The difference is in how the client is the centre in decision making. Other approaches are often based on "Professionals specialist knowledge and views", decisions are made by the professionals in meetings that clients may not even be part of. Their view might be sort but not fully considered.
Person centred planning involves the client at every stage. It seeks to help the client set their own goals and make decisions about how they will try to achieve them. It aims to give the client back control in their lives and encourages them to develop problem solving skills and to consider their own best interests.
Obviously it raises dilemma's when clients are unable to consider what "professionals think" is their best interests.
I don't know what area you work in but person centred planning with the disabled, LD and in Social work are probably good area's to do an internet search as PCP is big in these areas right now. You can then consider how the information is transferable to your workplace.
Hope this helps a bit
