NetScout introduces a monthly series of editorials by well-known industry
analyst Jim Metzler.
IT organizations are increasingly involved in issues that may have broad
repercussions if not implemented properly. Mergers and acquisitions, data center
consolidations, and in particular business function outsourcing all affect an
enterprise’s ability to market its product and generate revenue, while new
corporate governance initiatives like Sarbanes Oxley may result in hefty fines
if not reported accurately.
