  The measurement problem is seen as an ambiguity of quantum mechanics, or,
beyond that, as a contradiction within the theory: Quantum mechanics offers two
conflicting descriptions of the Wigner's-friend experiment. As we argue in this
note there are, however, obstacles from within quantum mechanics and regarding
our perspective onto doing physics towards fully describing a measurement. We
conclude that the ability to exhaustively describe a measurement is an
assumption necessary for the common framing of the measurement problem and
ensuing suggested solutions.
