Do not collect more information than you need. What are you looking for? You should define it rather narrowly. The scope should not be too broad.
What results do you want from the programme?
You need to know what each element of the programme is supposed to provide or achieve. Which skills should be developed by the programme?
Are you collecting the data properly?
There are many data-collection methods. Each one has its own purpose. A change in behaviour can be well recognised by a 360-degree assessment. Focus groups, on the other hand, will provide a deeper understanding of what makes it difficult to implement in practice the behavioural changes that are required.
