Cognos Planning

[radekus]

Hi All,

one short question, is it Cognos Planning similar with Cognos TM1 ?
Can you explain it ?

Sorry for my newbie question.

Thanks.

Hi Radekus,

Yes, Planning and Tm1 are very similar.  Rather than re-invent the wheel, this question has been asked a number of times from the looks of a quick search on google:

This one is a little difficult to following due to some language barriers I believe: (read the entire thread as there are some corrections to read in later posts)

As a member of the website LinkedIn, I'm a member of a group where a guy by the name of Mitch put together a very nice advantage / disadvantage list:

Advantages:

1. TM1 stores data in RAM on the application server versus reading and writing data to a database. This results in faster processing of data.
2. There are no limitations with cube size in TM1.
3. Because of the unlimited cube sizes, TM1 models generally have fewer cubes than Cognos Planning models.
4. No more "Go To Production" or "Synchronization" processes - changes are updated instantly.
5. Publishing data - The built-in reporting that comes with Cognos TM1 reads directly off of the data in the TM1 cubes. There is no need to publish the data first. TM1 cubes can be selected directly as data sources in Framework Manager providing closer to real-time reporting.
6. Contributor applications - You will probably have fewer models in TM1, with no admin links or system links to maintain.

Disadvantages:

1. The biggest disadvantage to using TM1 is in the model design functions. TM1 is very keyboard oriented, as opposed to Cognos Planning, which is mouse oriented. For instance, when creating d-links in Cognos Planning, you can visually see the dimensions being matched up. In TM1, however, a rules engine is used to bring data from one cube to another. The rules resemble lines of code that programmers use. Using rules instead of d-links requires a lot more work to understand the logic that brings in data from one cube to another.
2. Customers who convert to TM1 will most likely become more dependent on outside consultants to design and maintain their models. In addition, accountants and financial analysts who administered their own Cognos Planning models will probably need more assistance from their IT departments with TM1.
