In our experience you will find significant variation in capabilities, particularly in relation to the Business Intelligence and reporting. Some will be a lot more capable than others, hence price variations. We would also encourage you to consider how you hook these systems into other backend business systems - again there is significant variation in capabilities in this area. You really want your PMS to be able to pull data from a wide range of core business systems, both strategic and operational, with minimal manual intervention.
We provide solutions for sharing performance outcomes that are geographically disaggregated - they tend to focus at helping users understand spatial patterns and temporal trends. Our products can be integrated to mainstream performance management tools listed above. They are being used in performance and intelligence areas in authorities like Fife and West Lothian.
We also have an innovative performance profile scorecard that can be driven from a third party database or simple spreadsheet - you can read more about this at
