Subject: Learning by Doing
Learning by doing (originally described by Kenneth Arrow in his 1962
paper, 'The Economic Implications of Learning by Doing') describes how the
unit cost of production is a function of total cumulative output. As
individuals gain experience in undertaking some repetetive task, their
efficency in performing this task increases and the time taken to
complete the task decreases.
'The learning curve', is usually referred to in percentage terms, in
terms of the reduction in percentage cost per doubling in cumulative
output. A '90% curve' means that costs decrease by 10% with a
doubling in accumulated experience.
You can experiment with it yourself e.g. by building a Lego caste several
times and plotting the time it takes each time you construct it.
How would you think about this phenomenon in HPCT terms? Would you get any
additional insights by thinking about it in HPCT terms, e.g. in terms of
reorganization? How would you model it?
