What is supervision?
The word supervision is  used a wide variety of senses. Most doctors and dentists use the term  only in the context of formal training (eg in educational and clinical  supervision for juniors). However, in other professions the term is used  for a wider variety of conversations including case discussions between  established clinicians. For example, in nursing it is understood as:
‘An exchange between practising professionals to enable the development of professional skills.’(Butterworth)
In  our courses, we use the word supervision in this wider sense, to mean  any focussed conversation between professionals about their work. The  implication is that supervision is something that should happen  throughout professional life, from student days to lifelong learning. 
It  is helpful to think of supervision in terms of two circles –  development and performance. Sometimes supervision can be purely  developmental and sometimes purely oriented towards performance. However  in most supervision both are involved. Much depends on context ie who  is asking for what to be done, who is reporting to whom and why.  Although it is conventional to make a distinction between supervision,  mentoring, coaching and career guidance but it practice many  conversations will range between these. 
 
What does supervision address?
Cases: 
Most  supervision takes place in order to address cases. These may be  addressed in terms of technical management but often they raise broader  issues, for example:
• when there is no one easy answer
• ethical issues
• complex cases
• ‘grey area’ cases: eg somatisation, frequent attenders, chronic fatigue, irritable bowel 
•  complaints, distressed families, angry patients, unlikeable patients
Contexts. 
Cases  never occur in a vacuum. Case management often depends on trying to  achieve coherence among the professionals. Supervision may need to  address:
• professional or interprofessional rivalries
• problems concerning communication
• teamwork issues
• roles and boundaries
• the differing expectations of patients and clinicians
• money, politics, gender, sexuality and power
Careers. 
Case conversations quite often bring up issues about careers, for example:
• the need for further training
• work place conditions and job prospects
• longer term career aspirations
A narrative approach to supervision skills
There  is evidence that skilled supervision sustains morale, increases job  satisfaction, lessens stress, prevents burnout and dropout, and reduces  complaints and litigation. Supervision skills are similar to good  consultation skills and to effective team communication. All of these  share the same micro-skills (hypothesising, open questions, empowerment)  and model a reflective attitude (respect, thoughtfulness, seriousness,  complexity).
People doing supervision use all sorts of  approaches: informal chat, eclectic methods, approaches based on  educational theory or counselling, psychodynamic ones etc. The approach  taught in the London Deanery is a ‘narrative’ one: we have found that  this approach makes sense to many clinicians and is easier to learn and  teach than some other approaches. 
A narrative approach to  supervision does not reject other frameworks such as evidence based  medicine, clinical science, psychodynamic understanding etc. What it  offers instead is an overarching framework that allows people to value  these as helpful contributions that can generate useful ways of looking  at the world that may or not make a difference to someone’s story. It  encourages us to see different discourses as sources of helpful  hypotheses rather than absolute truths, and lets us move flexibly  between these. A narrative approach encourages the exploration of  ‘polyphony’ ie valuing the different stories that anyone is capable of  telling about the same experience. Hence, agreed ‘truths’ are  established by the process of dialogue itself.
There is a close  connection between narrative ideas and systemic ones: ie the idea that  we continually create our realities in conversation with people around  us, and that families, societies and cultures are defined through their  shared stories. In other words, our understanding of the world is always  ‘dialogical’ in its origins and can be developed further through  dialogue. We have spent the last decade at the Tavistock Clinic and  London Deanery (now Health Education England) trying to make use of  narrative and systemic ideas and skills for everyday consultations and  supervision. We see our approach as one that completes the triangle  between narrative studies, narrative approaches to therapy, and  medicine.
Helen Halpern has formulated these in terms of the following ‘rules’ in relation to narrative-based supervision.
 
• The  supervisor is not considered to be in a position of authority over the  supervisee unless circumstances absolutely require this (eg concerns  about performance). The supervisor’s role is to help the supervisee  reflect and expand the narrative they present in a non-judgemental way.
• It  is not necessarily expected that the conversation will lead directly to  any solution but may simply help shift the dilemma or narrative in a  more helpful way for the supervisee.
• The supervisor should not offer advice unless specifically requested by the supervisee.
• The  conversation does not at first set out to explore the supervisee’s  feelings, although their emotional response may become an important  factor to consider.
• The supervisor asks questions rather than offering interpretations.
• Each question that is asked should be based on the response to the previous question.
• In general the supervisor should not ask a question if they think that both they and the supervisee already know the answer.
• The supervisor needs to pay close attention to the language used by the supervisee and to track this and its meaning.
• The supervisor notes non-verbal cues and body language and uses this to help frame subsequent questions.
• The  supervisor will necessarily base their questions on their own knowledge  and experience but needs to be wary of making assumptions and imposing  these on the supervisee. Indeed one of their roles may be to challenge  the supervisee’s assumptions.
