There are a few things to try when dealing with long-term data collection efforts. First, if you can automate it, go for it. This is not always an option, but it never hurts to ask. The next step is to ask the data collectors if they’ve got ideas for short cuts or time saving methods. Sometimes people get the impression that the data collection method is set in stone so you should reach out if you have not. And lastly, engage the data collectors in the results of data collection. Arrange to share results with them so they can appreciate the fruits of their labor.
