Changing Documentation involves changing the participants' manual. For example, one might wish to change the currency used for the simulation (from Dollars to Euros) or, as was the case for the Company Version change the names of the products and market sectors. Changing Documentation is a cosmetic change and the simulation software is unchanged Commonly it is enough to ensure verisimilitude as was the case for the Company Version and. occasionally. this may all that is necessary (although it may need to be done with changing terminology).
