Reducing form size

The difficulty with disaggregations is that there are trade-offs to be made:

• Between the precision of the data and the time it takes to collect it

• Between having few variables with many disaggregations, or many variables with few disaggregations

Remember that because Monitool does not support disaggregated data, the size of the form grows exponentially with the number of disaggregations.

Usually, those forms are not meant to be filled by hand, but rather to be filled using the Excel data entry method, it is still important to keep them manageable. Consider forms with more than 50 fields as a warning flag and a certainty for a lot of data entry errors.

# of disaggregations	# of elements in each disaggregation	# of fields in the form for that variable
0	-	1
1	3	3
2	3	9 (3 x 3)
3	3	27 (3 x 3 x 3)
4	3	81!!! (3 x 3 x 3 x 3)
