There is a very simple way to create an OS X 10.11 El Capitan installer.
You need the full installer of OS X 10.11 El Capitan and a USB Drive (or something similar)
 
 
OS X 10.11 El Capitan has an executable file createinstallmedia to make a bootable usb.


Command to make an external OS X 10.11 El Capitan installer
This is assumes you have a an external partition named "YOURVOLUMENAMEHERE” (You should probably change your volume name)
Make changed where appropriate

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/YOURVOLUMENAMEHERE/ --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app/ --nointeraction

2. Type in your password (Assuming you are an admin)
3. You will see the following:

Erasing Disk: 0%... 10%... 20%...100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.

System Integrity Protection (SIP)

Apple has implemented a new security feature in 10.11, System Integrity Protection, which prevents even super users from altering the contents of files in key System folders. The flags for restricting the folders is applied at the time of installation and cannot be overridden. SIP is designed to protect System files from malware and viruses. 

Disabling SIP requires booting into the recovery partition to run the Terminal command below.

# csrutil disable

which should confirm with status message:

Successfully disabled System Integrity Protection. Please restart the machine for the changes to take effect.

Reboot back into the El Capitan system partition.  

To re-enable SIP, boot back into the recovery partition and set state to enabled:

# csrutil enable

Many organizations are moving to a MDM server for both shared use and one to one iOS devices. If you plan on assigning organization-owned apps to those devices, you will need to be a member of Apple's Volume Purchase Program and purchase both zero cost and paid apps from the VPP store, selecting managed distribtuion as your license type. Organizations that had previously purchased VPP apps with redemption codes that were largely used for Apple Configurator-based deployments need to request migration as per the instructions in Apple's support article https://support.apple.com/en-us/HT202863.

If, after migration, apps appear as only numbers with "B2B" next to them and you do not have any enterprise-owned apps in your distribtuion list, the cause is likely that the app is no longer available in the (iOS/iTunes) App store.

System Information, and the plethora of information about your Mac computer that you can obtain from it, can also be accessed from the command line using the system_profiler command. By default, it outputs all information directly to the screen, so you may want to redirect the stdout to a file.
