A before-versus-after program comparison design can show changes in relevant conditions before and after the program's implementation, but it cannot definitively attribute those changes solely to the program's operation. Other factors could potentially be influencing the changes observed. Controlled experimentation and time-trend projections can provide more concrete evidence of program impact.
