The invention relates to a computer implemented method of managing tasks, such as maintenance tasks, within a process plant. The invention detects the presence of a suitable qualified user near a part of the plant needing work and provides to that user on a portable user interface process diagrams detailing the work to be performed. The invention can automatically verify that the work on the plant has been completed. Permission tokens are used to control the access of the user to the plant. The Hearing Officer applying the Aerotel Test found that the contribution provided by the claimed invention, notably the way in which it interacted with the process plant did provide the necessary technical contribution. The application was therefore found not to be excluded as either a program for a computer or a method of doing business. The case was remitted back to the examiner to complete their examination.
