Plant Section in SAP

Question

Below is SAP definition of Plant section.
Define Plant Sections (PS)
You define your plant sections in this step.
The plant section enables you to subdivide the maintenance plant from the point of view of production responsibility. The person responsible for the plant section is the contact for coordination between production and plant maintenance.
The plant section can be used for evaluation purposes.
Every piece of equipment and functional location can be assigned to a plant section.
Note
You can also specify a plant section when processing maintenance tasks.
Q1- What is the mean of " subdivide the maintenance plant from the point of view of production responsibility" ?
Q2- What we achieve by the statement "The person responsible for the plant section is the contact for coordination between production and plant maintenance."
Q3- for what tye of report or KPI it will help ?
Scenario: In on Plant Location there are 3 different lines of production , exm (JUICE, JAM and Biscuit)
For Juice line there is Filling --- Printing ---Packing  --- Out 
For Jam line there is  Filling --- Printing ---Packing  --- Out
For Biscuit there is   Backing ----- Packing ---- Out
Individual process line have individual process supervisor under once maintenance department as mechanical, electrical etc...
As per the above scenario please help me what will be the best to go for Plant section.

Answer 1

Your maintenance plant can be 1000 under which you have 3 plant sections (Juice, Jam and Biscuit lines). Individual supervisor can be the Person responsible. His role as told in the definition indicates the integration activities between PM and PP (production) modules. Like the SAP maintenance objects (Maint Order) and SAP production objects (Prod Order) can not go simultaneously or with overlaps on Equipments/FLocns.  SAP keeps provisions for industrial processes integration between funtions for fool-proofing, but many users do not make use of them. The PP work Center field given in the Location tab of Technial Objects play a role in the integration in the PM and PP processes.
At our implementation we used Plant sections as I mentioned above. 14 production lines so 14 Plant sections, but did not make use of Person Responsible field, because we have coordination outside SAP. These things have wide scope of interpretation as per their usages by different users. So wait for more expert opinions.
