Order from company initially motivating chap and head of department (7)
I believe the answer is:
command
'order' is the definition.
(I know that order is a more specific form of the action organise)
'company initially motivating chap and head of department' is the wordplay.
'company' becomes 'co' (abbreviation).
'initially' says to take the initial letters.
'chap' becomes 'man' (chap can mean a man).
'and' means one lot of letters go next to another.
'head of' says to take the initial letters.
The first letter of 'motivating' is 'm'.
The first letter of 'department' is 'd'.
'co'+'m'+'man'+'d'='COMMAND'
'from' is the link.
(Other definitions for command that I've seen before include "Fiat" , "Bid" , "Direct" , "Understanding" , "Authoritative instruction" .)
