There's new competition, but Anaplan still delivers

Anaplan is interesting because it is at the same time easy to use and difficult to use. An end user can navigate a well-constructed app, being pointed in the right direction every time they feel a slight bit of confusion, and find everything they need in what feels like a straight line. Similarly, a model builder (developer of sorts) can have the exact same experience, but the journey is longer and more complicated. End users have great experiences with Anaplan, but sometimes model builders have a frustrating one. That is not to say model building is hard (because it truly is not), but things change, and when things change in complex systems, the effort required simply to investigate where a model builder needs to make an adjustment may frustrate them but also frustrate their non-technical bosses.
However, the reality is that with complicated businesses, complicated business problems, come complicated solutions. It is actually a testament to Anaplan's capabilities that it has taken on the biggest problems at the biggest companies. It may be daunting to adjust it in those environments, but at least you know it did meet the needs there, which is more than most tools can say.

Anaplan is a great tool for complex modeling of the future. When you are planning your actions for the future, have multiple, disparate datasets to interact with, have dozens if not hundreds of stakeholders who must contribute and need to be guided via a streamlined workflow engine, require complex logic that can grow with your org, require real-time reporting, and you need it all in less than 6 months.
