Survey Analysis Grows Up with SurveyVisualizer

Luc Girardin of Macrofocus contacted us in response to our post "When Will Survey Analysis Grow Up?" to point us to their SurveyVisualizer analysis tool. I had a little time this weekend to download and play with this application. There is a lot to like.

SurveyVisualizer is designed for surveys that have a hierachical or tree structure. Luc describes the relevant data structure in a background paper about the product:

The questions—also called quality criteria—are then aggregated into 23 quality dimensions (e.g. network quality, ticketing, cleanliness, security, reliability). They represent the level of satisfaction with a whole group of questions pertaining to a particular issue. The quality dimensions themselves are further aggregated into three different customer satisfaction indices, reflecting the different areas of responsibility.

The free download has multiple satisfaction "criteria" (e.g. friendliness of crew) roll up to "dimensions" (e.g. cabin crew) which fall under "indices" (e.g. index of flight services). This may be an appropriate structure for a satisfaction survey—but it isn’t one I’ve encountered before.

Despite this limitation, the analysis capabilities delivered by SurveyVisualizer are intuitive and innovative. For example, all your survey data is displayed at once in a kind of relational map. This lets users visually identify patterns in the full set of results. Each of the vertical hashes represents a question or roll-up of questions. Clicking on any one of these hashes highlights the hierarchical relationships. The "ghost" lines represent the results across questions for a multitude of dimensions or respondent types.

Users have the ability to select specific dimensions to identify patterns in the corresponding results. An easy-to-use interface lets you choose a dimension then apply a color to the line within the relational map.

Also, users can click on individual display lines to investigate the results (e.g. I wonder who had that particularly crappy score for flight delays?)

If your analysis requirements don’t fit this particular structure, Macrofocus has a more general-purpose tool called InfoScope.
