The verb consists of 'schief' (crooked, askew) and 'laufen' (to run, to go). Literally, it therefore means 'schief laufen' (to run/go crookedly). This figurative origin helps you remember the meaning 'misslingen' (to fail/go badly) or 'fehlschlagen' (to fail).
Ich hoffe, bei meiner Prüfung läuft nichts schief.
I hope nothing goes wrong in my exam.
'Schieflaufen' (to go wrong) is a separable verb. In a main clause, the prefix 'schief' stands at the end of the sentence. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Bei unserem Experiment lief etwas schief.
Something went wrong with our experiment.
The perfect tense of 'schieflaufen' (to go wrong) is always formed with the auxiliary verb 'sein' (to be), since it is derived from 'laufen' (a verb of movement). So the correct form is 'es ist schiefgelaufen' (it went wrong).
Leider ist bei der Buchung etwas schiefgelaufen.
Unfortunately, something went wrong with the booking.
The verb is very often used impersonally or with indefinite subjects such as 'etwas' (something), 'nichts' (nothing), or 'alles' (everything).

For an unsuccessful project, scheitern and schieflaufen can both fit. Scheitern usually describes the final failure to achieve the goal, while schieflaufen emphasizes that the process is not going as planned and may still be corrected. Use scheitern for the result and schieflaufen for the problematic course of events.
