SDLC methodologies are an essential part of any development process. For those who wonder what does SDLC stand for, it is software development life cycle. An SDLC life cycle dictates how a piece of software is developed, tested, and released to the marketplace. Secure SDLC ensures that you create an incredible piece of software that cannot be hacked.
Before choosing one of the various SDLC models available, it is essential to understand what types are available and how they can help your development process. By knowing what SDLC is and how to implement it correctly, it is possible to succeed far beyond your expectations.
The Best 6 SDLC Methodologies to Consider for Your Company
Before diving into agile SDLC and other complex SDLC terminologies, it is important to look through all of the available SDLC methodologies on this list. By fully understanding their benefits, you can improve your development implementation and get high-quality software.
1. Waterfall Model
The waterfall model is one of the most basic SDLC methodologies. It works linearly to complete various tasks that help improve development speed. This process shape means that a development phase will only begin the moment that another period finishes. It is a particularly beneficial model for relatively straightforward concepts.
We suggest this method for projects which don’t require regularly changing the requirements of development or which are minor updates of past software. For example, an update of a word program probably doesn’t need significant changes to be successful. As a result, the waterfall method is an excellent choice because it can streamline a product’s operation.
There are a few disadvantages to people using this method. For example, it’s hard to go back to a completed phase if adjustments need to be made. It is also a relatively slow process that takes a little more monetary investment to implement. These negatives mean it isn’t quite right for a company that is starting out or which needs a product quickly.
2. Prototyping Model
The prototyping model is one of the quickest types of SDLC methodologies. It requires creating an incomplete version of a piece of software that gives your customers a basic idea of what to expect from it. It is a beneficial choice if you need to show off a product quickly or if you have a lengthy development time during which you can tweak your model.
Unfortunately, prototype models are discarded after the product is completed. This action causes a disadvantage because it means you spent a lot of time working on a design that wasn’t used. Prototyping is also problematic because it gives your customers a rough idea of the final product. It should only be used if you need a quick model to show to a potential customer or buyer.
3. V-Shaped Model
Of all of the SDLC methodologies we have discussed, the V-shaped model is the one that resembles the most the waterfall model. It varies in its implementation because it arranges the development process in a slightly different manner. Rather than working on a comprehensive plan that moves linearly, you develop your software in a bent manner that creates a V-shape.
For example, you could use this method to create broader aspects of the coding and then simplify your operation to the final product. While this is a simple process that has specific steps that are easy to understand, it is inflexible and hard to adjust your scope when implementing it.
4. Agile Model
The agile model is one of the most reactive, yet beneficial, SDLC methodologies. It uses the concept of customer interaction to allow you to create a product that fits their needs. For example, you can get feedback on each stage of the project to ensure it meets all quality standards.
This model helps speed up development time and make it more useful. However, it does make it harder to guess the final product development. As you continuously adjust each phase to meet customer expectations, the finished product may look and behave differently than you anticipated. While this will satisfy your client, it may confuse your developers as the product changes.
5. Iterative Model
Unlike other SDLC methodologies, this process creates a working product more quickly. For example, you create a piece of software that meets specific requirements, test it, evaluate its final results, and tweak it as needed. This produces multiple versions that vary in quality and effectiveness.
This process is one of the most popular of all SDLC methodologies but is the most expensive. That’s because you are creating a finished product that requires consistent adjustment. As a result, it can also be a lengthy and uncertain procedure that takes a longer time to finish.
6. Spiral Model
Anyone who needs flexible SDLC methodologies should try this choice. It is similar to the iterative model in that it requires a variety of phases to develop. However, the spiral model differs from that one because it uses different processes that fine-tune your software and ensure that it ends up being finished.
It takes advantage of user feedback and customization to improve the product. There are drawbacks here, though. For example, it can be a lengthy process that never seems to end. Even worse, it can confuse or upset your customers by taking too long to finish.
Summing It Up
As you can see, there are many SDLC methodologies from which you can pick. While each type of SDLC models has advantages and disadvantages, none is a bad choice. So, whether you choose an SDLC life cycle that is fast pasted or secure SDLC that requires a little more work, you shouldn’t have a hard time developing high-quality software.
If you have any more questions on SDLC phases, don’t hesitate to comment below. You may be able to help others in your same situation choose among the best possible SDLC methodologies for their needs. Beyond that advantage, we always look forward to helping people master their SDLC and develop better software.
