Turnaround strategy aims to transform a loss-making company into a profitable one by reversing declining sales, weakness, and instability. It addresses problems like declining market share, negative profits, high costs, and poor management. Effective turnaround involves consulting external specialists, removing unhelpful management, and merging with stronger organizations. Approaches can be surgical, targeting specific issues, or non-surgical, targeting the overall business model. Lou Gerstner's successful turnaround of IBM involved cost reduction, remaking the brand, organizational changes, and changing management practices. This reversed IBM's fortunes and led to improved rankings and brand valuation.
