When to use problem solving methods
Problem solving methods can be used for:
•
developing a solution definition based on the
business requirements.
•
resolving issues.
•
treating risks.
•
general problem solving.
3
The problem solving process
Three simple steps:
1. Clarify the problem.
2. Identify a number of possible solutions.
3. Assess possible solutions to determine the most
suitable.
4
Step 1 - Clarify the problem
•
Write down a statement of the problem.
•
Is the stated problem clear and precise? If not refine
the statement.
•
Is this merely a symptom of an underlying problem?
•
Can this problem be split into separate smaller
problems?
•
Are there better ways of stating the problem?
•
What assumptions are inherent in the problem?
5
Step 2 - Identify solutions
•
Use a technique such as brainstorming to generate
possible solutions.
•
Identify as many potential solutions as possible.
•
Do not filter out potential solutions, keep an open
mind until you see how they will work.
•
Once you have generated lots of ideas, consider
each one to see how it could be refined to solve the
problem.
6
Step 3 - Assess solutions
•
Shortlist your potential solutions to those that are feasible.
•
Assess what the value of the problem is? What would it be worth to fix
or what would it cost if it was not fixed?
•
Determine the criteria to be used to assess the solution. Factors to
consider are: the requirements, short term vs. long term solutions, costs
of the solution relative to the cost of the problem, etc.
•
If some cirteria are more important than others apply weightings to the
criteria accordingly.
•
Determine the impact of the solutions being considered on other areas
of the business. Consider the bigger picture. Is a similar problem being
addressed elsewhere?
•
Assess the level of risk in the proposed solutions. Is fixing this problem
likely to cause other problems?
•
Assess how well each solution meets the criteria and based
on the weighting determine an overall score for each solution
to select the best fit..

Use MECE*
MECE stands for Mutually Exclusive and Collectively
Exhaustive.
The MECE approach can be applied both in clarifying the
problem by listing the issues, and in developing a list of
alternative solutions.
When producing a list make sure:
•
each item is a separate and distinct item
– it is Mutually Exclusive.
•
All items have been identified
– it is Collectively Exhaustive.

8
Use SIP
SIP stands for Situation Implication Proposal.
The SIP approach is another way of working through a
problem.
With SIP ask:
•
What is the Situation we are dealing with?
- describe this in detail.
•
What are the Implications of the situation what effect is this having?
•
What is Proposed to address this?

Helpful hints
Don’t:
Do:
– Make assumptions
– Clearly state the problem
– Jump to conclusions
– Identify several solutions
– Promote one solution
without evaluation
– Assess potential solutions
based on real or agreed
requirements
– Allow only the technical
people to propose
solutions
– Ensure that business users
accept the proposed
solution
– Attempt to solve the
problem in isolation
– Consider the big picture
and the context

When you get stuck
The “cleaner” technique for solving problems.
It’s late at night and Mike has been trying to work out why his computer program is not
working and he is really stuck.
Into the office wanders the cleaner, with his vacuum pack on his back and starts
dusting.
Mike calls him over. “Hey Joe, help me with this computer problem I am having.”
Joe replies “I don’t know anything about computers!”
“That’s fine, just listen” says Mike.
As Mike explains the problem to the cleaner he suddenly realises what is causing the
problem…
“Thanks for your help Joe” says Mike.
“ It’s nothing.” says Joe honestly.
So, what happened?
Just by explaining the problem to someone else the answer can reveal itself!
If all else fails, sleep on it.
