The software development cycle (SDLC) is a process for designing, developing, and testing software since the 1960s. In general, it will always lead you through development phases that follow a logical order until a final product is created.
Of course, this is just to define SDLC in a nutshell. There's more to it than this oversimplified description, and you'll further understand it once you dig deeper into various SDLC models.
SDLC models such as Waterfall, Agile, Iterative, and DevOps have been used by organizations and teams to develop various systems. It goes without saying that utilizing development stages is necessary to come up with a finished product. But, certain changes have arisen as time goes by. Here's how some SDLC methodologies have evolved over the years.
The waterfall is known as the most straightforward one among all methodologies. It stands out among others due to its developmental tasks done in a sequential, specific order.
Although it's one of the pioneers of SDLC methodologies, organizations have seen challenges in utilizing it. Nowadays, only large projects that require complex regulation and tests are the ones that still use the Waterfall methodology.
The Iterative approach uses iterations, or multiple smaller cycles that are repeated. With this methodology, each phase is considered a mini-project that can add more value as the project progresses.
Nowadays, the Iterative methodology is seen as a set of small waterfalls.
A number of organizations are going for the Iterative approach for smaller projects, as frequent feedback is encouraged. On top of this, it also poses less risk as each cycle is shorter and less complicated.
For organizations whose utmost flexibility is the main concern, the Agile methodology is the right fit. It allows cross-functional teams (that also include customers and end-users) to self-organize and conduct on-going processes instead of succeeding steps.
One of Agile's strongest characteristics is the fast delivery of software testing. Moreover, this testing is done more often. These days, managers and developers are finding new tools and ways to focus on developing and testing software faster by means of task automation.
In a fast-paced industry, more and more companies are switching to the DevOps methodology. It undergoes continuous and frequent feedback, including the automation of manual processes.
Before, organizations and teams would fall short on the latter part, which involves automation testing. Later on, modern tools have been found to be helpful. These tools help organizations in automating a variety of developmental tasks as they receive up-to-date, live insights.

The Latest Trends in Software Development Life Cycle Methodologies
Since software is becoming necessary for every organization, the right software development life cycle (SDLC) methodology is essential too.
This should come with proper planning before selecting the most appropriate SDLC approach for your next project. Each has pros and cons, and organizations need to weigh them.
But over time, these methodologies also adapt to changes.
Trends emerge as people discover and develop more tools that will help them in different processes. That's why it's important that you know the implications of these trends, so no matter what SDLC you choose for your project, you will succeed.
