3.5
problem solving process
·
There are many approaches
to problem solving, depending on the nature of the problem and the people
involved in the problem. The more traditional, rational approach is typically
used and involves, e.g., clarifying description of the problem, gathering
information ,identifying alternatives,
assessing each alternative, choosing one, implementing it, and
evaluating whether the problem was solved or not.
·
All that worrying can become directed
thinking by channeling it into the following procedure. To make the best
decisions and to become valuable knowledge workers, we can follow this simple
five-step plan.
3.5.1
Identify
and clarify the problem. Our
first task is recognizing that a problem exists. The first step in reaching a solution is pinpointing
the problem area. Look at the situation carefully. Figure out what it is that
you are trying to solve. This will be your problem.
The normal process for solving a problem will
initially involve defining the problem we want to solve. we need to decide what
we want achieve and write it down. Often people keep the problem in their head
as a vague idea and can so often get lost in what they are trying to solve that
no solution seems to fit. Merely writing down the problem forces you to think
about what you are actually trying to solve and how much you want to achieve.
The first part of the process not only involves writing down the problem to
solve, but also checking that we are answering the right problem. It is a
check-step to ensure that we do not answer a side issue or only solve the part
of the problem that is most easy to solve. People often use the most immediate
solution to the first problem definition that we find without spending time
checking the problem is the right one to answer
3.5.2
Problem
analysis (Information Gathering) Learn more about the problem situation.
Look for possible causes and solutions. This step may mean checking files,
calling suppliers, or brainstorming with fellow workers. For example, the
air-freight delivery service would investigate the tracking systems of the
commercial airlines carrying its packages to determine what went wrong. The
next step in the process is often to check where we are, what the current
situation is and what is involved in making it a problem. For example, what are
the benefits of the current product/service/process? And why did we decide to
make it like that? Understanding where the problem is coming from, how it fits
in with current developments and what the current environment is, is crucial
when working out whether a solution will actually work or not. Similarly
we must have a set of criteria by which
to evaluate any new solutions or you will not know whether the idea is workable
or not. This section of the problem solving process ensures that time is spent
in stepping back and assessing the current situation and what actually needs to
be changed.
After this investigation, it is
often good to go back one step to reconfirm that our r problem definition is
still valid. Frequently after the investigation people discover that the
problem they really want to answer is very different from their original
interpretation of it.
3.5.3 Generating possible Solutions When we have
discovered the real problem that we want to solve and have investigated the
climate into which the solution must fit, the next stage is to generate a
number of possible solutions. At this stage we should concentrate on generating
many solutions and should not evaluate them at all. Very often an idea, which
would have been discarded immediately, when evaluated properly, can be
developed into a superb solution. At this stage, we should not pre-judge any
potential solutions but should treat each idea as a new idea in its own right
and worthy of
3.5.4
Analyzing
the Solutions This
section of the problem solving process is where we investigate the various
factors about each of the potential solutions. We note down the good and bad
points and other things, which are relevant to each solution. Even at this
stage we are not evaluating the solution because if we do so then we could
decide not to write down the valid good points about it because overall we
think it will not work. However we might discover that by writing down its
advantages that it has a totally unique advantage. Only by discovering this
might we choose to put the effort in to develop the idea so that it will work.
3.5.5
Selecting
the best Solution(s)
this is the section where we look through the various influencing factors for
each possible solution and decide which solutions to keep and which to disregard.
we look at the solution as a whole and use our
judgment as to whether to use the solution or not. In Innovation
Toolbox, we can vote using either a Yes/No/Interesting process or on a sliding
scale depending on how good the idea is. Sometimes pure facts and figures
dictate which ideas will work and which will not. In other situations, it will
be purely feelings and intuition that decides. Remember that intuition is
really a lifetimes experience and judgment compressed into a single decision
Draw conclusions from the gathered evidence and pose solutions. Then, weigh the
advantages and disadvantages of each alternative. What are the costs, benefits,
and consequences? What are the obstacles, and how can they be handled? Most
important, what solution best serves our goals and those of our organization?
Here's where our creativity is especially important.

want to try the
Product advertised why
?why not ?
3.7.8
Story Writing
Explain the students that we are
going to begin a story and that each student will discuss how the story could
end. Start with something like: "Once upon a time, there was a
…………….story should not be more than one page.
3.7.9
The chillies Experiment
Naeem and his 12-year old brother waqas bought
hot chilly pepper seeds, and planted some under a tree in their backyard. When
the chillies were ready to be eaten, Naeem was disappointed because they were
not hot. Why were the chillies not hot? Waqas’s hypothesis was that the plants
were not watered enough. Naeem disagreed. His hypothesis was that the plants
didn't get enough sun. They decided to conduct an experiment to find out who
was right.
