Ka tohuhia te piri tika ina tāpirihia he rīpene rīpene ki tētahi rauemi, ā, ka piri tonu te kiriata ki te papa i muri i te tangohanga o te rīpene. Ka taea hoki te aromatawai i te ngāwari o te kiriata mā te whakamahi i te whakamātautau rīpene. Totorohia te kiriata i mua i te tangohanga o te rīpene, ki te piri tonu ki te papa, he tohu tēnei i te taumata ngāwari tika.
He mea nui kia whai i ngā tikanga whakamātautau tika kia rite ai ngā hua. Me whakarite kia rite ngā āhuatanga o te whakamātautau hanganga kiriata hei whakakore i ngā rerekētanga i waenga i ngā puranga whakamātautau rerekē. Kei roto i ēnei ko ngā tikanga whakarite, te pāmahana, te haumākū, te matotoru o te tono me te wā whakamaroke. Me mahi hoki te whakamātautau rīpene me te pēhanga ōrite kia rite ai ngā hua. Hei tāpiri, me whakataurite ngā taputapu whakamātautau i mua i te whakamātautau. Mā tēnei ka tika, ka tika hoki ngā inenga.

Hei tētahi o ngā wāhanga nui o ngā rauemi hanga hou, he mea nui te kaha hanga kiriata o te RDP ki tana mahi. He mea nui te whakarite kia tutuki te kaha hanga kiriata RDP i ngā āhuatanga e hiahiatia ana hei whakapai ake i te mahi me te roanga o te oranga o te hua whakamutunga. He mea nui te piripono tika ki ngā tikanga whakamātautau kia whiwhi hua ōrite.
