Silver Dane worked according to schedule (6)
I believe the answer is:
agenda
'schedule' is the definition.
(synonyms)
'silver dane worked' is the wordplay.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'worked' indicates anagramming the letters.
'dane' with letters rearranged gives 'enda'.
'ag'+'enda'='AGENDA'
'according to' acts as a link.
(Other definitions for agenda that I've seen before include "things still to be done" , "Schedule of items for meeting" , "List of items for committee to consider" , "List of items of business for committee" , "Schedule, order of business" .)
