ABSTRACT
This chapter uses the thinking process (TP) tool, the "Future Reality Tree (FRT)," to answer the question of theory of constraints (TOC), "What to change to?" If an undesirable effect (UDE) indicates a negative effect in a Current Reality Tree, its logical opposite, a desired effect (DE), indicates a positive effect in an future reality tree (FRT) and tells us what to change to. The chapter discusses the study of half-baked solutions and the Negative Branch Reservation (NBR). A half-baked solution is a solution whose consequences have not been thought through completely. The entities of the FRT must be scrutinized using NBR. The development of a positive branch must be accompanied by a NBR analysis. The positive loops which we usually find in an FRT need to be sustained. Before taking any action, if we study the many possible consequence branches, we can avoid any potential negative consequences and find some actions which can reinforce the positive consequences.
