Although I searched fairly extensively, I couldn't find any references as to the origins of pre-plan. According to Online Etymology Dictionary, pre-arranged and prearranged have existed since 1792 but it fails to mention the history of pre-plan.
Dictionary.com which is a reliable source for dates and examples of usages, doesn't even list the verb. Instead it re-directs the reader to plan
Oxford Dictionaries (which rarely provides the origins of words) says
pre-plan
[WITH OBJECT] (usually as adjective pre-planned)
Plan in advance: Safety and security of supply demand that they operate to stringent standards and create a mindset that is preconditioned towards conformity and pre-planned behaviour
Collins Dictionary notes the one word solution:
preplan
But then he added, `We'll let the company treat us, and I'll tell you all about how to preplan and prefinance your mother's funeral.
- Exactly how old is this "corporate speak" expression?
- Is it really derived from the world of business?
- Has its meaning evolved or changed during the years?

The two earliest instances of preplan/preplanned/preplanning (with or without a hyphen) that a Google Books search finds are from the pen of Robert Southey, who was Poet Laureate of England for the last thirty years of his life (from 1813 to 1843). The first instance is from a letter by Robert Southey to the Reverend Neville White, dated February 19, 1824, reprinted in Selections from the Letters of Robert Southey (1856):
The next is a quotation from Robert Southey's "Colloquies on the Progress and Prospects of Society," in a review of that work in Blackwood's Edinburgh Magazine (October 1829):
From "Shakespeare in Modern Thought," in North American Review (October 1857):
From "Long Vacation," in London Society (January 1868):
From John Scott Russell, Systematic Technical Education for the English People (1869) [the same year as the New York Court of Appeals Decision cited in bib's answer]:
The origin of the word preplan thus appears to rest not with an anonymous twentieth-century purveyor of business jargon, but with a nineteenth-century poet and litterateur; and other early instances of the phrase show its being taken up in the fields of literary criticism, memoir, pedagogy, and law. The modern notion of convening a preplanning meeting before the planning meeting to work out what will be covered and (perhaps) decided at the latter may be a creature of corporate or government bureaucracy; but preplanning itself evidently was not born in a conference room.
With a confirmed first occurrence Google Books search results of 1824, preplan actually beats the earliest confirmed match for the phrase "plan ahead"—which has its own problem with face-value redundancy, and which has a confirmed first occurrence of 1848 in Google Books search results. I see very little change in the sense of preplanned from its meaning as used by Southey in the 1820s and its meaning as given by Oxford and Collins and quoted in Mari-Lou A's question.
