One lesson, imo, is the cost of outsourcing critical services, that are difficult to quantify, when comparing the cost of doing something in-house or not. Had the security guards been part of the team working at the museum (instead of a rotating team covering multiple clients), they would likely have absorbed knowledge and had an immediate reaction to the missing pieces. The thieves were still moving around the streets with the paintings on a night without much traffic while the security guards were unsure whether a theft had occurred. Had the police begun canvassing the area immediately, they likely would have been caught or at least become suspects immediately. Instead of weeks later.
