PrecisionPoint is grateful to Versapak who have now chosen PrecisionPoint’s integrated data model over other tools which build separate cubes or virtual cubes (UDM). We are also delighted that the large NAV customer, referred to in this thread, has recommended PrecisionPoint to another large food company who then actually returned their existing BI cube builder tool and traded up to PrecisionPoint. A warm thank you to PrecisionPoint customers who are happy to recommend our product and explain to other NAV customers why an off-the-shelf solution is much more cost effective and reliable than roll-you-own BI projects.
Valentin - on your point about PrecisionPoint being a closed product, all of our customers require some degree of database configuration, since no two NAV systems are the same, and changes can be made by IT, partners or, since it is typically only a few hours now and then, PrecisionPoint support desk can do it for them remotely. However all reports are created by the business users so IT is off the hook when it comes to reporting. We think that’s a good thing. So do our customers - especially IT Directors.
