Based on an assessment of the major environmental factors that affected GM at the time of the case, which do you believe are most significant in each area? Economic (include labor cost, pension, and healthcare issues)? Legal (include CAFE)? Technological (include product quality/technology)? Social (include GM's market perception/brand equity)? Overall, what environmental factors are the most significant? Could GM's management have addressed these issues in the past before they became critical? Or did they contribute to making these matters worse?
