Application Lifecycle Management (ALM) is a way to manage the different phases an application (like a computer program) goes through from the time it is created until it has been used for a while. ALM helps developers understand when and why changes need to be made to an application in order to keep it working properly. ALM also keeps track of how well an application is performing to make sure it is doing the job it was designed to do. ALM makes sure that an application is running efficiently by monitoring how it works and watching out for any potential problems. With ALM, developers and engineers can get feedback on how the application is working in real time and make adjustments as needed.
