The traditional development environment for many organizations has been manual and time consuming because developers must build out new features to the end without quality measurement. This approach also assumes that users know and can specify all the desired requirements and software properties with precision before developers can start building the final product.
However, this development style is desirable when software requirements are predictable and stable. Besides, with the traditional development approach, the client’s participation mainly takes place at the beginning of the project, which means that the end-user usually provides limited feedback for later development phases.
The development and deployment styles are also hard to adapt to small projects that change constantly. Unfortunately, a broad array of modern applications requires code development that takes place in diverse platforms and tools. DevOps teams, therefore, should establish a mechanism to integrate and validate application changes promptly.
