lifecycle aids project managers in minimizing system development risks, eliminating redundancy, and increasing efficiencies — and it is repeatable.
It also encourages reuse, redesign, and, more importantly, reducing costs.
Under no circumstances should RAD be attempted without a defined and accepted lifecycle. This SDLC is a process.
The software development organizations of the corporation are the process owners. The lifecycle details the activities and practices that the project teams follow to plan, build, and deploy new and existing information systems and their applications. Other goals of the SDLC are to: Reduce costs of projects by minimizing rework and maintenance efforts. Reduce cycle time of projects by providing a consistent, repeatable process to follow. Increase quality of software applications by providing superior solutions that meet customer needs.
Assist project managers in managing projects more effectively.
Provide a framework to help manage project team members, development partners, or subcontractors. This is an international programming marathon in which teams of 3 programmers compete for prizes over an intensive, continuos hour period. Teams can use their own software and personal computers and are challenged to produce a solution from a detailed written specification given at the start of the contest. They work non-stop for 24 hours to complete the task.
It is carefully designed to simulate a normal, real world commercial application. The detailed specification contains over 50 pages.
A jury of five professionals applies rigorous to judge the results and to determine a winner. I have been astonished at the quality of the winning solutions.
What is achieved within 24 hours is truly amazing. When you consider that just a few years ago it would have taken 24 months to provide the same solution it does make one wonder. The point of this contest illustrates that applications can be produced quickly, be of high quality and meet the required specification given enough motivation, the right tools and skilful people.
RAD Project Management Factors During project planning, project managers need to review, in detail, the various components when considering whether RAD should be the selected technique to use for application development. A general discussion of these factors and benefits follows. Shorter Duration The principle purpose of RAD is to develop applications within a much shorter time frame than with traditional application development methods.
Typically, the duration of RAD projects is specified at the project planning phase.
Project managers will agree with senior management, the project sponsor, and the end users that the project must be developed in 30, 60, or 90 days. This sets the tone for development and creates a sense of urgency for the project team.
This means that there is little room for indecision or lack of agreement. Project managers are often called upon to make rapid decisions. There is a danger with this approach. When done well, end users see results more quickly than with normal legacy development and are much happier. The role of the end users on the project may change throughout the project, such as designing, developing, and involving them in testing and implementation.
RAD will need a project sponsor who will champion the project and empower the end users to set priorities, schedule their time and resolve design issues among themselves, to improve communications, and to make decisions.
End users who are assertive and aggressive often thrive in the RAD environment. It is not for the faint-hearted or for people who cannot make decisions quickly.
End users must be involved on a full-time basis 40 hours per week for the entire project. Anything else places a successful outcome at risk and is unacceptable.
Use of Existing Architectures and Technology RAD is not suitable for projects that may require new or emerging technology, such as new programming languages, new network designs, new architectures, or other innovative technology.
Technical innovation is defined as the introduction of new platforms, such as hardware, systems software, database management systems, or networks new to the industry or unproven within the corporation.
Project managers will be aware of the risk that will be present using this approach. RAD makes use of existing platforms that are proven, stable, and reliable. This means using hardware that is already in use, as well as proven software and DBMS systems.
There is no room for experimentation with RAD—there simply is no time.

It is also a very good idea to reuse code, templates, and design models wherever appropriate. Remember that it is all about speed—delivering quality results quickly. Project managers must be very careful in selecting team members.
There is no time for egos, academics, or people who do not want to work. Team members must be able to sustain pressure and deadlines and to deliver results. Experienced project team members who are respected by end users are frequently the best people to have on the team.
There is no time for learning curves on RAD projects, and project team members must immediately set about delivering to agreed project plan. Project managers should provide incentives or bonuses for quality delivery of the project. Appropriate incentives, such as completion bonus, awards, dinners, or other forms of recognition should be established for success.
People make RAD successful.
The qualities and individual skills necessary for successful RAD team members are detailed later in this chapter. Application Complexity RAD is not suitable for applications that have a high degree of functional complexity or that have high transaction throughput.
These systems normally require much longer development time frames and should be avoided. Rapid development provides minimal treatment of performance. The use of an established and reliable architecture should provide an acceptable level of performance. In systems where performance is a significant requirement, a traditional development methodology approach should be used. Batch systems should also be avoided. RAD is not a good technique for developing batch systems.
The time constraints imposed on a RAD project cannot support the resolution of detailed technical issues. It enables remote teams to communicate when they are not in the same location.
End users can search and find information, specs, research products, templates, use standards, and more. The Internet is a fast place to do business, and there is a wealth of data to be mined.
Hm... Are You a Human?
In particular, on a RAD project, the team must be wary of scope creep, which usually takes the form of repeated requests for additional functionality or the addition of complexity to the project. Changes must be carefully recorded; cumulative changes that might result in an overall scope change of more than 5 percent should trigger re-estimation of the project schedule, budget and risk.
Unacceptable levels of changes when the RAD process is underway can quickly disrupt the time scale and kill the project. The team consists of a mixture of skills and is comprised of: The RAD facilitator or session leader A management sponsor.It's also used by OpenXava to know the size of the user interface editor. Springer Too much of bureaucratic code.
