Albert Einstein? A Yale Professor? Apocryphal?

Question for Quote Investigator: The importance of laying the proper groundwork before attempting to solve a problem is emphasized in a popular statement that is usually attributed to the scientific luminary Albert Einstein. Here are three versions:
If I had only one hour to save the world, I would spend fifty-five minutes defining the problem, and only five minutes finding the solution.
If I had an hour to solve a problem I’d spend 55 minutes thinking about the problem and 5 minutes thinking about solutions.
Given one hour to save the planet, I would spend 59 minutes understanding the problem and one minute resolving it.
Because there are so many different variations I do not have much confidence that this was actually said by the acclaimed genius. Would you please explore this expression?
Reply from Quote Investigator: There is no substantive evidence that Einstein ever made a remark of this type. It is not listed in the comprehensive collection “The Ultimate Quotable Einstein” from Princeton University Press.1
The earliest relevant evidence located by QI appeared in a 1966 collection of articles about manufacturing. An employee of the Stainless Processing Company named William H. Markle wrote a piece titled “The Manufacturing Manager’s Skills” which included a strong match for the saying under investigation. However, the words were credited to an unnamed professor at Yale University and not to Einstein. Also, the hour was split into 40 vs. 20 minutes instead of 55 vs. 5 minutes. Boldface has been added to excerpts:2
Some years ago the head of the Industrial Engineering Department of Yale University said, “If I had only one hour to solve a problem, I would spend up to two-thirds of that hour in attempting to define what the problem is.”
Albert Einstein died in 1955, and by 1973 a version of the saying had been assigned to him in an article in the journal “Invention Intelligence” based in New Delhi, India. Interestingly, the hour was split into three parts instead of two. No supporting data for the attribution was given:3
Often the problem as given is misleading, and you have to work through a mass of data to define the real problem. Often this step consumes more time than deriving the solution. Einstein said: “If I were given an hour in which to do a problem upon which my life depended, I would spend 40 minutes studying it, 15 minutes reviewing it and 5 minutes solving it.”
