See the board of directors.. All are civilians. Fauji Foundation was in huge losses for years even when they had no competition. They needed experts. Unfortunately, those are civvie.
The army can just cut the red tape and provide security. It can't do anything else. Even Suparco, AWC, etc have many civilians, who here given the right opportunities/tools do wonder.
Even putting army personnel in an underfunded and controlled civilian setup cannot give any yield. For example, martial law. Army had everything under command but couldn't develop any civilian setup.
In Ayub era, the westerners directly came and set up institutes like PTV, Steel Mills, etc For sure, there are/were some exceptions.
