More so, customer feedback often dictates and identifies the needed improvements of your application. Over a period of twenty years, his research led to the formulation of Lehman's Laws (Lehman 1997). You must communicate these changes in advance and put the proper support in place once its launched. This is, probably, the most accessible type of maintenance to identify. Types Of Software Maintenance. Its important to note that software maintenance can be costly and complex, especially for large and complex systems. And, there are expected updates on your operating system, cloud storage, hardware, and other software dependencies. Preventive maintenance is a type of software maintenance . Analysis The process of analyzing the suggested modification including understanding the potential effects of such a change. An applications overall maintainability is dependent on the continuing obtainability of components of all sorts from other suppliers, including: The complete disappearance of a component could make the application un-rebuildable, or imminently unmaintainable. Software maintenance in software engineering is the modification of a software product after delivery to correct faults, to improve performance or other attributes. If the driver is stability or efficiency improvements, that is application modernization; in this case, evaluate whether the scope of the change justifies a rewrite of the application instead. The thing that was the most impressive for me was that they werent just blindly following directions. Software developers must continuously look for ways to rectify and enhance their work to be competitive and relevant.
