Problem Solving Processes
In technology, there are many different types of problems
that need to be solved. Therefore there are many types of
problem solving processes. These processes include:
Troubleshooting
Research and development
Invention and innovation
Experimentation
Design
Design
Design is the most important problem
solving process in the development of
technological products.
.
Design
Design is a creative planning process that leads to useful
products and systems.
Design
There is no perfect design.
Design
Requirements for a design are made up of
criteria and constraints.
Design
Design involves a set of steps, which can be performed
in different sequences and repeated as needed.
Identify the problem,
Define or refine the problem,
Gather information,
Develop alternate solutions,
Select and refine the best solution,
Express the design solution,
Build a model or prototype of the solution,
Evaluate, revise and refine the solution,
Communicate the solution.
Design
Brainstorming is a group problem-solving design
process in which each person in the group presents his
or her ideas in an open forum.
Design
Modeling, testing, evaluating, and
modifying are used to transform ideas into
practical solutions.
Design Brief
A written plan that identifies a problem to
be solved, its criteria, and its constraints.
The design brief is used to encourage
thinking of all aspects of a problem before
attempting a solution.

Design Brief
The design brief helps to create a real problem solving situation. A design
brief should not contain any vague information but enough information to
solve the design challenge.
Design Brief
A design brief must contain the following:
Topic or Title
Description of the situation. This puts the students in a real life situation.
Description of the need or the problem to be solved. This is sometimes
stated as a challenge.
The objectives of the design challenge. Usually taken from the standards
and benchmarks.
Criteria and constraints. These list the requirements and limits that the
solution must meet.
Resources that are available.
Guidelines for evaluating and testing the solution.
A description of how the students will be assessed.
An opportunity to reflect or summarize what was learned and
accomplished.
