Systems Development Lifecycle methodologies are generally made up of fixed steps in the
software development cycle. Here, the process follows a very precise pattern: requirements to
design, from design to development, then comes the testing stage and finally the maintenance
stage. (Indusree, 2018)
As you can see, this methodology follows rigid steps, and the project cannot be modified once
the process has started. In addition to its rigidity, this method requires a significant amount of
time to get the software operational.
In the Agile development method, the end users have the possibility to make changes during
the whole development process. This method is more flexible than the previous one.
The Agile development methodology proceeds through a repetitive and incremental approach
to development (Indusree, 2018). Several iterations are created during the process and for
each iteration, the stakeholder needs to have a say to ensure that its needs have been taken
into account.
So, we can say that the Agile methodology differs from the Systems Development Lifecycle
in that it is flexible and allows the different stakeholders to make changes throughout the
development process, anytime the need arises.
The System Development Life cycle methodology is often applied in cases where the
specifications are very precise. The end user is sure of what he wants and can ensure that
there will be no changes during development. In cases where the requirements or the end
product is not clearly defined, the Agile methodology should be used.
This aspect is at the same time one of the big disadvantages of the Agile method, because due
to its flexibility, one can start the development process without clear documentation, and one
does not really know what to expect at the end of the process because of the many changes
that can be made upstream.
