For the respondents, the total average FTE for the 11 roles described is 1.95 FTE, with a maximum per responding site of 6.5 FTE and a minimum of 0.2 FTE (from an institution in the exploratory stage).
It's also likely that some roles such as project champion, marketer, or even project coordinator may not be officially accounted for but added into the jobs of people already on staff. The programmer/ETL specialist has the highest average commitment of effort, which certainly makes sense. Note the distinction in roles and required FTE between the IT/systems engineer and the programmer/ETL specialist – while the VIVO application is written in Java, the skills required to implement a VIVO focus more on scripting and data ingest, especially after initial installation. And while a Java programmer may be more familiar with writing and deploying applications similar to VIVO, it's familiarity with the application stack (principally Apache, Tomcat, and MySQL) more than Java programming that may be required. Some implementing sites have extended the VIVO software itself for extended functionality (notably the Deep Carbon Observatory project at RPI), but most may never have to change a line of Java.
