In some ways, the production version of DataClean (NameClean) is much better than the beta. It's clear that RM listened and tried to address usability problems that users discovered in the beta. Nevertheless, I think the production version has its own set of problems in the user interface.
First of all, I'm so incredibly pleased that DataClean (NameClean) supports Named Groups. One of the biggest problems with the beta was that it would only operate on the whole database, which for many databases was far too many individuals for a user to deal with at the same time. On the other hand, the beta made it very easy to look at one person at at time; to accept, to reject, or to modify RM's proposed cleaning; and to proceed quickly to the next person. The user interface for the production version has made this latter process very awkward and extremely clicky.
Here's what happens. Suppose a suggestion comes up that you want to accept (the most common case). No longer can you just click an "accept" button that is located nearby the suggestion that you are looking at. Instead, you have to click a check box in a list of names that is far removed on the screen from where the suggestion is located on the screen. You have to move your eyes to find the place to click. Then, having clicked your approval the cleaning process does not automatically advance to the next person as it did in the beta. So you have to click again on the person just below the person you just approved to advance to the next person. Finally, you have to reorient your eyes again much lower on the screen to see the next suggestion. The failure to advance to the next person automatically is certainly very unfriendly, but I think the continuous reorientation of the eyes is even a worse problem than the extra clicking to advance to the next person.
In the case of the beta, any NameClean suggestions you approved were applied immediately. With the production version, any suggestions you approve are saved up until the end and you apply all the approved changes at once. For the time being, I'm reserving judgement on whether this aspect of the user interface is better or worse than the beta, or just different..
In summary, the support of Named Groups is a huge improvement over the beta. The extra clickiness and especially the extra eye movements are several steps backard from the beta. And it's not clear whether delaying the application of approved changes till the end is an improvement or a step backward as compared to the beta. Finally, one of the needed improvements identified in the beta process was the ability to edit the person for whom the suggestion is being made or otherwise to be able to see the person in context (parents, children, spouses, etc.). With some of the NameClean suggestions, this would be important information to know before approving or modifying the suggestion. However, the production version of NameClean did not address this issue.
