Unidata Support

Above are histograms that portray the number of Unidata email responses for categories of support for a one year period ending May 14, 2004. The histograms are arranged by yearly activity averages with the highest on the left and lowest on the right. Each quarter year within the period is depicted from oldest to newest from left to right. The number of responses has been normalized to weekly averages so that the support load over the various periods can be easily compared.

Total support averaged 120 responses/week over the entire year; 124 for the first quarter; 123 for the second quarter; 106 for the third quarter; and 126 for the current quarter.

Individual support activities included in the categories shown above are listed in the following table.

Comments

• As anticipated in previous reports, LEAD support is growing.
• Support numbers for individual packages, groups, and lists can be seen in full support statistics.

Some tentative conclusions

• The total support load for the UPC remains high and varies seasonally.
• Support required for the legacy visualization packages (GEMPAK, McIDAS) continues to be substantial.
• Support required for LDM, IDD, and data continues to grow slowly but shows variability throughout the year.
• Support for netCDF and outreach remains high.
• Taken as a whole, the support required for visualization packages (GEMPAK, IDV, and McIDAS) is comparable to the support required to receive data (LDM, IDD).
• Support for any package increases after a new version of the package is made available.

NOTE

These numbers and conclusions should not be taken too literally, for several reasons:

• For some packages, multiple responses in the same thread may be bundled into a single archived email. Other packages have each response in a thread counted separately.
• After a new release of software, there may be a flurry of the same or similar questions, which can be answered in separate emails or in a single mailing list posting.
• This counts primarily support of end users and site administrators, not developers. Support for other developers in projects such as OPeNDAP/DODS, THREDDS, McIDAS, GEMPAK, and IDV requires significant resources, but is difficult to assess.
• Not all support records were indexable for this report. Given this, the above numbers are an underestimate of the actual support being provided by the UPC.
