1. Nthawi yobweretsera: Kusungirako kwakukulu kuonetsetsa kuti nthawi yochepa yobereka, makamaka masiku 5-7.
2. Kasamalidwe kamitengo: Zothandizira zomwe zilipo komanso luso lakasamalidwe lamitengo titha kupereka zophatikiza zofananira pazofunikira za kasitomala.
3. Chigawo chapamwamba cha mphero: Ikhoza kupereka chiphaso chokwanira ndi zikalata zoyenerera kuti zitsimikizire zapamwamba ndi kupereka chithandizo kwa ma tender.
4. Dongosolo lolimba la QC: Kuyang'ana kwapadziko lonse, kuyesa kwathunthu ndikuwonetsa, kuwunika kwa gulu lachitatu
5. Pambuyo utumiki: mankhwala onse traceable, Kufufuza gwero la udindo
