I am only half way done with my online training… but!, I was walking down the road and noticed this gutter draining straight down onto the roof into the next gutter. Is this ok? It seems those shingles would wear pretty quickly.
It’s not ideal but is very common… they should extend to the gutter below or to the grade, never spill on the roof to prevent premature wear of localized shingles.
The property has a partial gutter system. Recommend adding gutters and downspouts where needed.

In a heavy rain I bet there is a fair amount of overflow on any one entering or leaving. Very poor set up.

Hey Nikki - although generally common, THIS configuration is not working. The downspout shoe is likely too short to start with. The water is not dispersing and the lower gutter can’t keep up with the rainwater rush.
You can see water trail staining on the brick siding (left of the front door) which will likely lead to spalling of the bricks and mortar. And there’s probably a significant washout area on the ground below it. And you know where that water will end up.
I would recommend correction of this drainage configuration. Or at least give warning to the client.

To add to this the discharge is across the shingles and not down the shingles. In addition to premature wear of the shingles this can also contribute to water penetration under the shingle edges. If you review the shingle manufacturer installation, best practices documents, and/or warranty they may describe any discharge on the shingles as an unapproved condition.
Unfortunately beyond that there are no authoritative documents that prohibit this type of configuration. It is also common here in Texas and I do write it up whenever seen. One day common sense might actually be used in the building and contracting industry.

Unfortunately that is so true! Another problem are aesthetics over functionality.
