Since the first software was developed in the 60s, the SDLC (Software Development Life Cycle) has been the primary model used by developers. Given its long-lasting dominance, it’s important to understand how the SDLC process actually works, as well as how it's changed over the years. So, here’s a quick review.
Let’s start with the basics, and a simple definition. What is SDLC? To put it in engineering terms, it refers to the process of dividing software development into different phases—design, product management, and also overall project management.
When put together, these stages can be used to define the life cycle of virtually any piece of software. From there, it becomes possible to break these phases down into separate development processes. They include: planning, followed by analysis and design, implementation and testing, with deployment and maintenance being the final two phases in the development cycle.
Now that we’ve defined the stages, let’s take a look at the development models. The SDLC waterfall model is known as the pioneer of all models, allowing development to occur as a sequential series of tasks. This is appropriate for industries like manufacturing and construction, where complex regulation and testing for compliance are two of the biggest challenges.
Another model that has developed over time is called iterative development. This takes a piece of software, or a software system, through a sequence of cycles (or iterations). It helps developers learn from each iteration. The advantage of this kind of system is the ability to divide the software into smaller sections. This, in turn, provides more early feedback, allowing corrections to happen more efficiently. Repeated iterations enable developers to correct mistakes and apply the necessary steps for improvement.
One of the more recent developments in the last two decades was to make the process more agile. With Agile, teams can work on the smaller sections as they’re implemented, allowing for rapid, flexible changes as they become necessary.
The final evolutionary change in SDLC, at this point, is called DevOps. This allows for the creation of a coding infrastructure. It enables more automation throughout the development process.
Testing occurs automatically in DevOps, which further speeds up delivery, and even coding itself. Insights can be gleaned and used in real time, so changes in the coding base become as organic (and fast) as necessary.
