Software Maintenance Planning
An integral part of software is the maintenance one, which requires an accurate maintenance plan to be prepared during the software development. It should specify how users will request modifications or report problems. The budget should include resource and cost estimates. A new decision should be addressed for the developing of every new system feature and its quality objectives .The software maintenance, which can last for 5–6 years (or even decades) after the development process, calls for an effective plan which can address the scope of software maintenance, the tailoring of the post delivery/deployment process, the designation of who will provide maintenance, and an estimate of the life-cycle costs 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. Software maintenance takes more effort than all other phases of software life cycle, but it has not been given as much importance as it deserved. It is an admitted fact that approximately 60 to 70% effort is spent on maintenance phase of software development life cycle. Software maintenance is classified into corrective, adaptive, perfective and preventive maintenance. According to IEEE, corrective maintenance is the reactive modification of software product performed after delivery to correct discovered faults, adaptive maintenance is the modification of a software product performed after delivery to keep software usable in a changed or changing environment, perfective maintenance is the modification of a software product after delivery to improve performance or maintainability and preventive maintenance is performed for the purpose of preventing problems before they occur. In this paper the main focus of authors is towards corrective maintenance to overcome the all problems arising in requirements, design, coding, documentation and testing activities.

Famous quotes containing the words maintenance and/or planning:
“However patriarchal the world, at home the child knows that his mother is the source of all power. The hand that rocks the cradle rules his world. . . . The son never forgets that he owes his life to his mother, not just the creation of it but the maintenance of it, and that he owes her a debt he cannot conceivably repay, but which she may call in at any time.”
—Frank Pittman (20th century)
“In the planning and designing of new communities, housing projects, and urban renewal, the planners both public and private, need to give explicit consideration to the kind of world that is being created for the children who will be growing up in these settings. Particular attention should be given to the opportunities which the environment presents or precludes for involvement of children with persons both older and younger than themselves.”
—Urie Bronfenbrenner (b. 1917)
