By The McKinsey Quarterly - In this slowing global economy, smart companies are proactively weeding out underperformers, but staying away from sweeping layoffs that starve good business and destroy morale. Best practices involve shying away from quick solutions to cut costs.This means fostering thriving R&D projects instead of trimming direct research expenses.

Infuse your corporate culture with the sense of urgency the present economy demands and even consider searching outside areas for specialized talent.
