Suppose that we wish to use several methods to obtain data from several sources for a
program evaluation. Because not all data are equally valuable and because the costs of
collection vary from method to method, the question arises as to whether it is possible to
maximize information yield for a fixed, limited budget. How this problem was structured
and solved for a particular program evaluation is described in this article. The approach,
which uses a mathematical technique known as linear programming, is easily generalized
to other program evaluations.
