Maintenance & Support - Reports, Charts and Tables
The following reports, charts and tables are available to you when you purchase an ISBSG Maintenance & Support Web Subscription. New reports, charts and tables are added regularly.
Charts and Tables
Breakdown of Maintenance Activity Effort
This chart can be used as a basis for planning your staffing for maintenance activities or to benchmark your maintenance activity effort breakdown.Based on 127 Applications in the ISBSG Maintenance & Support (M&S) Repository, this chart uses the Mean/Average percentage of the effort spent on the various types of maintenance activities.
Enhancement Activity Ratios
Although data in this chart comes from the Development & Enhancement repository, it is useful because in some organisations maintenence staff undertake significant enhancements. This chart shows the percentages of the total enhancement project time spent on the six activity types. Use the ratios shown in this chart to more accurately estimate effort for a large enhancement project that requires a formal development approach, and to monitor and recalibrate likely effort during an enhancement project.
Breakdown of Support Activity Effort
This chart can be used as a basis for planning your staffing for support activities or to benchmark your support activity effort breakdown.
Based on 78 Applications in the ISBSG Maintenance & Support (M&S) Repository, this chart uses the Mean/Average percentage of the effort spent on the various types of support activities.
Breakdown of Maintenance and Support Activity Effort
This chart can be used as a basis for planning your staffing for Maintenance and Support (M&S) activities or to benchmark your maintenance and support activity effort. Based on 115 Applications in the ISBSG M&S Repository, this chart uses the Mean/Average percentage of the effort spent on maintenance and support activities.
Special Analysis Reports
Managing Your Maintenance & Support Environment (Revised Report)
Two main sizing methods are used to help manage maintenance and support. Applications are either sized using Logical Lines of Code (KSLOC) or Function Points (FP). The first ISBSG report on managing M&S support environments could only provide statistics for applications sized with FP, but now we have enough applications that have been sized using KSLOC, so we have updated the report to provide that additional analysis, and we have updated our analysis for factors where the size measurement is not significant (e.g. activity effort percentages).
Maintaining and Supporting New Software Applications
In many organisations the Maintenance and Support team is responsible for the support of newly delivered software products. This report analyses software defects delivered into production by Software Development and Enhancement projects. The information in the report can be used to plan maintenance and support resources for new software deliveries and to benchmark your organisation against industry data.
