Very few solution
requirements are
represented in the design
indicating limited
interpretation of the
analysis.
Some solution
requirements are

key aspects of the
analysis
Key solution
requirements are
represented in the design
indicating a sound
interpretation of the
analysis
Most key solution
requirements are
represented in the design

All key solution
requirements are
represented in the design
indicating a thorough

Very limited or
inappropriate design tools
are selected and limited
techniques applied to
outline the data types,
structures and how the
solution will function. A
range of errors of fact or
logic affect the quality of
the designs.
Few appropriate design
tools are selected. Some
correct techniques are
used to describe data
types, structures and how
the solution will function.
Some errors of fact or
logic affect the quality of
the designs.
Some appropriate design
tools are selected. Mainly
correct techniques are
applied to describe data
types, structures and how
the solution will function.
Some errors affect the
quality of the designs.
Appropriate design tools
are selected. Correct
techniques are applied to
describe the data types,
structures and how the
solution will function.
Minor errors exist.
All selected design tools
are appropriate. Correct
techniques are precisely
applied to accurately
describe data types and
structures and how the
solution will function. The
designs are error free.
Limited checking of the
reasonableness of data.
Limited validation
techniques used to check
the reasonableness of
data.
Some validation
techniques adequately
check the
reasonableness of data.
Most validation
techniques efficiently and
effectively check the
reasonableness of data.
All validation techniques

Limited tests partially

does not operate fully as
intended.
Some tests detect why
key requirements of the
solution do not operate
as intended.
Testing confirms that
most requirements of the
solution operate as
intended.
Systematic testing
confirms that the key
requirements of the
solution operate as
intended.
Comprehensive testing
confirms that all
requirements of the
solution operate as
intended.
