How We Work – Agile VS Waterfall MethodologyAgile Methodology, Software Development | 0 comments | by Erin Quilliam
When considering a software development company to work with, one of the factors in your decision should be the development methodology which they use. This is because it will affect how the company works, how involved you will be, and how timescales are managed. Agile and waterfall are two of the most common methods so today we will pit them against each other and examine the agile vs waterfall conundrum.
Each method has its own ways of working, and as such, different benefits or drawbacks. We’ll look at what those are for both methods.
Here at IT Enterprise, we prefer to follow a software development methodology known as Agile Methodology. This is because Agile has many benefits for you – the client – compared to other methods.
Read on to find out more about what Agile methodology is and the benefits it has, and find out if it will complement your own ways of working.
This article only focuses on agile vs waterfall. But there are other methodologies available. You can read more about other software development methodologies and their pros and cons here.
Agile vs Waterfall Methodology
Agile is seen as the “modern” way of working in software development, in contrast to Waterfall Methodology, or Traditional Methodology. Waterfall has been the standard way of working for decades. But what are the differences, and why do we choose to use Agile?
As mentioned above, Waterfall methodology has long been the standard way of working. This system follows a very linear process. (Shown in the graphic above.) It involves separate stages that are completed before moving on to the next stage. Each stage typically covers a separate step in development, such as design, or implementation.
Waterfall methodology requires little interaction with the client. The main interactions are before the start of development, to inform the developer of all their requirements, and after the build when they get to see the software. This can be good and bad.
On the plus side, limiting interaction means there is going to be no need to wait for feedback before continuing to another step, saving time. But it does mean the project is quite rigid, with little to no opportunity for alterations should the client’s requirements change.
This rigidity has some benefits, such as making it more likely to meet deadlines and knowing the project outcome from the start. However, this lack of flexibility comes at a cost with the lack of communication.
Additionally, because major testing is not carried out until towards the end of a project, it can cause issues. Such as if a significant bug is found – or requirement change needed – it will require a huge overhaul. Maybe even starting afresh.
In contrast, the agile methodology requires a lot more interaction with the client. This allows the client an early opportunity to see the work, and regular chances to see progress and make suggestions or changes should they wish to.
This is because Agile methodology means development is done it iterative cycles. (As shown in the graphic above.) The developers aim to build a software solution to meet the client’s needs, which they then feedback on or add to, and then these improvements and changes are made, reviewed again, refined again, and so on until the product is complete.
This method is great to give projects flexibility, and the client the opportunity to see their solution in progress. If they find it isn’t meeting their needs, they can feedback and changes made to the software does exactly meet their needs. Additionally, testing can be carried out throughout the project. And if any bugs are found, they can be fixed in the development process.
This increased communication and flexibility does mean that deadlines may also have to become flexible, as work in each iteration may be more or less than first thought.
Agile vs Waterfall – Why We Choose to be Agile
Here at IT Enterprise, our goal is to bridge the gap between the highly technical and the everyday. This means working in a way that keeps you informed.
We do this by communicating in a way that you will understand. We won’t try to confuse you with jargon, and always explain any work we do in plain English. It also means regular communication, which is where Agile comes in.
Additionally and most importantly, we want the software we create to exactly meet your needs. To be able to deliver a product that not only visualises your great idea but makes it a working reality that reflects the needs of you and your customers. Agile lets us create a relationship with you and create software that is perfectly suited to your requirements, even if you only realise these requirements during the project.
Our aim is always to create custom software for you that makes your work more effective and efficient, but without encumbering you with heavy technical requirements. Working in an Agile way allows us to do this.
If you have an idea, let us help realise it. Make IT a reality with IT Enterprise. Your custom software could save you time, make you money, or even revolutionise your workplace. Maybe even the world!
