4 Basic SDLC Methodologies

The software development lifecycle needs to be improved and adapted as much as you can in order to achieve great results. However, costs can end up making the process very challenging, and there can be restrictions too. However, the SDLC methodology you use will either help you a lot or make things worse. That’s why you must study the situation and actively figure out what you can do and track everything to suit your needs really well.


The Agile approach has been around for more than 10 years. That being said, lots of companies started to use it recently because they heard about it and it’s actually great for them. The interesting thing is that it can be a suitable driving force behind development. It’s so popular that now a lot of companies use it outside the software world, which is really interesting.

4 Basic SDLC Methodologies

The idea here is that you have ongoing release cycles and you make changes iterationally with great focus on value. As you release new stuff, you are also testing everything and thus you address the small issues before you end up with problems. Software can be very complex, so making sure that there aren’t any major problems is a crucial aspect to consider here. It can totally be worth it in the end, as long as you focus on results you will be more than ok for the most part.

Some people also use Scrum which is better if you want to structure complex development tasks. Scrum works in springs and that means they focus on very specific tasks instead of everything as a whole. It does require meetings to help the team monitor everything, something that can be quite the challenge and you have to track that on your own.


DevOps is also very popular, despite being new. Here the operation teams and developers are working together and even as a team if needed. This is focused on boosting innovation and the high quality deployment of good results. The updates are small, but they are frequent. There’s a lot of need for process improvement, continual feedback, discipline as well as automation of manual processes when that is needed. This is a very good combination of practices and ideas that help add up in order to provide software and services at a very high velocity. Speed is indeed a factor here, but quality is just as important. This methodology is for guiding and planning, but some additional stuff might be needed depending on the situation.


The Lean model is great because it focuses on making the development process as simple and as lean as possible. There are 7 main Lean principles here. These are amplifying learning, eliminating waste, deciding as late possible, delivering quickly, empowering the team, building integrity and so on. With the Lean approach you just work on a single thing at a time, without having to worry about multitasking to begin with. This certainly makes it easy to not have any errors in the end, and that will certainly help a lot. The fact that you eliminate waste is very important because customers will just end up seeing the value and quality, which is crucial at the end of the day.


With the Iterative SDLC methodology you will notice that this is repetition incarnate. The team will implement the software requirements, then it will test, evaluate and figure out future requirements. You create a new software version with every iteration. Then all you have to do is to rinse and repeat as you get closer to release. The advantage here is that you have a working version early on and then you adapt and improve it to making it better. However the problem with all of this is that working with a repetitive process can be costly.

In the end every SDLC methodologies have their own approach and you have to figure out which one is suitable for you. Some focus on eliminating waste from the development process, others use iterations while others bring in lots of attention to testing. In the end you have great results either way, but picking the right one for you might be able to save quite a bit of time and money too!
