Last Thursday, I posted an interview with the author of the new TM1 book Karsten Oehler. Here is the continuation of the conversation. This part of the interview focuses on the new IBM Cognos TM1 10.1 release.
Christoph Papenfuss: IBM Cognos TM1 10.1 was released in February of 2012. What is so special about this release?
Karsten Oehler: One of the central components of version 10.1 is a new modeling environment. It is called Performance Modeler. It really encourages finance and business professionals to develop their own models. Performance Modeler allows them to develop complex rules and links. You can also easily import data into applications. None of this requires deep technical knowledge.
Christoph Papenfuss: Does Performance Modeler replace Architect?
Karsten Oehler: Performance Modeler is an enhancement. The user can choose which tool to use. Architect is closer to Excel and has some features which are currently not supported by Performance Modeler. This includes dynamic subsets and report generation of Excel sheets from the cube viewer.
Christoph Papenfuss: There is a new desktop tool call Cognos Insight. It looks similar to TM1. Is there a relationship or connection between the products.
Karsten Oehler: Cognos Insight is a very powerful desktop tool that allows business people to conduct analysis, explore data and to develop prototypes. TM1 and Cognos Insight are closely connected – a local TM1 engine is part of Cognos Insight. It uses the same rule syntax and a simplified Turbo-Integrator version for data import. You can also import Cognos Insight models into Performance Modeler and refine them further.
Christoph Papenfuss: What is the advantage of using Cognos Insight in the planning process along with TM1
Karsten Oehler: There are two aspects: Planning applications are often created by prototyping. Cognos Insight is a great tool to express ideas and to develop prototypes. Secondly Cognos Insight can be used an additional front-end for contributors to the planning, budgeting and forecasting process.
Christoph Papenfuss: Who should use Cognos Insight as a client for planning and forecasting models?
Karsten Oehler: TM1 has strong tools to support a highly decentralized planning and forecasting process. I recommend to use the IBM Cognos Contributor front-end because it is easy to distribute (non-local installation). With TM1 10.1 you can also integrate web sheets created via the Excel add in. However if somebody is using Insight for data discovery it is very interesting to contribute to the planning process directly within Cognos Insight. Another advantage is the scalability: With Insight it is possible to let the local insight engine do all the calculation which is needed for the planning slice assigned to the user.
Christoph Papenfuss: What do you like best about TM1?
Karsten Oehler: It is definitely the rule language. It is the most compact way to formulate all kinds of calculations to solve all kinds of business problems. The most complex cost and profitability calculations often look pretty easy after modeling them with TM1 rules.
Christoph Papenfuss: Thank you so much, Karsten!
