Welcome back to CyberRays is. Of course. I'm your instructor. Brad Roads. Let's jump into modulate the system development life cycle.
So where are we on our s A journey? Well, we just finished. Module seven, The ISI process, which took and applied hopefully for you. All of the different things we talked about in the sub domains. Now we're into the system development Lifecycle module eight. What? We're gonna talk through how
systems engineers from a nest perspective actually develop and build
their creations. If you will on, then we'll follow on and talk very specifically about keenness standards. You need to know for the ESOP examine module nine.
So in this video, we're going to cover our module objectives briefly on. Then we're gonna review real quick the types of development because that's gonna be important in our discussions of the system development life cycle.
So our module objectives, you are pretty straightforward. We're gonna real quickly and just a just a slide. We're gonna review those development types. You wanna have those in the back of your head when you think about the SCLC, and then we're gonna investigate the five phases of the system development life cycle, which is
the standard now it's actually about to change into something else, which we'll talk about in our nest standards.
So remember, there are four development capabilities or development processes we talked about. The first one we talked about was waterfall, so that's cascade of process is very linear. Created in the 19 seventies, Onda very hard to change A Z went through the process and
sometimes from a systems engineering perspective. With waterfall, you get to the very end
and you don't have the product that you quite expected you were going to get. And that's the danger of waterfall. The next developed in the 19 eighties, was the Systems Engineering V, and that's where we go from concept development all the way to transition operations and maintenance after we've tested in this case here. This is where we really saw the terms of verification and validation.
We're verification is determining whether we met requirements
and validation is our. It does the product, the security control, the system, the capability, whatever does it meet the mission or vision business need. And as we talked about multiple times, it is possible to verify a product but not validated
Of course, In the 19 nineties we saw the beginnings of something called Spiral. And this is one of the first processes where we saw iterative process of our product development. And so that's where we saw prototyping. So this is the first introduction of prototyping. And what was nice about that one in specific to spiral is that now,
if a prototype didn't quite work, you could go back, re prototype and move forward. Right? So
that was nice, then, of course, the coup de gras, if you will of development cycles is the agile process.
And so agile itself is a widely used process across multiple industry verticals. Now, not just security, not just information systems and I t. But all over the place, you see, agile, applied because agile conceptually is a great way to get all sorts of products out the door. And so agile is the other product type
our product development cycle
that we talked about.
So in this video, what did we cover? We reviewed our module objectives on We
briefly walked through development models because you need to have them in your head for a quick portion of the system development life cycle that we're gonna talk about.
We'll see you next time
