Customize OOTB form at SPM or create a new form from scratch

[MatthildiP]

Dear all,

I have a dilemma. A client's business requires managing information and the lifecycle of some entity that resembles a project, but isn't exactly a project.
What's better? To add 200 new custom fields with embedded workflow to an OOTB form or to create a custom form?

Thank you

Kind Regards

thank you very much!!! 

The first idea with the related records is very valid and i will use it. 

Can you please send me some reference regarding your idea for the Playbooks? It is also very interesting..... 

Thank you again!
