Samsung managers have studied past product recalls, including those at Toyota Motor Corp., and the conclusion seemed clear: Move quickly and dramatically. But Samsung moved so fast it got ahead of regulators who help organize such programs. In the U.S. for example, companies are supposed to notify the Consumer Product Safety Commission within 24 hours of uncovering problems. Instead, Samsung went public on its own and consumers didn't have clear guidance on how to exchange their phones. "The official recall process provides a lot of clarity to consumers and there's someone checking to make sure the fix is a good one that serves the consumers in terms of safety," said Jerry Beilinson, a technology editor at Consumer Reports. While Samsung says Galaxy Note 7 sales will resume in Korea around Sept. 28 it has yet to specify when global sales would resume. The tumult has raised questions about whether Samsung's current management approach is sufficiently robust to handle the crisis fallout.
