After receiving the occupy dataset (xls), available here in more forms, three people set to work parsing through the data. Because the data was coded using SPSS, not easily human readable, everyone did a bit of preprocessing. At first this led to repeated work: using the codebook to translate individuals responses into words. After a new person arrived and those working on parsing through the data explained what they were working on it was brought to everyones attention that they were repeating some of the same work.
Now a new human readable form of the dataset has been generated.
Procedural Take Away: Multiple People working in Parallel can lead to repeated work. More sharing of process needs to occur so that things are done efficiently.
