Demand for IT services is driven by rapid technological advances, but spending depends on the health of the economy. The profitability of companies depends on technical expertise, innovative services, and effective marketing. Large companies have advantages in broad service offerings and global reach, which give them the ability to provide outsourcing services to big corporate customers. Small companies can compete effectively by specializing in market niches or by partnering with larger companies that want to broaden their mix of services. The US industry is fragmented: the 50 largest companies account for about 40% of revenue.
