Apa care nu aduce venituri:de la proiecte la proceseAugust 2015

Dezvoltarea unui program de management al pierderilor: 5 etape

faza 1: date corecteFaza 2 studiu de bazaFaza 3: siguranta datelorfaza 4: proiecteFaza 5: procesele de afaceriDezvoltarea unui program de management al pierderilor : consolidarea imbunatatirilor (etapele 4 si 5)

Panta: ceea ce vrei sa obtiiProcese de afaceri &Proceduri Operationale StandardInstrumentele de interventie ale unui program activ de management al pierderilor reale

Instrumentele de interventie ale unui program activ de management al pierderilor aparente

Standardul International al Balantei de Apa (WB-EasyCalc versiunea 4.05)In care etapa este programul de management al pierderilor (pentru fiecare din cele 8 instrumente de interventie) in cadrul companiei dumneavoastra?NRW ca parte a randamentului veniturilor totale generate in cadrul Operatorilor RegionaliRandamentul venitului total generat=Randamentul retelei (1 NRW): procentul apei facturate (fata de intrarile in sistem)xRandamentul colectarilor: procentul facturilor care sunt plaite (fata de facturile emise)=Procentul de apa produsa care este transformata in incasariInstrumentul MIS pentru monitorizarea randamentului in Rwanda

ConcluziiAdesea, evaluarea Apei care nu aduce venituri este o ghici-mare, mai mult o ARTA decat o STIINTA exacta Apa care nu aduce venituri este provocarea numarul 1 a utilitatilor de apa Utilitatile ar trebui sa lupte sa fie/sa ramana in controlUtilitatile ar trebui sa fie mai proactive decat reactiveIndentificarea cauzelor componentelor NRW, dezvoltarea planurilor de actiune si consolidarea realizarillor prin Proceduri Operationale Standard imbunatatiteProgramele de management al pierderilor NRW necesita timp & resurse Apa care nu aduce venituri necesita atentia managementului + a tuturor angajatilor
