Software development has truly come a long way since it was first introduced. From the very line to line procedural programming methods to object oriented based programming, the development of a software or an application program has seen tremendous growth and changes.
Like most changes, when it comes to models in the software development process. This particular field too, has seen quite a number of changes as well as additions. From the very first Waterfall model to complex Spiral models, there are quite a few out there with their own pros, cons and abilities.
That being said, the model we have decided to put under our scrutiny today holds quite an important place in the hearts of most developers out there.
The RAD model or Rapid Application Development model is one of the most sought after models out there when it comes to developing softwares in the most efficient and flexible way possible.
Something, which definitely is something most developers and programmers long for while working on projects.
Top 10 Benefits of using Rapid Application Development Model
Since, you are already here looking for the top benefits of using RAD models. I guess it is safe for me to assume that you already know what and how an RAD model works.
Hence, let us head straight away to the part where we can go on discussing some of the key benefits that the Rapid Application Model has to offer and how you can use them to get the best of results for your future projects.
1. Fast work progress
When it comes to product development, rate of progress is something which is always vital for the reputation of both the product as well as the developer.
More importantly if the work progress is accountable and measurable, it is even better to come up with a solid time goal of when to finish a particular project and when it can be expected to be handed over to the end-user.
Such things, with the help of the RAD model is quite easily possible due to its iterative properties which helps the developer to make use of previous blocks of programs without having to write them from scratch as was the case in previous models.
2. Adjustable and Flexible
This is one of the biggest pros the RAD model has to offer over its older peers. Since the model segregates the program into various components and parts, it is easier for the developer to make quick changes and adjustments when opted out by the client or end user.
This greatly saves time as well as energy which might have been wasted if the developer had to work on the new adjustments from scratch.
3. Economical – Low Development Cost & Low Maintenance Cost
Does not really matter whether you are a developer or a client, when a product is economical both in terms of ‘development’ as well as ‘maintenance’. It is a win-win for both parties involved.
Just as I mentioned earlier, since the whole RAD framework is pretty much adjustable and can be picked up from anywhere when a change is required.
It greatly reduces the cost of development which might have been needed if a developer had to build the whole program right from scratch just to add a few changes.
This is the same for maintenance as well. At times, when there might be a bug or error which needs to be taken care of as part of maintenance, with the Rapid Application Development model, it can rather be taken care of much more simply and quickly. Thus, reducing the cost greatly for both the cases.
4. Less Errors
Since this model makes use of the same repository or blocks of programs most often, errors too are seen quite less frequently in comparison to that of more traditional models like waterfall where everything needs to be developed and written from the start giving way to more human errors.
Moreover, since the framework for the RAD model is well categorized and segregated, it is much more easier to detect errors that may persist in a certain part or component of the program and dealt with accordingly as remotely and specifically as possible
5. Feedback Oriented Design
One of the major drawbacks of traditional models was that there was never any kind of feedback or whatsoever from the client side during the whole process of development.
This as a result always ended up in difference of opinion or mismatch of expectations between the developer and client or end-user after a product or software had been delivered.
To counter this difference in opinion at the end, the RAD framework hence made use of constant feedback from the client side to make changes as desired and required during the development process, so that the end product has every little thing included which might be needed to produce a complete and whole product that satisfies the need of the end-user.
6. Segregated Software Components
With working principles similar to the ones involved in object oriented programming where components are well segregated from each other and work independently on their own without interfering with the working of the other.
Even in the case of the RAD model, each component or element is broken down into separate entities and worked on separately so that when any changes or adjustments are to be made as mentioned earlier. It can be easily done without affecting the other components.
Given that the model enables the developer to easily adjust as well as make changes in his or her software, adaptability is something which naturally comes by.
It does not matter whether you need to add new functionalities and features to your software with the passing of time. As long as you have the RAD model, doing that is quite easy and can be done without much hassle and effort.
8. Quicker Version Releases
It is quite obvious that since the time required in the developing process as compared to previous models is greatly reduced.
Coming up with new versions and releases which is something that is very much required in today’s global market can be quite readily achieved with the particular model.
New versions and releases not only help the developer come up with better versions of the product with respect to end-user feedback.
But also, keeps the user or client engagement going which more or less works as a lifeline for most projects out there
9. Measurable Progress with better risk analysis & control
Anything which is measurable can help greatly when it comes to developing a product or in our case a software.
Being able to measure the progress as well as counter effectively analyze the risks associated with it can help a long way to prevent any catastrophic events at the end of the development process. Something which could be seen previously for the previous models quite frequently.
A successful risk analysis as well as control over what and how to go on with the development process there on can greatly help decrease any losses which may occur in the future if such risks are not taken into account when the time is ripe and right.
10. Easily Integratable
Another major pros, which is my personal favorite, is the amount of integrability the RAD framework has to offer.
Previously in the case of older models, integration with other softwares or applications was something which was quite difficult to achieve. However, in the case of RAD, integration can be quite easily achieved and in no time without any hassle.
Hence, all these benefits greatly help increase both client satisfaction as well as developer satisfaction, something which was mostly downplayed in previous models of software development.
Just like Client satisfaction, Developer satisfaction too plays a vital role in producing products or software which are quality oriented and not just quantity oriented.
Only when both parties are satisfied with what is being developed and the end product, can we surely say that the end product is successful. Something which has been made possible with the RAD model ever since it was first introduced in the 80s.
