I think a lot of the ideas and lessons from doing external pro launches can be applied internally. For example, this feeling of accomplishment and team identity can absolutely be magnified by doing an internal proc launch. Stright actualy had this really cool thing called shipped at shiped out, where people would rite when they had release of new capability. It was especially useful for internal releases because there was no ukno blog or twitter that they could post do. And i always found that very focusing and rewarding to articulate to the company what you've done, why and what benefits theyre gon frentyou have.
