What Is Software Development?

Computers and networks, smartwatches, vehicles, smartphones video games, and the countless applications that are part of our lives every day – all rely on software to function. These digital devices, as well as many others, are creations of software developers, who are the creative brains behind these applications.

Software development is the process of bringing the idea of a program from conception to its release. It is a methodical process that starts with a thorough requirements analysis. This transforms the user’s needs and wants into a functioning software system. The Software Development Life Cycle (SDLC) outlines the steps of this process. Following this framework allows developers to develop software that is of higher quality as well as lower costs and shorter time to produce than other methods.

Testing is an essential part of any software development project. It makes sure that the application is free of errors and work in accordance with the specifications. Depending on the scope of the application it could include functional testing, regression, compatibility, and load testing.

Performance testing is used to determine an application’s response time under peak and normal load conditions, as well as its ability to scale. It evaluates how the application performs under changing numbers of concurrent users and transactions, as well as determining the capacity of the network or hardware needed to host the application.

Innovative technologies that require complex software programming are always emerging which is increasing the need for developers. Examples include the internet of things, where automobiles, homes and industrial machines communicate using sensors and microprocessors as well with artificial intelligence-powered programming which allows software to complete tasks like emulating human decision-making and learning.
