The selection of proper enforcement of standards is the challenging task right from early stage of software engineering which has not got definite importance by the concerned stakeholders.

A new decision should be addressed for the developing of every new system feature and its quality objectives.

Unsourced material may be challenged and removed. The management of coupling and cohesion of the software. Software maintenance in software engineering is the modification iiso a software product after delivery to correct faults, to improve performance or other attributes. A very common situation which often degrades performance is lack of suitable maintenance tools, such as defect tracking software, change management software, and test library software.
