Management (at least as reflected by popular management culture) is no
w more interested in redesigning systems completely than in marginal o
r continuing improvements. Some practical MS/OR work has recognized th
is and produced new systems that have changed their sponsoring organiz
ations and provided them with competitive advantages. This paper consi
ders the importance for MS/OR workers of focusing on system design rat
her than analysis aimed at supporting improvements in existing systems
. It notes that MS/OR has traditionally perceived itself predominantly
as analysis in this latter sense, and discusses the difference betwee
n design and this form of analysis. It then uses some Edelman prize fi
nalist papers to illustrate the cycle of design-oriented MS/OR project
s. Finally, this paper considers the opportunities and challenging pro
blems afforded by system design, with particular reference to techniqu
es, education, and the future success of MS/OR.
