[quote userid="63692" url="~/discussions/f/process/24999/maximum-limit-of-nodes-in-process-model/146856"]ok thank you. I guess there is a hard limit of 30 chained nodes correct?[/quote]

Chaining node limits are defined in custom.properties and this is set to 50 by default.

Appian suggest not to use more than 30 nodes

Hi vinothkannar , On a short note - There is no strict limit for this, but according to best practices, the recommended number is 50. We can add as many nodes as needed, but doing so may raise warnings or performance issues due to the large process, and we would have to manage those consequences. That's why, as per best practices, the ideal number is 50, and we are splitting the tasks into subprocesses.

AFAIK there are no hardlimits on the number of nodes. Best practices recommend keeping nodes under 30 to maintain performance. If there is any hard limit it may be because of activity-chained sequences, like if you have a chained process flow, it cannot exceed 30 nodes Beyond this limit, the activity chaining will break, and users may experience delays.

Best practice is to create short lived process models (not more than 30 nodes).

I got a hard limit at 50 on my last project

The PM that goes over 50 nodes could be practically unusable. Many of us have made PMs that have 2. Start and End. An ideal average would probably be somewhere between 5 and 10.

Ask yourself why the switch from recommending less than 50 to recommending less than 38 would be of concern, and if that doesn't point to something more concerning. Just because you can doesn't mean you ever should.

Just repeating the same core message in other words:
Not just something is technically possible means automatically you should do it.
Best practices are giving guidances how to solve certain situations the most suitable way.

As with all of the Best Practices and Guides they are not hard limits, but guidance. You always have to consider the context in which you're considering these values, and have an understanding of why such limits are even being suggested. You can then make risk-based decisions as to whether you need to address the recommendations or not. Because, in the end, it's about risk management: the likelihood, and the impact, and what (if any) mitigations you choose to apply.

I obtained it via consulting design guidelines and best practices. vex 5

yes ..i got it from best practices and design guides. Thanks!

AFAIK there is no hard limit, but best practices and design guides.

May I ask what your concern is?
