Implications of census approach Implications of sample approach

• Data collection becomes part of regular business. Staff

may need to take on extra responsibilities

• Initial costs (training and any IT changes) may be high,

but these will generally reduce over time

• All staff to be trained initially

• Staff ownership – should be seen as business as usual

• Continuity – High chance of continuity

• Robustness – more robust for trend analysis

• Data management can be overwhelming at the

beginning, but should become easier over time as

process is embedded into operations

• Project management should be smoother and become

easier over time as this process becomes business as

usual. Only small changes may be needed over time

• The effectiveness of a census approach is high as data

collection and processes are business as usual

• Separate time allocation for data collection which can be

inefficient.

• Generally each sample data collection approach will

cost the same over time.

• Only a few staff to be trained – loss of these staff may

require further training in the future

• Staff ownership – may be seen as separate activity and

therefore less ownership taken

• Continuity – easier to stop

• Robustness – Less robust for trend analysis

• Data management may be easier with smaller amounts

of data

• Project management can be difficult it requires effective

resource allocation and constant attention.

• The effectiveness of a sample approach may be low to

moderate as the data collection is a separate activity
