'clumsily-managed' originates from the combination of 'clumsy' and 'manage', where 'clumsy' meant 'awkward' and 'manage' meant 'to handle or control'.

'clumsy' changed from the Old Norse word 'klumsa', and 'manage' from the Italian 'maneggiare', eventually becoming the modern English words 'clumsy' and 'manage'.

Initially, 'clumsy' meant 'awkward in movement', and 'manage' meant 'to handle', but over time, 'clumsily-managed' evolved to describe something handled in an awkward manner.
