Guide to SAP Rapid Application Development

SAP Rapid Application Development is a tool that helps you build and deploy applications faster. The tool mainly focuses on gathering customer needs through workshops, early testing of prototypes by customers, continuous integration, reusing existing prototypes and rapid delivery. With SAP Rapid Application Development, you can use your preferred development and deployment method.

In this post, we’ll show you the ins and outs of SAP Rapid Application Development and explain why you should be considering it.

How SAP Rapid Application Development Works

Since RAD uses minimal planning to promote rapid prototyping, it enables developing the functional modules in parallel with the prototypes and integrated to complete the product and encourage faster product delivery. The lack of detailed preplanning makes it easier to make changes while still in the development phase.

RAD projects have an incremental and repetitive model are made up of small teams of domain experts, developers, selected customers and other IT players, each progressively working on their prototype. This model will be successful if the prototypes developed are reusable.

RAD model design

RAD model achieves short product development times by making short iterative development cycles from the analysis, design and test phases. Below are the five phases of the RAD model.

Business modelling

The design of the product’s business model focuses on the flow of information and how the information is distributed between business channels. An analysis is done to determine the business’s vital information, how to obtain the information, how and when the information is processed and the factors promoting its successful flow.

Data modelling

This is the stage where all the data gathered in the first stage is reviewed and analysed, and refined to form a set of data objects that are important for the business. The relationship between the data objects is also established and defined to fit the business model.

Process modelling

This stage involves transforming the data object declared in the previous phase to achieve the information flow needed to implement a business function. During this stage, the procedure for any enhancements or changes to the data is defined through guidelines for adding, deleting, modifying or retrieving a data object.

Application Generation

This is the application development stage where automated tools are used to make the actual system by converting processes and data models into prototypes.

Testing and Turnover

The independent testing of prototypes during every iteration reduces the overall testing time in the RAD model. However, this does not eliminate the need to test the data flow and interfaces between components thoroughly. The thorough testing reduces the possibility of major issues.

Why choose Rapid Application Development?

RAD’s main advantage is that it enables rapid delivery by reducing development time due to parallel development and the usability of components. RAD will only work perfectly if there are highly skilled engineers and the customer is willing to have the target prototype within the stipulated time. Lack of commitment from either side will lead to failure. Some of the advantages of RAD model are;

  • SAP model helps businesses to reduce backlogs and development time through improved collaboration between business and IT
  • Through SAP model, businesses can build cloud apps that make digital access simple, scalable and secure by connecting people, processes and intelligent technologies.
  • RAD model will help you develop business apps that leverage and extend SAP/4 HANA functionality for better customer experience, improved efficiency and better employee engagement.
  • It is easier to measure progress.
  • SAP model encourages customer feedback.

RAD Model Application

A business can successfully apply RAD model in projects in which clear modularisation is possible. This is because RAD is more likely to fail if it is impossible to break down the projects into modules. Below are some of the scenarios where organisations can use RAD:

  • RAD should only be used if it is possible to modularise a system to allow delivery in an incremental manner.
  • When modelling designers are highly available.
  • When the use of automated code generating tools is allowed by the budget.
  • When domain experts have relevant knowledge of the business.
  • When there is change of requirements when working on the project and you are required to present the working prototypes in small iterations of less than four months.
