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. Every app-building process follows the same steps: gathering requirements, designing prototypes, testing, implementation, and integration.

There are lots of factors that go into how application development is done. You must consider the size of the project, how specific the requirements are, how much the customer will want to change things, how large the development team is, how experienced the development team is, and the deadline for the project.

Application development is closely linked with the software development life-cycle (SDLC). The way that application development teams have accomplished these seven tasks – Planning, Analysis, Design, Construction, Testing, Implementation & Support has changed a lot in the last few decades, and numerous types of application development methods have emerged. Each methodology must provide a solution for the seven stages of the SDLC.

There are 2 different methodologies followed for delivering Application Development i.e. Waterfall & Agile. Waterfall is step-by-step process of following the seven steps of SDLC; however Agile focuses on incremental improvements & delivery of MVP (Minimum Viable product).
