In this provocative article, the author sets out a personal list of ''
problems' that must be solved if the field of system dynamics is ''...
to advance beyond a craft, to approach the rigors of a science''. The
problems include issues in the enhancement of technical and interpret
ive aspects of modeling, and in the advancement and propogation of goo
d practice. These identified problems are characterised as those that
are through their difficulty, deserving of continuing attention, and a
t the same time are those that threaten the field if not resolved. The
article carefully ends with an epilogue inviting response, rather tha
n a conclusion.
