Abacus work
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
