The total ranking of a product, represented by the bar length, is based on a weighted aggregate score. The score is calculated as follows: The product with the highest count in each area gets the highest available score. (20 points for Reviews; 16 points for Views, Comparisons, and Followers.) Every other product gets assigned points based on its total in proportion to the #1 product in that area. For example, if a product has 80% of the number of reviews compared to the product with the most reviews then the product's score for reviews would be 20% (weighting factor) * 80% = 16. For Average Rating, the maximum score is 32 points awarded linearly based on our rating scale of 1-10. If a product has fewer than ten reviews, the point contribution for Average Rating is reduced (one-third reduction in points for products with 5-9 reviews; two-thirds reduction for products with fewer than five reviews). Reviews that are more than 24 months old, as well as those written by resellers, are completely excluded from the ranking algorithm.

What is most valuable?

The GUI interface is nice and easy to use. The only complaint is around the organization of the icons as they are not saved across users. All the items are grouped together and you have to separate them.

How has it helped my organization?

The product had many issues. We had great collaboration with the product development team, but the product was not able to meet our 10 second refresh requirements.

What needs improvement?

The aggregations were not always being picked up by Tableau. There was also an issue with the incremental aggregation not working as indicated.
