A computer-implemented method for managing access to an asset based on workorder-dependent access rights, the method being performed by an access management server, comprising: defining an association between a workorder and an access right, wherein the workorder is to be performed at an asset, and wherein the access right grants access to the asset; allocating the workorder and the associated access right to a first operator person being assigned to perform the workorder; sending the associated access right to a first operator device of the first operator person; receiving a re-allocation request from first operator device requesting to re-allocate the workorder to a second operator person having a second operator device to be assigned to perform the workorder instead of the first operator person; performing re-allocation and sending the associated access right to a second operator device of the second operator person.
