Rapid application development

RAD is an agile project management strategy popular in software development. The key benefit of rapid application development approach is fast project turnaround, making it an attractive choice for developers working in a fast paced environment like software development. This rapid pace is made possible by RAD’s focus on minimizing the planning stage and maximizing prototype development.

By reducing planning time and emphasizing prototype iterations, rapid application development allows project managers and stakeholders to accurately measure progress and communicate in real time on evolving issues or changes.  This results in greater efficiency, faster development, and effective communication. There’s few ways which you can break down the process, but in general RAD follows four main phases.

The basic break down of this stage involves

1. Researching the current problem
2. Researching the current problem
3. Defining the requirements for the project
4. finalizing the requirements with each stakeholder’s approval

 2: User design 

Once the project is scoped out, it’s time to jump right into development, building out the user design through various prototype interactions

RAD methodology is meat and potatoes and that’s what sets it a part from other project management strategies.  during this phase client work hand to hand with developers to make sure their needs are being met at every step in the design process. It is like customize software development where the users can test each prototype of the product, at each stage to ensure it meets their expectations.

3: Rapid Construction

Phase 3 takes the prototypes and beta systems from the design phase and converts them into the working model.

Because the majority of the problems and changes were addressed during the through iterative design phase, developers can construct the final working model more quickly than they could by following a traditional project management approach.

The phase breaks down into several smaller steps:

• Preparation for rapid construction
• Program and application development
• Coding
• Unit, integration, and system testing

The software development team of programmers, coders, testers, and developers work together during this stage to make sure everything is working smoothly and that the end result satisfies the client’s expectations and objectives.

4: Cutover

This is the implementation phase where the finished product goes to lunch. It includes data conversion, testing, and changeover to the new system, as well as user training. All final changes are made while the coders and clients continue to look for bugs in the system

Benefits of RAD methodology

RAD is one of the most successful software development programs available today, with numerous benefits for both software development teams as well as their clients.

Advantages of the RAD model:

• Reduced development time.
• Increases re usability of components
• Quick initial reviews occur
• Encourages customer feedback
• Integration from very beginning solves a lot of integration issues.

Disadvantages of RAD model:

• Depends on strong team and individual performances for identifying business requirements.
• Only system that can be modularized can be built using RAD
• Requires highly skilled developers/designers.
• High dependency on modelling skills
• Inapplicable to cheaper projects as cost of modelling and automated code generation is very high.

web projects fail there’s no secret about that, while traditional application development approaches are the single biggest factor in this failure but it is lesser known about it.  Traditional methods of software development such a SDLC, are known for having clear objectives, stable requirements and measurable progress of development. They are time consuming, n have minimum iterations and there’s very little customer interaction.  traditional application development methodologies and tools are unable to fulfill the demands of modern enterprise applications.  The failure is not just for web applications, traditional methodologies are not perfect match for mobile application development as well.

Rapid Application Development Vs Traditional Methodologies

Parameter	Rapid App Development	Traditional App Development
Application Development Process	Incremental and iterative. Different phases of development are revisited as required.	Linear and predictive. Follows sequential flow of application development.
Team Structure	Small teams with intermediate technology skills, good business knowledge and communication skills. Thin project management layer.	Large teams with strictly defined roles and technology skills.Well-defined project management layer.
Productivity and Flexibility	High productivity and flexibility due to iterations, end-user interactions and use of predefined elements leading to faster turnaround time and low waste.	Low productivity and flexibility due to linear, rigid approach. Exhibits wait times and waste at each
stage, leading to high cycle times.
Documentation	Minimum viable documentation as the deliverable at every iteration is the code/app itself.	Involves stringent documentation and reviewal at every stage of development.
Time and Cost Estimation	Short duration projects with small variance in the cost estimation. Low maintenance costs.	Medium to long duration projects with high costs. There are chances for additional increase because of reworking and maintenance costs.
Testing	Testing is performed at every iteration.	Testing is performed after completion of coding phase.
End User Interaction	Extensive user interaction with reviews and suggestions on timely basis during every iteration and phase.	User is involved at the beginning during the requirements stage and then in the end delivery during user acceptance stage.
Predefined Elements	Use of predefined themes, templates, layouts and micro applications which are tested and ready-to-use.	Elements have to be designed and constructed from the ground up as per project requirements and hence, are not reusable.
