Injiniyoyi suna amsawa da sauri kuma suna iya magance matsalolin ba kawai ba, har ma da lamurra masu rikitarwa. Wani lokaci nakan juya musu da tambayoyi: "Shin zai yiwu a yi wannan, kunna shi?" ko "Na saita wani abu a nan, kuma baya son yin aiki. Taimaka!" - za su yi haƙuri su sami jagorar da ake buƙata a can kuma su nuna daidaitattun ayyuka; ba za su amsa ba: "Muna magance matsalolin hardware kawai."
