It does not matter, no. A good example is the Bell state of two qubits, $$\left| \text{Bell} \right\rangle = \left( \left| 00 \right\rangle + \left| 11 \right\rangle \right)/\sqrt{2} \, ,$$ in QI notation where $Z \left| 0 \right\rangle = \left| 0 \right\rangle$ and $Z \left| 1 \right\rangle = - \left| 1 \right\rangle$.
Suppose we prepare this state and send one qubit to Alice and the other to Bob, who may be arbitrarily far apart. The way I think about measurements is described here in the case of qubits. This method follows from Stinespring dilation (see also Figure 1 of this work for a nice picture). Intuitively, it's the many-worlds picture of measurement.
When a quantum system is measured, the system becomes entangled with the measurement apparatus in a particular way. Let's imagine measuring some operator $A$ on a qubit, where $A$ has two eigenvalues, $a^{\,}_{\pm}$. Then we can write this observable as $$ A \, = \, \sum\limits_{\pm} \, a^{\,}_{\pm} \, \mathbb{P}^{\,}_{\pm} \, , $$ where $\mathbb{P}^{\,}_{\pm}$ projects onto the eigenstates of $A$ with eigenvalues $a^{\,}_{\pm}$ (i.e., $A \, \mathbb{P}^{\,}_{\pm} = a^{\,}_{\pm}\, \mathbb{P}^{\,}_{\pm}$).
If the qubit is initially in the state $\left| \psi \right\rangle$, after measuring $A$, the state becomes $$ \left| \psi \right\rangle \, \to \, \sum\limits_{\pm} \, \left( \mathbb{P}^{\,}_{\pm} \,\left| \psi \right\rangle \right)^{\,}_{\rm ph} \otimes \left| \pm \right\rangle^{\,}_{\rm out} \, , $$ where the state $\left| \pm \right\rangle^{\,}_{\rm out}$ is the post-measurement state of the measurement apparatus, and encodes the measurement outcome (btw, the $\pm$ states are orthonormal). Also note that $\mathbb{P}^{\,}_{\pm} \,\left| \psi \right\rangle$ is simply the unnormalized collapsed wavefunction for the physical qubit given that outcome $\pm$ was observed. However, in this picture, the expression above is already normalized!
Basically, measurement entangles the apparatus / observer with the system along a particular outcome. Now, suppose Alice measures $Z$ on her qubit. The Bell state is updated according to $$\left| \text{Bell} \right\rangle \to \left( \left| 00 \right\rangle \otimes \left| 0 \right\rangle^{\,}_A + \left| 11 \right\rangle \otimes \left| 1 \right\rangle^{\,}_A\right)/\sqrt{2} \, ,$$ where the $A$ subscript denotes the qubit that encodes the outcome of Alice's measurement. If Bob then measures, the state becomes $$\left| \text{Bell} \right\rangle \to \left( \left| 00 \right\rangle \otimes \left| 0 \right\rangle^{\,}_A \otimes \left| 0 \right\rangle^{\,}_B + \left| 11 \right\rangle \otimes \left| 1 \right\rangle^{\,}_A \otimes \left| 1 \right\rangle^{\,}_B \right)/\sqrt{2} \, ,$$ where the $B$ state labels Bob's outcome.
Importantly, nothing drastic happened to the physical state of the two qubits. And performing these operations in either order (or simultaneously) gives the same result. This is most clear from noticing that everything is invariant under relabelling $A \leftrightarrow B$. Not that you asked, but there's also (1) no collapse required, (2) nothing nonlocal happens (the coupling event is local involving the qubit being measured and the measurement apparatus only), and (3) no information is sent upon measurement.
Even if Bob knows he shares this particular Bell state with Alice, there is no operation he can perform on his qubit to tell whether or what she measured, nor her outcome. If he also knows she intends to measure $Z$, there's nothing he can do to tell whether she measured yet. The reason is physical: The order of measurements does not matter. No information is transferred.
As an aside, suppose Bob intends to measure $X$ instead. If we write the same Bell state in the $Z$ basis for Alice and the $X$ basis for Bob, it is instead $$\left| \text{Bell} \right\rangle = \frac{1}{2} \left( \left| 00 \right\rangle + \left| 01 \right\rangle +\left| 10 \right\rangle - \left| 11 \right\rangle \right) \, ,$$ where the two numbers mean different things. However, because the state is written in the measurement basis, the same thing happens. After both measurements (in either order), we have $$\left| \text{Bell} \right\rangle \to \frac{1}{2} \left( \left| 00,00 \right\rangle + \left| 01,01 \right\rangle + \left| 10,10 \right\rangle - \left| 11,11 \right\rangle \right) \, ,$$ where the digits before the commas inside the kets are the physical state of both qubits (in the $Z$ and $X$ basis for Alice and Bob, respectively), and the digits after the commas are the recorded outcome. Again, the measurement devices are simply entangled with their respective qubits. Nothing drastic happens, no information can be extracted, and the order of measurements is unimportant.
