The questions from the survey break down into five categories: Developers, Documentation, Performance/Functional Aspects, Appearance, and Ease of Use/Learning. A good place to start analyzing the results is with questions related to developers, since this is where most websites begin. Documentation questions are grouped with these because developers rely upon documentation to answer questions or explain problems that may arise. Taken together, questions about developers and documentation give us a sense of what types of web development projects each CMS is best suited to.
We have updated
our pdf file containing the results from our Drupal vs Joomla survey. Updates since our original pdf include: 1) a Table of Contents, 2) an introduction, 3) additional questions 4) explanation of Average Budget, and 5) enhanced graphics.
We have compiled the results of the Drupal vs. Joomla Survey into a number of tables. There is more information than can easily be displayed in a blog post. For this reason we have provided the Joomla vs. Drupal Survey results in a PDF File. The PDF contains cross-tabs of each survey question by CMS the respondent is most familiar with. In other words, for each question you'll see responses from Joomla Users, Drupal Users, and All Users. For those interested in looking under the hood we have also provided a CSV file of the raw survey data. All identifying information has been removed.
The raw data is intended for people who would like to do their own statistical analysis of the survey. If you use this data we request cite us as the source and link to our website.

We are pleased to announce the conclusion of our Joomla and Drupal comparative survey and would like to thank everybody that participated for your help on this important issue. We were able to collect over 190 surveys and believe that with this help we will be able to provide an updated view on the benefits and tradeoffs with each CMS.
There are several good comparative reviews of Joomla and Drupal available on the internet. However these reviews are often out of date and fail to quantify the tradeoffs involved in selecting one CMS over the other. We are asking professionals familiar with these content management systems to take a survey about the relative strengths and weaknesses of Joomla and Drupal.
Our survey research will update the analysis of these two content management systems, provide a more rigorous basis for evaluation, and quantify the tradeoffs. We hope this will lead to a better understanding the tasks to which each CMS is best suited.
