    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 zoyenera kwambiri pazosowa za kasitomala.

    3. Chigawo chapamwamba cha mphero: Ikhoza kupereka chiphaso chokwanira ndi zikalata zoyenerera kuti zitsimikizire zapamwamba ndikupereka chithandizo kwa ma tender.

    4. Dongosolo lolimba la QC: Kuyang'ana kwapadziko lonse, kuyesa kwathunthu ndikuwonetsa, kuwunika kwa gulu lachitatu
