Mazo pakalpojumu sniedz\u0113ji ir nabag\u0101ki nek\u0101 lieli, provinc\u0113lie ir nabag\u0101ki par galvaspils\u0113tas pakalpojumu sniedz\u0113jiem, vi\u0146iem ir maz\u0101k resursu att\u012bst\u012btas infrastrukt\u016bras izveidei.

<\/p>\n

Ja run\u0101jam par apr\u012bkojumu, tad pagaid\u0101m iesp\u0113jas paliek visai pietic\u012bgas. Lai ieg\u0101d\u0101tos jaunu sakaru tehniku, ir nepiecie\u0161ams atrast papildu l\u012bdzek\u013cus.

<\/p>\n

V\u0113l viens svar\u012bgs aspekts ir pakalpojumu l\u012bmenis. \"Darba sp\u0113ka tr\u016bkums\" nav tik bie\u017ei sastopams.

Un tad spriedumi par to, ka \"kur vi\u0146i (klienti) no mums aizb\u0113gs?\" k\u013c\u016bst par galveno dev\u012bzi klientu apkalpo\u0161an\u0101.<\/p>\n
