Differences Between Traditional SDLC and RAD Model
Parameters |
RAD Model |
Traditional SDLC |
---|---|---|
Stages |
Stages are not well-defined. |
Structured Methodology and well-defined stages. |
Application Development Approach |
Different stages of application development can be reviewed and repeated as the approach is iterative. |
Follows a predictive, inflexible, and rigid approach to application development. |
Prototypes |
Follows a predictive, inflexible, and rigid approach to application development. |
Follows a predictive, inflexible, and rigid approach to application development. |
Requirements |
It is not necessary to know all the requirements beforehand. |
All the requirements should be known before starting the project due to the rigidity of the models. |
Changes |
Easier to accommodate changes. |
Difficult to accommodate changes due to the sequential nature of models. |
Customer Feeback |
Extensive customer feedback leading to more customer satisfaction and better quality of final software. |
Limited customer feedback. |
Documentation |
It involves minimal documentation. |
Stringent and extensive documentation of the entire project process is necessary. |
Team Size |
Separate small teams can be assigned to individual modules. |
As there is no modularization, a larger team is required for different stages with strictly defined roles. |
Preferred Projects |
Generally preferred for projects with shorter time durations and budgets large enough to afford the use of automated tools and techniques. |
Used for projects with longer development schedules and where budgets do not allow the use of expensive and powerful tools. |
Components Used |
The use of reusable components helps to reduce the cycle time of the project. |
The use of powerful and efficient tools requires highly skilled professionals. |
Reusability of Elements |
Usage of identified and ready-to-use themes, templates, layouts, and micro apps that have been predefined. |
Elements are not reusable since they must be created from scratch in accordance with project requirements. |
RAD Model vs Traditional SDLC – Software Engineering
Software Development is the development of software for distinct purposes. There are several types of Software Development Models. In this article, we will see the difference between the RAD Model and the Traditional Software Development Life Cycle (SDLC).
