VMware Appliance Marketplace Ratings Analysis

with 2 comments

During the past week, I was analyzing the recently revamped VMware Appliance Marketplace. My analysis is summarized below:

Salient Statistics

  • 9% are top-rated, i.e., have a Star Rating of 5
  • 41% have a Star Rating of between 3 and 4, i.e., this cluster may be providing the most value to its users, even though it is not top-rated.
  • There is a steep drop-off in the number of appliances that have a Star Rating below 3
  • 31% are unrated, which seems to indicate that a significant majority has been submitted recently
  • Only 3% (40/1227) have Reviews – this is a very small number. The number of reviews have to grow substantially to indicate that a vibrant community, like Amazon.com reviews, has formed here

Transparency

I feel there is a greater need for transparency. What do the Star Ratings mean?

  • Are they correlated with the number of downloads for that appliance?
  • What is the impact of reviews on these ratings?

Beware Star Ratings alone! The following appliance rated 4.5 has 4 reviews, read them and you will know what I mean.

As a member of VMware’s Technology Network community, I will urge VMware to provide greater transparency around how these ratings are computed/awarded. It will greatly help the users understand the ratings system.

What do you think?
