Length of involvement
It seemed possible that projects with different lengths might have different characteristics, and the sample provides a large range of these. The median amount of time spent was 4 years, but one participant worked on the materials for 16 years, and four others worked on their materials for only one year.
When the projects occurred
Given that this study seeks to raise issues in the field, it seemed necessary for at least some of the projects to have happened recently, so the years in which projects were happening were charted. The table below shows how many of the projects in the study were happening in a given year. Some projects happened over a period of years, so they were included in the totals for each of the years that they were occurring. The chart shows that a healthy portion of the materials creation work was recent. None of the projects analyzed were more recent than 2016 because the interviews were conducted in 2016.
