This article is based on the ten-year experience of an operations rese
arch project in Bangladesh. It assesses how, and under what circumstan
ces, research-based advice and results of pilot projects contribute to
change in large-scale public programs. It discusses project research
on issues facing the national family planning program: recruitment and
training of field-workers; delivery of injectable contraceptives; man
agement information; field-workers' use of service registers; field su
pervision; satellite clinics; and contraceptive user fees. These issue
s are used to illustrate the advantages and disadvantages of a long-te
rm institutionalized project, and to describe the diversity of means f
or communication with policymakers. The analysis shows that research,
policy decision, and implementation can occur in any sequence. Policy
advice that disrupts long-standing power relationships and organizatio
nal culture takes a great deal of effort to implement. Operations rese
arch can produce useful changes in organizational behavior, even when
large-scale problems remain.
