GNM then calculated the sum of Panaya coding and unit testing estimates per LUW, and added 25 percent effort to each LUW. Panaya estimated that it would take 350 days to upgrade the 1,100 custom objects, which increased to 537 days with the additional 25 percent effort per task.
The bulk of the technical upgrade work was delivered in 10 weeks (50 days) by six full-time developers.
While GNM recorded budget overall savings of 36 percent compared with the traditional estimate of work, Taylor said for him the key was "getting the reliable baseline with reliable estimates from Panaya".
In terms of weaknesses with Panaya's product, at the time of the GNM upgrade, some custom objects, such as OA framework customisation and personalisations, were not within its scope. These objects are now available and can be scanned by Panaya.
During the course of the upgrade project, Taylor was technical lead at GNM, employed by integrator Mokum. He is now employed directly by GNM.
