Different client populations, variations in instruction techniques and knowledge of response generalization all point to that conclusion that traditional behavior analysts might be largely at a disadvantage in the area covered by OBM: that of a management and team leading and training typically developing clients. Behavior analysts require a background in OBM, otherwise they might "reinvent the OBM wheel" or - which is worse - apply their experiences one-to-one with special populations and bring with them harmful assumptions.
