Now
that you’ve been through a full systems thinking analysis, you can see, at
times, how involved and difficult it can be for many people. In fact, many people
who have gone through the full TOC Jonah training sessions have come away
feeling a bit overwhelmed and sometimes feeling like they simply don’t know
where or how to begin. And even if they do know where to begin, they
sometimes are overcome by feelings of uneasiness on their ability to complete a
full TP analysis. Add to this how
difficult it is sometimes to convince your company’s leadership to block out
several days to perform such an analysis and you probably feel like not even recommending
it.
What
if there was a way to arrive at some or most of the same conclusions as the
full TP analysis without actually going through a full analysis? What if there was another logic diagram that was
easy to learn and construct and one that wouldn’t fill you with anxiety and
uneasiness? Guess what friends, there is such a tool that is both easy to
learn and requires only a fraction of the time it takes to do a full TP
analysis!! Over the next few series of
postings Bruce and I are going to walk you through how to construct and use this
tool. We’ve written about it in many
other postings, but this time we’ll use it in a case study setting to add
relevance to it. The tool I’m referring
to is the Intermediate Objectives Map (IO Map) and as we said, even though it
has been the subject of other postings, we want to present it in a slightly
different light. But before we do, let’s
review the basics of the IO Map.
If
you’re like us, you might have gone through a full Jonah course and learned (or
at least studied) all of the TOC Thinking Process tools. Not all Jonah training sessions include the
IO Map, but it was included for us. The
IO Map stood out for us because of its simplicity and ease of use. Since
then we have used the IO Map in a wide assortment of industries and in every
single instance the leadership team not only understood it, they emphatically
embraced it. The real strength of the IO Map is that on a single document
you will have listed everything that must be in place to achieve the goal of
the organization. No other tool does so
with such ease and in such a short time frame.
Bill
Dettmer, who has written extensively about the IO Map, explained to us that his
first exposure to the IO Map dated back to 1995 during a management skills workshop
conducted by Oded Cohen from the Goldratt Institute. In more recent
years, Dettmer has recommended that the IO Map, which he now calls a Goal Tree, should be included as the
first step in a Thinking Process analysis. He explains that this is
because the Goal tree defines the standard for goal attainment and its
prerequisites in a much more efficient and well-organized manner. We
believe that the IO Map is perhaps the best focusing tool to better demonstrate
why an organization is having problems achieving its goal. Other
advantages of using an IO Map include a better integration of the rest of the
TP tools that will accelerate the completion of Current Reality Trees, Conflict
Clouds and Future Reality Trees. Although both Bruce and I believe that
Bill Dettmer is absolutely correct in recommending the IO Map be used in
conjunction with the other TP tools, the other thing we like about IO Maps is
that they can be used as a stand-alone tool.
We believe that using it in this manner will result in a much faster
analysis of the organization’s weak points or areas that an organization should
focus their improvement efforts. In the next few postings we will discuss
the IO Map as a stand-alone tool.
When
we use the logic based TOC Thinking Process tools there are two distinctly
different types of logic at play, sufficiency
and necessity type logic.
Sufficiency type logic is quite simply a series of if-then statements. If I have “x”, then I have “y”. On the other
hand, necessity-based logic trees use the syntax, “in order to have “x”……I
must have “y.” The IO Map falls into the necessity-based category.
For example, in order to have a fire, I must have a fuel source, a spark and
air which are called Critical
Success Factors (CSF’s). If the
goal is to have a fire, you must have all three components in place. If
you remove one of the CSF’s, you simply will not have a fire.
The
hierarchical structure of the IO Map consists of a single Goal, several Critical
Success Factors (CSF’s) which must be in place to achieve the goal and a
series of Necessary Conditions (NC’s)
which must be in place to achieve each CSF. The Goal and CSFs are written as
terminal outcomes as though they were already in place while the NC’s are
written more as activities which result in each of the CSF’s. In our next posting we will use a fictitious setting to construct an IO Map and then begin discussing how we can use it to develop an improvement plan.
