Describe the limitations of systems theories
What will be an ideal response?
While systems models often provide useful concepts for describing person-situation interactions, they may have limitations in suggesting specific intervention prescriptions (Whittaker & Tracy, 1989). Similarly, Wakefield (1996a, 1996b) has argued that systems concepts do not add much to domain-specific knowledge. Others claim that, however faulty or inadequate, systems theory provides useful metaphors for conceptualizing the relations between complex organizations. Perhaps we should not place such high expectations on the theory (Gitterman, 1996). We take the view that systems theory provides useful metaphors for conceptualizing the varied levels of phenomena social workers must recognize. By themselves, those metaphors are insufficient to guide practice. Concepts such as equifinality and multifinality cannot be rigidly applied in all human and social systems.

Jack Jackson, owner of the Jackson Automobile Supermarket, wanted to find out the kinds of cars to push to graduating college students
He asked 100 college seniors to rate ten aspects of 11 models his dealership sold: style, fuel economy, engineering, safety, performance, prestige, comfort, price, selection or options, and interior size. Each car was rated on the ten aspects from 0 (poor) to 5 (excellent). Each student also rated the importance of each aspect (1 = unimportant, 2 = moderate importance, 3 = very important). Then each aspect rating was weighed (multiplied) by its importance rating. Next, everything was added together for a score. Each car received a score of 0 to 150. After calculating the information and reviewing the results, Jack focused on selling cars with scores of 80 and higher to graduating students. What measurement technique did Jack use in his study? A) semantic differential B) Bogardus Social Distance Scale C) Likert scale D) Hawthorne scale E) an index
