Good supervision relies on open communication between the supervisors and the candidate. At the outset of the project, it is important that all parties are clear about their expectations of each other. These expectations will be discussed as part of the "Student-Supervisor Agreement", which should occur early on in candidature and a copy of the agreement must be uploaded in eVision as part of the first progress report process.
It should be accepted by all concerned that the early phases of work may lead to problems which will need to be worked through in a constructive manner if the project is to flourish. Although academic matters will be of primary concern, students and supervisors should be prepared to talk candidly about other issues affecting the candidate's ability to make progress with the PhD.
Be sure to revisit the student-supervisor agreement from time to time. It is important that the agreement is not forgotten, and that you and your supervisor stay on track with following it. The agreement can be customised later on, but try not to make any extensive changes.
