The sequence of work activities that occur while performing tasks such as loan application processing or new account opening is captured by bank operations data flow. Banks use these flow charts to improve employees' productivity, customer service, and profitability. Banks can also use bank operations data flow to identify automation opportunities and capture the information needed to automate specific tasks. Internal teams in mid-size and large banks typically analyze business processes to improve productivity and customer service. Certain large commercial banks have entire centers of excellence dedicated to processing automation and cost reduction. Bank operations data flow, regardless of size or region, can be used to the bank's advantage in various ways.
