How do you decide when an Anaplan module has become too complex?

Kartik

As an Anaplan model grows, modules can gradually accumulate more line items, formulas, and business logic. At some point, splitting a module into smaller ones might make it easier to maintain, but it can also introduce additional dependencies.

I'm curious how other modelers decide when it's time to split a module rather than keep extending the existing one.

What usually drives that decision?

• Formula complexity and readability
• Calculation performance
• Different dimensionality or business purposes
• Reusing calculations across multiple modules
• Ease of maintenance and future changes

Do you follow any rules of thumb, or does it depend entirely on the model?

In Anaplan, splitting a module depends more on dimensionality, business purpose, performance, and maintainability than on the number of line items. I’d consider splitting when formulas become difficult to manage, calculations are reusable, or different dimensionality creates unnecessary cells.

Following DISCO and PLANS principles helps keep models structured and efficient. However, splitting too much can introduce unnecessary dependencies, so the goal should always be better performance, clarity, and easier maintenance, not simply smaller modules.

Hope this helps!
