Historical benefits Method: Scope: the CBA exclusively considers time saved on tasks attributable to TFD or TFE. Effectiveness benefits, which, based on qualitative research, are the main benefits, could not be accounted for due to challenges in obtaining outcome data and the unreliability of attributing such benefits to the TFD / TFE. We opted to concentrate on efficiency for a more robust calculation, acknowledging it represents only a portion of the overall benefits. The historical benefits for both the TFD and TFE in each year are calculated as follows: - we estimated the number of hours saved per month per active users (see assumptions for time save below) - we multiplied this by 12 to have the number of hours saved per year per active users - we multiplied this by the number or active users that year to have the total number of hours saved that year (see assumptions for active users below) - we multiplied this by the monetary value of one hour of total salary cost that year (see detail below) Main caveats: Our approach uses the cost of an hour of work as a proxy for the value of benefits. However, in reality, the hours saved do not necessarily translate to fewer full-time equiv
