Modern software development methodologies

In recent years, software has become extremely necessary in running of businesses and affairs world over. Due to development of modern equipment and changes in business models, process automation and databases require up to date software or upgraded versions for efficiency.
In the formative years, it would take years to develop software and even after completion, its usage would still not suffice. However, due to changes and improvements in development models, it has become easier, more reliable and cheaper to develop and deploy. Increasingly, there have been better ways of developing software as highlighted below.

Methodologies for developing software

Continuous Integration (CI) method


This method improves on the traditional agile method by automating the process of development. Having in mind that the agile method divided a problem to small parts then assessing and solving them, the continuous integration method automates the process of solving those problems. This improves the dynamism of the software as changes and improvements may be done even later after the solution has been obtained. Some codes even have on/off buttons to activate the code to add new features to it. This allows software to be changed to suit the unpredictable and changing business patterns.

DevOps


As the name suggests, this method combines both the development part and the operational part of software development. Here, all the teams work together iteratively, and they assume everything to be code. This process is also continuous, and every step is automated. It brings every bit of the development together at the same time hence allowing for changes that may occur during the development cycle. Unlike in the continuous integration where development and operation cycles were brought together, the DevOps method also includes the support and maintenance team.

Both the DevOps and CI methods have been greatly boosted by the cloud technology where teams can operate remotely. There is really no big difference in the software development methods. It is the improvements and enhancement of ways of developing that has brought about changes in the development cycle. The traditional methods are known as software development lifecycle (SDLC). This was practiced by having teams working independently to develop software.
The modern methods are known as application lifecycle methods (ALM). Improvements to these cycles are still going on as changes to software needs and requirements arise every new day. For instance, there are internet tools called RAD tools (Rapid Application Development tools) that have eased software development in comparison to ALM but it is still new and not much information has been obtained concerning it. It is likely that we will see far much better technologies soon.
