'unreliably-managed' is a compound word formed from 'unreliable' and 'managed'. 'Unreliable' originates from the prefix 'un-' meaning 'not' and 'reliable', which comes from the Latin 'reliabilis', meaning 'that may be relied on'. 'Managed' comes from the Latin 'manus', meaning 'hand', and 'agere', meaning 'to act'.

'Unreliable' evolved from the Middle English 'rely', which was influenced by the Old French 'relier', meaning 'to bind'. 'Managed' evolved from the Italian 'maneggiare', meaning 'to handle'.

Initially, 'unreliable' meant 'not able to be trusted', and 'managed' meant 'handled or controlled'. The compound 'unreliably-managed' retains these meanings, indicating poor management.
