planning of a design

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
