You’ve probably heard about the waterfall process model. Seems somewhat obsolete these days, right?
So, you’re likely more into the iterative process model. Well, what if someone combined these two? Sounds innovative, doesn’t it?
The truth is that this is nothing new since the first spiral model in software development emerged in… 1986. It was introduced by Barry Boehm. Granted that you want to know more about that model, buckle up and keep on reading – it’s all here.
If you’re one of these people who have the ‘TL;DR’ thing, here’s a brief info of what you can expect from this article. You’re welcome!
In software development, the risk is definitely something that should be avoided or at least reduced. The spiral model comes in handy in this matter. Do you know what SDLC (Software Development Life Cycle) is? If not – check our article about SDLC models. However, you should already have that knowledge, since you’re here reading about the spiral model. As mentioned above, the spiral model is helpful in risk handling, especially in large projects.
At first glance, it looks just like a coil. Probably that’s why it’s called the spiral model. The point is that each loop of this spiral represents a specific phase in the software development process.
How many loops should be there? It depends on the project. It’s up to the project manager who takes care of determining the number of phases in a particular case. And that’s precisely what our expert project managers at CSHARK do.
Firstly, you should pay attention to the radius of the spiral. It represents the costs at any point. So, briefly – it helps keep your budget in line. Cool, right?
Well, that’s not all. You can also keep track of the progress at a glance – the angular dimension shows exactly that aspect of every phase. Moreover, there are quadrants, and they also have a special meaning. Here’s the long story short:
Every successful project starts with setting goals and analysis. This quadrant also contains the space for estimating the costs, identifying requirements, and figuring out possible alternative solutions. We know it works well, and that’s why custom software development services is our bread and butter. No budget burnout here, we value resources (such as time and money).
Time for evaluation. As you know, time is money, so it’s best not to waste it on developing unsuccessful solutions. In this phase, our pros select the best possible option for further development. And then, they take care of identifying the risks and implementing a proper strategy to ensure security. It’s crucial, as the new game-changing digital product cannot be vulnerable to cyberattacks. Of course, there’s more to that than only cybersecurity. It’s about finding any flaws in the product and resolving the issues.
In this phase, the experts take care of what they do best – building software. It’s all about crafting the architecture, creating miracles in terms of remarkable product design, building the prototype, testing, and finally deploying the result. Basically, this phase ends with a physical result that comes from the two previous phases. However, there is one more quadrant to go – the newly created software needs to be evaluated.
If it’s the end point of the spiral – the new product is ready. But as there are many loops along the way, it’s the phase of evaluation. The team is focused on finding out what worked and what didn’t. Depending on the project, the software can also be evaluated by the customers. Anyway, it’s time to review the result of the effort and move on to the first quadrant – plan the next steps and repeat the cycle.
It’s true that the spiral model combines the waterfall model and the iterative model. But it has much more to offer – it incorporates the prototype approach, as well as has the valuable aspects of the evolutionary model. Risk is kept at bay, as this model enables the option of providing the scope to create a prototype at every phase of the development. Moreover, continuous analyses in every loop help identify the issues along the way. Now that is flexibility! Sounds impressive? Keep on reading, we’re going to tell you more about the pros and cons (yes, there are such) of the spiral model. Ready? Let’s go.
You already know that this model is useful and has many advantages. Surely, it helps developers work smart and productively at the same time – the large projects can be chopped into smaller parts, which are much easier to handle. What are the other benefits of using the spiral model?
As with any other thing in the world, there are some limitations – this applies to the spiral model as well. Let’s see what are the disadvantages of this model.
There is one more thing worth mentioning – when the spiral model is the best option and why? Think of it as a summary. Worry not, we will keep it short. Here’s the list:
As you can see, the spiral model can be very useful, unless it’s a small project (and a small budget).
This model helps make things simple – which is something we value at CSHARK (see who we are and how we work). We’re not fans of being busy, we’re fans of being productive.
