A full GT study will produce a theoretical account of a situation that is grounded in the data, is saturated, and is suitable for wide scale testing. So GT can "explain why happened, predict what will happen and interpret what is happening in an area substantive or formal enquiry" (Glaser, 1978, p. 4).
