The amount of time required to complete an SFD Report will depend on the Level of study you develop, the amount of data available and your access to key informants. During the piloting of our methods we found that a desk-based study (roughly equivalent to an Initial or Intermediate Level SFD Report) took between three to five weeks and a field-based study (roughly equivalent to a Comprehensive Level SFD Report) took up to two months. Where you are familiar with the town or city being studied the time involved is likely to be significantly shorter. It was also found that significant additional time may need to be factored in for stakeholder approval of the final SFD report.
