The Problem Solving Spiral

Define The Problem Clearly

Think OfAlternativeSolutions

Choose TheBest Solution

Scientific Method & Design Process

Compared State the problem

Collect information

Form a Hypothesis

an explanation that can

be tested

Perform the

experiment

Analyzes the results

Repeat the process

with other samples

Reporting the findings

State the problem

Gather information

Create alternative

solutions

Select the best solution

Create a prototype

Evaluate or test the

prototype Communicate the

results of the test

Describe The Problem

Page 1 of 2

What is the problem or need? The first step is to Clearly Identify The Problem

Write the problem in one or two sentences.

Write it down helps to organize thoughts and understanding.

Read your sentences or say the problem out loud

The best way is to say it to others. Listeners help to check if it is

truly the problem or is more to the problem.

Stating the problem in Detail

Page 1 of 2

Also list all design constraints which are the

Specifications which are the guidelines or

regulationsAnd Limitations. which is the resources that

are available or not available.

Describe the problem, a List goals or what

needs to be accomplished.

6/13

Gather Background Information

Research saves valuable resources

(Labor, Materials, Energy, Capital ($) and Time)

Helps to design a better product or service

Extra time spent on this step most often saves

time etc. later. Examine current issues, and trends

Companies do market research to see if

customers want a product (Market Analysis, Product Surveys)

Explore other options via internet, library,

interviews, Etc.F


7/13

Develop Alternative Solutions Alternative Solutions are different possibilities

that may solve the same problem. Five ways of finding alternatives:

Past experience, Trial and error, Brainstorming,

Insight or by Accident

Brainstorming - each person makes suggestions

without evaluation during the brainstorm

meeting. Rule of Brainstorming: Listen to all ideas as it may lead toother ideas or solutions. No Put Downs!

Good brainstorming practice is to write every idea down

for later reference. G


8/13

Select The Best Solution First, compare the solutions & the stated problem to

see if the goals or intentions are met & it is within theresource limitations.

A tool that can help is to list advantages anddisadvantage of each alternative to aid in selecting thebest solution.

Other considerations

Impacts on society, environment and individualsshould be a consideration.

Values and morals - the way we feel aboutsomething

Tradeoffs - A compromise -we accept somerisks in order to obtain benefits

compromise

9/13

Create a Prototype

Implement or Actually building or

creating the solution

put the solution into effectto create the actual solution

A prototype is a working model

Simulation - a away of testing solution innear real conditions(astronaut & pilot training)

I


10/13

Evaluate The Solution Prototypes usually first build and used for

testing or evaluating a solution or plan to seeif it meets the needs to solve the problem.

A prototype is a working model

It is evaluated to see if it meets the design

constraints are specifications and limitations.

Technology often becomes obsolete. Companies that continue to evaluate often develop new

(up-grades) technologies and avoid having the company

become obsolete.

J


11/13

Communicate the solution(s)

Make an Engineering Presentation.Include how the solution best meets the

needs of the problem.

Discuss impacts to society, individuals,

and the environment.

An explanation of the trade-offs foreach solution and why this design is

the best solution.

K


12/13

Begin production

Redesign as needed

Redesign based on information gathered during

tests and presentations.

When design is finalized begin (mass) production.

Continue to monitor after production. Improve products based on consumer input.

Improve production methods to reduce costs,

improve safety for consumers and employees.

Best solutions work well, are economical and cause

the least harm to people and the environment.

L


13/13

Technology does have

positive and negative impacts!

Technology does have

positive and negative impacts!

Background to Problem Solving

For the best results follow the problem solvingprocedures, dont skip steps.

Keep a record of all ideas.

Remember good solutions often require trade-offs.

The best solutions work well, are economical, and

causes the least harm to people or the environment.

Depends on values,

who possesses the technology, and the trade-offs
