Since outsourcing's popularity has been growing in recent years, it  comes as little surprise that bank spending on third-party computer   services increased 3.2% in 1996.   
What may surprise some, though, is that large banks - those with  more than $4 billion of assets - led the pack in outsourcing spending   growth.   
  
As recently as the early 1990s, many in this group shunned  outsourcing, considering it an abdication of control or a sign of weakness. 
However, the merger craze and the increasing pressure to diversify  delivery channels have combined to change many banks' minds. 
  
Outsourcing helps large banks absorb the operations of acquired  institutions in the short term and frees them to focus on developing   technology strategies for the longer term, experts said.   
The rise in big-bank outsourcing also has been fueled by vendor  response to lackluster demand for their services a few years ago. 
Instead of pushing for blockbuster contracts in which they manage  huge chunks of a bank's operations, many vendors now sell more tailored   services, enabling banks to farm out selected pieces of their computer   operations.
