The power of these
processes is: firstly, in their ability to make the user think through clearly
what they know and do not know, secondly to be able to communicate the users
thinking to others in a way that they can contribute effectively, and thirdly,
to develop simple solutions that the correct people can implement quickly, that
realise rapid large lasting benefits and which are at the same time a process
for ongoing improvement.
There are six TOC Thinking processes:
1 The Current Reality Tree (CRT)
To answer; What is the problem?
2 The Evaporating Cloud (Cld)
To complete the answer to; What is the problem?, and To Find the direction of the solution.
3 The Future reality Tree (FRT)
To
answer the question To what to change to? To identify all the elements
of the full solution starting from the new direction identified and
agreed in process 2
4 The Negative Branch Reservation (NBR)
To
deal with the concerns raised by those seeing the suggested direction
and full solution. To identify the modifications needed to avoid new
negatives steming from the solution.
5 The Prerequisite Tree (PrT)
To
begin to answer the question: How to cause the proper people to cause
the change? By breaking the full solution down into smaller logical
sequenced steps
6 The Transition Tree (TrT)
To
complete the answer to the question: How to cause the proper people to
cause the change? By explaining where necessary the gradual change
envisaged that will occur to move from the starting point to one of the
steps in identified in process 5
