How to represent the anamolies in process from registration to discharge in healthcare system

I am working on patient journey process and figuring a way to map the stress points involved in the anamolies in conflict processes in the journey of patient registration to discharge. The main objective is to point out the specific process which has low performance in the entire journey. Example: when patient registered and admitted to bed. Here bed allocation process is time consuming for several reasons. I want to represent one screen with all processes but highlighting the low performance process.I would love to hear any suggestions. Thank you
