Flexibility: It offers a variety of technical solutions to better satisfy each customer’s needs and scenarios.
IBM Cognos BI (version 10) is a suite of different modules for reporting and analysis:
Each of them is perfect for a specific need.
For the metadata modeling activity, as well, Cognos offers several modeling tools:
Depending on how much data has to be analyzed (or other factors), the modeler will decide which modeling tool to use.
I’m a freelancer; I am a consultant. I’ve helped hundreds of customers to better understand their business and to make better decisions.
I think IBM Cognos BI solution needs improvements in:
1) chart quality: many other competitors have charts and graphics that look much better and that provide dynamic effects. Cognos doesn't.
2) data source connections: many other competitors support connections to cloud and innovative data sources (Google Analytics, Facebook, Microsoft Azure, MongoDb, Microsoft Dynamics CRM, Microsoft SharePoint and so on), that IBM Cognos BI cannot connect to.
3) maps: IBM Cognos BI have only 35 predefined maps. If you need a map of a particular area, you need to buy it (in MapInfo or Esri formats) and convert it in Cognos format, and this is pretty a long way. Furthermore, it's very inconvenient to use Google Maps maps, since this kind of integration is not native.
I sometimes encounter stability issues, but they’re rarely really issues.
I have never encountered any scalability issues. The product easily scales very well.
I would rate technical support between 2 and 3 our of 10. Several times in the past, I have needed the help of IBM official technical support, and there was more lost time than any actual contribution received. The IBM technical support people often know IBM products less than I do. So, nowadays, I no longer make use of technical support; it’s almost always useless. This means I do not waste a lot of time for no reason.
I’ve always used this solution.
When I initially studied the IBM Cognos software, it was not so easy to fully understand, but now all in all it’s not so complex.
I did not evaluate other options before choosing IBM Cognos.
In the last weeks I'm having a look to Tableau Software.
Be sure you have an expert Cognos consultant before starting.
