                        PUGH CHART
                  TEAM Number 1 
     Task 1- Assign weights to the objectives
objectives Weights
Safety 10
Ease of use 9
Portability 8
Use of stand parts 4
cost 7

Task 2 - Write Pugh Chart for the 4 alternative designs shown in the figure

Design Objectives Weights Concept 1 Concept 2 Concept 3 Concept 4 Concept 5
Safety 10 -' +' datum ++' +'
Ease of use 9 0 0 datum ++' +'
Portability 8 -' 0 datum 0 0
Use of standard parts 4 0' +' datum ++' +'
Cost 7 -' -' datum -' 0'
Score (+) 38 0 14 datum 42 23
Score (-) 0 -25 -7 datum -7 0
Total 38 -25 7 datum 39 23 
         Task 3 : Justification for the scores given
Design No. Objective Scores Allocated Justification for the score
1 Safety -10 might not be much safe to use
Ease of use 0 requires more energy to use
Portability -8 not easy to carry and might be heavy
Use of standard parts 0 The parts used in making the machine can't be found easily
Cost -7 apparatus might be expensive
2 Safety 10 safe to use
Ease of use 0 requires more energy to use
Portability 0 not easy to carry
Use of standard parts 4 parts might be found easily
Cost -7 apparatus might be expensive
3 Safety - datum
Ease of use - datum
Portability - datum
Use of standard parts - datum
Cost - datum
4 Safety 10 is more safe to use
Ease of use 09 requires less energy to use
Portability 0 easy to carry
Use of standard parts 04 The parts used in making the machine can be found easily
cost 0 apparatus might be expensive
