WHR is a registered charity, and is run according to its constitution. This defines such thing as our purpose, how our executive committee is made up and elected, and what we may and may not do.
A hospital radio station such as WHR is not a static organisation. For example, our audience might change its requirements, or we might wish to expand the type of programmes we provide.
This also might require that new equipment is build or purchased...which requires both time, planning and money.
WHR therefore has a rolling 5 Year Plan, which details what WHR wishes to do in that period.
