Learning requires exposure, and let's be honest here, the Pakistani defence industry hasn't gotten a whole lot of it, especially in the shipbuilding and land vehicles areas.
Whether it be by contracting an external vendor to help guide a local one (e.g. in this case where STM will help KSEW), sending Pakistani students to overseas universities for STEM education, picking up consultants with valuable insights and skils, you're going to need to talk to others in order to improve.
Granted, this deal with STM isn't going to flip around KSEW, for that we will need a much more robust and comprehensive policy of indigenization that cuts across acquisitions, education, R&D funding, etc.
