A) Your firm uses off-the-shelf software (HEAT Help Desk) to manage customer support service calls and to maintain customer site configuration information; however, your firm failed to adequately validate this software in order to ensure that it will perform as intended in its chosen application. Specifically your firm's validation did not ensure that the details screen was functioning properly as intended. The details screen is used to capture complaint details and complaint follow-up information which would include corrective and preventative actions performed by your firm when service calls are determined to be CAPA issues.
