You’re Building Blind: Why Your TM1 Model is Too Complex (And How to Fix It in 10 Minutes)

Can You Answer This? The Question that Exposes TM1 Complexity 

"Can you quickly explain how this model works?" 
If that question makes you break into a cold sweat, that's a telling sign. 

In our first post, we covered TM1 documentation challenges and its hefty costs. This post delves straight into the deeper cause: unchecked TM1 complexity. 

Last month, a senior TM1 developer admitted: 
"I built this allocation model two years ago, and honestly, I'd need a full day to re-understand how it works." 

That wasn't a confession of incompetence, it’s what happens when complexity goes unmanaged. 

The uncomfortable truth:  
If you can't quickly explain your TM1 model to a colleague, it is too complex.
That complexity is what will cost you time, money and control.

TM1 Complexity Assessment: Get Your Score in 2 Minutes 

Before you can reduce complexity, you need to measure it. 

Our TM1 Complexity Assessment evaluates the maintainability and risk of your model across 5 critical dimensions: 

1. Cube Count: How many cubes are in your model? 
2. Dimension Relationships: How extensively are dimensions shared across cubes? 
3. Rule Complexity: What’s the density and depth of your cube rules? 
4. Feeder Relationships: How optimized are your feeder statements? 
5. Process Dependencies: How fragile are your TI process chains?

The Bottom Line for TM1 Developers 

Model complexity is not a badge of honor. It’s technical debt that grows silently. 

Every added layer makes your models: 

• Harder to modify 
• More expensive to maintain 
• Riskier to use 
• Impossible to hand over 

But here’s the good news: you’re not stuck. 
You don’t have to be the only person who “knows how it all works.”  
 
With Omni, complexity becomes something your whole team can manage together. 
With instant visibility into your TM1 architecture, your team can build, troubleshoot, and collaborate with full confidence.

Because in TM1 development: 
What you can’t see clearly, you can’t manage effectively.
