North Koreans are led to believe from a very young age that their unelected rulers, the Kim dynasty, beginning with Kim Il-sung, are essentially infallible. The Kims are elevated to a semi-divine status, to the point that Kim Il-sung is enshrined in the constitution as the Eternal President of the country.
Ever since Kim Il-sung decided to secure his position by competing with the military and visiting various military bases and installations, it has become a tradition for the current ruler, Kim, to visit various sites, show himself around crawling and/or terrorizing local officials, look at various things, and at the same time deliver what the country's official media describe as "field guidance."
This could be an observation about how it would be better if this fish farm produced 20% more fish, or if this lubricant factory could build a new wing to create more industrial lubricant.
Basically, everything the leader says during these visits is written down and then implemented to the extent that the country's resources and technical expertise allow.
North Korean media frequently publish photographs of these field orientation visits that have been cheerfully animated to great comic effect with very little additional effort required, due to the inherently comical nature of a head of state who spends most of his time simply looking at things.
