Documentation or archival analysis is rarely used as the sole technique
in field research, but it is almost always used to supplement other techniques. It is
also collected as a means of triangulation (Hatch, 1997). The documentary acts as a
source of theoretical sensitivity. Strauss and Corbin (1990) explain that theoretical
sensibility involves “having insight, the ability to give meaning to data, the capacity
to understand, and capacity to separate the pertinent from that which is not. ”
