Make sure team members are given access cards, login passwords etc as soon as they start on the job.
An induction should be done as soon as possible, including giving access cards to the building.
It may seem to save some money by only doing the induction and card granting process once a month, but the difficulties associated for the employee to wait for someone else to open doors etc means less time they spend on the project.
Temporary cards are not good enough if they don’t give all the access the person should get. (Many temporary access cards don’t work or set off the alarm outside office hours, if the person needs to start early or work late, they cannot).
