SLB tried to offer all things to all customers as an integrated service company. The problem was (is) that they did not support those services properly, assigned managers that did not understand the businesses they were managing, and ultimately destroyed client relationships by replacing trusted sales and technical staff with inexperienced people whose only qualification for their new positions was their ability to meet one or more diversity targets within HR.
The proliferation of independent service providers, from pressure pumping to consulting engineering, are collectively taking away a significant portion of their respective market shares. Management sees none of it because they will not exit their echo chamber. They see only sunshine and rainbows while their lackeys blow smoke up their behinds.
Perfectly put, @OfG5JEU-djp.
