In Kurt Vonnegut’s 1993 play “Make Up Your Mind,” the character Roland Stackhouse invents a therapy for people who have trouble making decisions. Vonnegut was all too familiar with the syndrome. He wrote several drafts of the play but was unable to settle on a final script. One version was briefly staged in 1993 and then consigned to a drawer with 11 other variations.

Now, six years after the novelist’s death, a new adaptation of “Make Up Your Mind” by the playwright Nicky Silver is scheduled for November at the SpeakEasy Stage Company in Boston.

Some Vonnegut fans may be unaware that the author of “Slaughterhouse-Five,” “Cat’s Cradle” and “God Bless You, Mr. Rosewater” wrote for the theater. One reason may well be the writer’s indecisiveness. “I don’t think Kurt was ever happy with any final version of any play he wrote,” said Donald C. Farber, Vonnegut’s longtime friend, lawyer and literary executor.
