We've definitely seen an ROI. It's been worth it for us.

We did not achieve the ROI. The work delivered to users had lesser value than the subscription cost.  

It helps organizations get better business efficiency and ROI in their heterogeneous environment.

No ROI for us. The company I work for has no business approach to BI strategy. All we, as a company care, is to make the customer happy and that has the cost of not letting us turn down some unprofiting projects. So, Pentaho is a good tool and capable of delivering millions of dollars on new/recouped/saved revenue, but we are not posing for that.

Thinking a bit more, the mere fact we are able to deliver more, and hence take more orders, might be seem as a return on our investment. Yet I can't exact a number, for even this kind of return is a little unclear.

The ROI of this product is good, because in little time you can have the first’s outputs. But it’s not excellent if compared with other BI solutions, like QlikView or Tableau.

It's difficult to predict the ROI as it was just a component of the system.

45%

Decrease of development time compared to our traditional development cycles in pure Enterprise JAVA solutions should be estimated around 60%.

Awesome. Even for enterprise edition. Obviously much better for community version.

Government Project, so did not do ROI for this, just KPI.
