Application development is the process of creating a computer program or a set of programs to perform the different tasks that a business requires. From calculating monthly expenses to scheduling sales reports, applications help businesses automate processes and increase efficiency.


The first step involves choosing a particular a method or model to determine the appropriate steps that are necessary to develop the software.The method or model provides a general outline that guides the development process. There are several different methods or models that will be explained in more detail later.
An early prototype of the app is built to test its functionality. These early prototypes are often built using modeling tools, like SysML or UML.
The app is updated to get rid of any defects or bugs to make sure the app functions to its full potential. The app is usually not released for wide-scale use until enough defects have been eliminated and the app is deemed stable or functional. The software is then released for use.
The second step involves determining what function(s) the app should carry out. Next, an underlying system is developed that allows the app to operate. Software application developers come up with possible solutions to any problems that might occur once the app is in use.
Coders then start writing code for the app in the appropriate coding language. The code is often reviewed by peers or teams. Then, the app goes through a testing phase to determine if it functions as intended and to determine whether or not there are any unforeseen problems.
Finally, the app is managed and maintained to make sure that it continues to function as intended.
