What does ADM mean in DEVELOPMENT

Application Development Maintenance (ADM) is the process of maintaining, enhancing and updating existing code in a software application. This includes any bug fixes, enhancements to the application's functionality, data migration tasks and other such tasks to ensure the software runs as expected.

ADM can help improve the overall performance of a software application in terms of speed, reliability and quality. It can also help extend the life span of an existing application by making sure it remains up-to-date with new technology advancements. Additionally, it helps reduce costs by avoiding costly rewrites and maintaining legacy applications.

Typically software engineers and developers are responsible for carrying out maintenance activities as part of ADM. However, other roles such as project managers, system analysts and business analysts may be involved when more complex development or maintenance processes are carried out.

Depending on the scope and complexity of development activities performed during ADM, a variety of testing methods may be employed to ensure that features work as expected and that no issues have been introduced into the system as a result of maintenance changes. These include unit testing, functional testing, regression testing, integration testing and user acceptance tests among others.

The frequency for performing maintenance activities under ADM depends on several factors such as the number of users using the software application, frequency at which updates or enhancements need to be introduced to keep pace with technical changes in industries or markets being served by the application etc. Ideally it should be done regularly depending upon these specific factors for optimal performance and efficiency gains from existing applications.

Many recurring tasks associated with Application Development Maintenance can be automated using scripts or tools like configuration management systems (CMS). This automation reduces manual effort required for running tests thus saving time spent in performing redundant tasks repetitively while ensuring consistency across different deployments or environments where applications are used.

Versioning control is one method used while performing maintenance activities under ADM where different versions or stages of an application’s source code can be tracked from its initial development phase through multiple releases over time till present iterations which makes understanding past decisions taken while developing an application easier when reviewing certain areas later on when modifications or updates come up again especially when looking at long term goals for improving overall performance & scalability.
