Transition Tree (TT)
In a previous posting
we presented the Prerequisite Tree (PRT).
The PRT is the first tool used to help us determine “How to cause the
change to happen.” In a global sense the PRT is used to help determine the
overall strategy of “How to cause the change to happen.” The strategy defines what Intermediate Objectives
(IO) are needed to accomplish the goal and in what order to accomplish
them. Once the IO’s are known and the
intrinsic order is established, then it’s time to implement. For most of the IO’s it might seem obvious
exactly what needs to be done to make them happen. For other IO’s the steps to accomplish them
might not be so obvious. For those IO’s without a clear path forward it will become
necessary to construct a tactical plan to accomplish the IO. Hence, the benefit and purpose of the
Transition Tree (TT) is to determine the tactical steps necessary to accomplish
the IO’s and, in turn, accomplish the overall strategy of the PRT.
Transition Tree (TT)
The
PRT structure is sufficiency based logic (If A…then, B). It is the thinking
process used to construct the tactical actions required to achieve a specific IO
and provides the detailed answer(s) to the question, ”How do I cause the change
to happen.” As the fifth and final
thinking tool the TT is often overlooked.
However, it should be noted that the TT is an excellent standalone tool
when used in isolation. For the sake of
this discussion we will be using the TT as a continuum for a full systems
thinking analysis as applied to a single IO from the PRT.
The
square cornered boxes represent Actions to be taken by you, or someone else. The round cornered boxes represent entities
that currently exist, or will exist, when the action(s) is/are taken and
completed. The end result of the TT is a
time sequenced plan of Actions and Desired Outcomes. The causality on the arrows implies
sufficiency – not time.
Building the TT
The
TT provides the detailed description of the Desired Outcomes (DO) that will
help us gradually evolve the changes we envision to occur in reality by
accomplishing the Defined Actions. It is
possible, in a full systems analysis, that the TT may be necessary for more
than a single IO in a PRT. If you read
an IO in the PRT and understand the necessary steps to accomplish the IO, then
a TT is probably not necessary. If you
don’t understand what to do, then a TT will provide some answers.
The
TT has four elements.
1. Objective –
The purpose of the TT. What is it you
want to accomplish? (For our discussion this will be an IO from the PRT)
2. Action –
An activity that leads towards the accomplishment of the objective.3. Desired Outcome – The planned target of the action. What you want an action to accomplish.
4. Need – The reason an action must be taken to achieve a Desired Outcome.
First Step-TT
For
this discussion, the first step to develop a TT is to define a particular IO
from the PRT which might seem especially difficult or troublesome to accomplish. By completing the PRT we know that the listed
IO’s must exist, as necessary conditions, to accomplish the PRT Objective,
i.e., “In order to have IO A … I must have IO B.” The IO’s in the PRT can only become part of
reality if they can be accomplished! If
a particular IO cannot be achieved, and it is a necessary condition (base of
the arrow) to achieve a different IO (tip of the arrow), then the IO at the tip
of the arrow cannot be accomplished if the necessary condition is absent.
Because
of its structure the TT is sometimes affectionately known as the “Backbone and
Ribs.” This nickname comes from the fact
that most of the Desired Outcomes (DO) are aligned in a column with the Actions
and Needs feeding the DO’s.
In
the case of the DOME Company PRT, there are several IO’s listed. Any one of them could cause some degree of
difficulty in trying to accomplish and some might even appear as projects within
themselves! Let’s pick one and go
through the step of building a TT. For
our discussion we will pick IO-11 to build a TT. State the objective – in this case IO-11.
If
we look at the objective and ask “What actions will be required to achieve the
objective” we can build a list of those actions.
2. Make a presentation to get management approval.
3. Have the staff available to create the training.
4. Conduct the training.
What
need are you trying to fill by taking action number 1? What would be the desired outcome from taking
this action?
