add the first two Program Components, Skating Skills and Transitions, belong to the technical side of the equation, along with the base scores, GOEs, levels, and deductions that comprise the TES.
The other three Program Components -- Performance/Exection, Choreography, and Interpretation -- combine to play the role of the old second mark.
If you look at the criteria for Presentation Scores in 6.0,
Harmonious composition of the program as a whole and its conformity with the music chosen
Variation of speed
Utilization of the ice surface
Easy movement and sureness in time to the music
Carriage and style
Originality
Expression of the character of the music
Unison (in the case of pairs skating only)
Explicitly listed in the criteria for PCS:
Skating Skills:
Unison in pairs skating
Variation of speed
Performance/Execution:
Carriage and style
Variation of speed, Variety
Unison and “oneness”
Choreography
Harmonious composition of the program as a whole and its conformity with the music chosen
Utilization of the ice surface
Originality
Interpretation
Easy movement and sureness in time to the music
Expression of the character of the music
Unison and “oneness”
Implicit in criteria for PCS:
Utilization of the ice surface:
Skating Skills: "Multi directional skating," is pretty much required to utilize the ice surface to the full extent; otherwise, the skater is going in circles.
Expression of the character of the music:
Transitions: "Transitions can be short or long, including the use of blade, body, head, arms, legs as dictated by the music."
I don't see why transitions is primarily technical, when it applies equally to choreography. Without skating skills, "Variation of speed," "Utilization of the ice surface," "Easy movement and sureness in time to the music," " Carriage and style" and "Unison (pairs)" are moot, and "Expression of the character of the music" is difficult, but doable, as anyone who has sat through the qualification rounds for European Ladies can attest.
