Computer systems and software applications help insurance companies streamline operations and manage business more efficiently. Some key ways computers are used include: 1) Maintaining customer records and policy information in databases. 2) Performing complex calculations like risk assessments faster. 3) Generating documents like pay slips and statements more quickly. However, implementing computer systems presented some challenges for insurance companies like employees resisting change, high costs, and lack of technical skills. Steps taken to address issues included training programs, hiring expert staff, developing suitable software, and making employees aware of computer benefits.
