Problem management is the dominating process within corrective maintenance. It not only handles software problems but also provides quantitative feedback important for assessing product quality, crucial for continuous process analysis and improvement and essential for defect prevention. Chapter 2 gives a detailed description of the problem management process and its constituent phases, activiti...

To estimate the corrective software maintenance effort, it is critical to know the factors that are most influential to the productivity of corrective maintenance activities. In this study, we analyzed activities and productivities of correcting 810 defects in one Norwegian software company and 688 defects in another Norwegian IT consulting company. We compared the profiles of defects that are ...

We establish the context of maintenance outsourcing of mission critical applications by Fortune 500 organizations. We present the results of empirical studies that were conducted at Syntel, a NASDAQ listed application management and e-business solutions company, on 46 software maintenance projects that belonged to various lines of business on the IBM mainframe platform using an automated data c...

Software maintenance involves different categories of activities: corrective, adaptive, perfective, and preventive. However, research regarding these distinct activities is hampered by lack of empirical data that is labeled to identify the type of maintenance being performed. A promising dataset is provided by the more than 800 versions of the Linux kernel that have been released since 1994. Th...

To estimate the corrective software maintenanceeffort, we must know the factors that have the strongestinfluence on the effort of corrective maintenance activities.In this study, we have analyzed activities and effort ofcorrecting 810 software defects in one Norwegian softwarecompany and 688 software defects in another. We comparedthe defect profiles according to the def...

In 1978, Lientz, Swanson, and Tompkins published the results of a survey on software maintenance. They found that 17.4% of maintenance effort was categorized as corrective in nature, 18.2% as adaptive, 60.3% as perfective, and 4.1% was categorized as other. We refer to this result as “LST.” We contrast this survey-based result with our empirical results from the analysis of data for the repeate...

Most companies register a large quantity of information in their maintenance data bases, but this is often poorly exploited. An efficient valorization of a maintenance history can improve future maintenance strategies. In maintenance optimisation, four general types of maintenance strategies are taken into account such as: a) corrective, b) preventive, c) predictive, and d) reliability centered...

-From the preliminary stage of software engineering, selection of appropriate enforcement of standards remained a challenge for stakeholders during entire cycle of software development, but it can lead to reduce the efforts desired for software maintenance phase. Corrective maintenance is the reactive modification of a software product performed after delivery to correct discovered faults. Stud...

Even though many approaches have been proposed for automated fault detection and diagnosis of Heating Ventilation and Air Conditioning (HVAC) systems, and advanced maintenance programs, such as preventive and predictive maintenance have been applied for the systems, issuing work orders for corrective maintenance is still a reality. Currently corrective maintenance still accounts for more than 5...

Many process models have been hitherto suggested. Very few of them, however, deal with the most utilised process today – the maintenance process. In this paper, we present and motivate the “Corrective Maintenance Maturity Model” (CM 3 ) a process model entirely dedicated to only software maintenance. .
