All businesses, at their principal core, are essentially people businesses! 

On a side note, it's pertinent to highlight a wonderful quote from quality guru W Edwards Deming: 

"94% of problems in businesses are systems driven, and only 6% are people driven."! 

He added: 

“Any substantial improvement must come from action on the system, the responsibility of management. 

Wishing and pleading and begging the people to do better was totally futile.”!
