'methodically-planned' originates from the combination of 'methodical' and 'planned', where 'methodical' comes from the Greek word 'methodikos', meaning 'systematic', and 'planned' is derived from the Old English 'plann', meaning 'a flat surface or map'.

'methodical' changed from the Greek word 'methodikos' to the Latin 'methodicus', and eventually became the modern English word 'methodical'. 'Planned' evolved from the Old English 'plann' to the modern English 'plan'.

Initially, 'methodical' meant 'systematic', and 'planned' meant 'mapped out'. Over time, 'methodically-planned' evolved to mean 'carefully organized and executed according to a systematic plan'.
