standardized under PDI, MoPR may consider how to draw data
for NPA from LIF-PDI, as the Indicators of NPA and LIF for

PDI have both overlap and differences.
Data validation mechanisms should be based on what suits best
for that kind of data. Where additional data from the same
source used by the Ministry is to be picked up for the LIF, the
same validation mechanism already existing can be used. So, if
indicators are included in MA, the MA data validation
mechanism will take care of them. Where it is only GP and no
links to existing portals, or data source, the system like the
Bangla Paira Baithk can be used, or such other suitable
mechanism, that validates and ensures data quality.
