A
qualitative method of analysis
used
to identify areas for improvement, used individually or as a
group
Used to rate a product on social, economic and environmental areas, in both the
analysis and planning of a design
 The
activity
•
Each individual or group needs a few blank abacus
sheets
• Identify a number of issues affecting social, economic or environmental
factors and decide which issues you would like to address
• Write each issue down, listing the
ideal condition at the top and the worst condition at the bottom
e.g.
for
'end of life' the ideal condition is easy to
disassemble & the worst case is difficult to
disassemble
• Estimate how good or bad the current product
is in each
area, and how confident you are about
your estimate
• Once all the issues have been considered draw a line to
connect
all the points in the issues area and all the points in the confidence levels
The Abacus is useful when:
•
Comparing
two products or designs, using
different coloured pens
• Assessing confidence
levels
