Classical “Not Invented Here (NIH)” approaches are usually associated with a secretive and highly protective approach to business. Such companies are keenly aware of the risk of disclosure, the danger of handing even the most minor advantage to competitors and the personal career risk of doing something wrong. The default position is usually legally-driven, involving heavy non-disclosure agreements (NDA), concern about only reviewing non-confidential information, invalidating Intellectual Property and not letting junior people loose.
