Abstract: A computer implemented method for controlling instances of a process comprising: receiving feedback data on instances of the process, wherein the feedback data comprises a plurality of response values relating to aspects of each process; calculating standard response values for the process based on the feedback data; identifying outliers in the response values for the process in the feedback data from the calculated standard response values; and generating at least one workflow to control and regulate the process based on the identified outliers.

Abstract: The present invention relates to a computer implemented method, the method comprising: receiving, on a local computing device (130), configuration data identifying a transaction or service provided to a user; wherein the configuration data is arranged to enable a user device (120) to access a payment request in respect of the transaction or service and an identifier dependent on the transaction data; wherein the identifier comprises server access information adapted to enable the user device to access a server (140) with the identifier thereby enabling an association or link to be made at the server (140) between the user device (120) and review data in respect of the transaction or service.
