sinokubona ukusuka kumfanekiso othelekisekayo, kuyacaca ukuba iimvavanyo ezimbini zivela kokufanelekileyo ukuya kokungafanelekanga. Kufuneka icace gca: umtsi we-SPD wentambo yokuxhuma njengenxalenye ye-SPD, kufuneka ajoyine uvavanyo lwe-SPD kunye, nokuba ithini i-SPD okanye utsibe ucingo ngokude nje ukuba iiparameter zesitayile sokudibanisa zingafanelekanga, ekugqibeleni ziya kugqiba ukuba i-SPD ayifanelekanga. Ke abavelisi be-SPD kufuneka bahlole kwaye bavavanye ucingo lokutsiba oluthenge kwindawo yentengiso.
