Kuri cranes z'imiterere isanzwe n'imiterere isanzwe, muri rusange bifata iminsi 15; Kuri cranes zifite toni nini, ibisobanuro byihariye cyangwa urwego rwo hejuru rwo gutunganya, bifata iminsi 45 - 60.

Twiyemeje guha abakiriya serivisi zijyanye n'igihe kandi zinoze nyuma yo kugurisha. Nyuma yo kwakira raporo y'amakosa y'umukiriya, tuzagusubiza ako kanya. Ku makosa rusange, tuzatanga ubuyobozi bwa kure hifashishijwe uburyo nka terefone na videwo kugira ngo dufashe abakiriya gukemura amakosa vuba bishoboka. Ku makosa asaba kubungabunga aho hantu hantu, tuzategura abakozi ba serivisi begereye nyuma yo kugurisha kujya ku rubuga hakurikijwe intera iri hagati y'aho umukiriya aherereye. Mu bihe bisanzwe, abakiriya bo mu gihugu bashobora kwitega ko abakozi ba serivisi bazagera aho hantu mu masaha 24, n'abakiriya bo mu mahanga mu masaha 48.

Muri rusange igihe cy'amezi 12 cy'ubwishingizi bw'ibicuruzwa byacu ni amezi 12. Mu gihe cy'garanti, tuzatanga serivisi zo kubungabunga ku buntu, harimo gusimbuza ku buntu ibice byangiritse no kubungabunga ku buntu no gukosora.

Nyuma yo gushyiramo irangiye, tuzakora igenzura ryimbitse rya crane kugirango turebe ko ibipimo byose byimikorere byayo byujuje ibisabwa n'ibipimo by'imikoreshereze y'ibishushanyo mbonera n'ibipimo by'imikoreshereze y'ibicuruzwa.

Igihe cyo gushiraho crane nto ni iminsi 3-7; Igihe cyo gushiraho crane yo hagati ni iminsi 10-15; Igihe cyo gushiraho crane nini cyangwa yateguwe ni kirekire kandi gishobora gufata iminsi iri hagati ya 20 na 30.
