What is most valuable?
Well, I liked the split Cognos- used to have 2 differents products for reporting. One very friendly for user (query studio) and other one more for super user or tech user (Report studio).
The AdHoc reporting (query studio) are very easy with query studio but this happens only if the package is well done by the modeler. The most valuable feature in query studio is Develop/ Reduce group in a list. For Report Studio, the possibility to create report from SQL Query direct, easy, simple and efficient :)
How has it helped my organization?
We reduced IT requests for reporting and improved reports standards. High quality reports.
We used templates and reuse components so it's easy to change lots of report quickly.
What needs improvement?
Administration and security.
For how long have I used the solution?
I'm with Cognos's products since 1997. (First products I used was Impromptu, Transformer and Power Play). Last version I have used is 10.1 (Query and Report Studio).
What was my experience with deployment of the solution?
Well, developing packages makes deployment a bit long in case of emergency.
Also, for performance issues, avoid to connect the package's data on OLTP databases. Always use de-normalised databases, (ODS) or OLAP databases.
What do I think about the stability of the solution?
Server not responding some times
What do I think about the scalability of the solution?
How are customer service and technical support?
With IBM it is too complicated, I used a partner. Technical Support
With IBM it is too complicated, I used a partner.
Which solution did I use previously and why did I switch?
How was the initial setup?
What about the implementation team?
At that time I was implementing with the Cognos team and in-house. People from Cognos were very experienced.
Which other solutions did I evaluate?
I can't remember. But now I'm looking to go around looking at BI Tools to advise my customers which ones are best according to theirs needs. I will go deeper in Microsoft (for the price), Tableau for the visualisation and easy deploy and of course Cognos because it can do all BI needs (but it's expensive).
PS. Cognos Express is welcome with lower licensing price.
What other advice do I have?
If you are looking for an all integrated, scalable and high quality reporting tool, Cognos is a solution to consider. But, the price is a factor too.
You need to define well your needs for reporting, chose the right component you want to start first and start small.
