These circumstances/factors range primarily from hardware, to software, to the human element and many others; however, nobody is expert or even conversant in the intricacies of all aspects of modern technology, hence such procedures as the "Party to the Investigation" system utilized by the NTSB (USA) and others. The "Party" system employed by the NTSB, for example, relies heavily upon outside expertise, and the NTSB Investigators themselves have their specialties such as "Power Plant", Weather", "Structures", "ATC" etc. As you suggested in your above statement, to reach an understanding of complex factors in an investigation, requires the input of many competent individuals.

I'm sure I read in an initial report of the Ethiopian accident, the crew left/forgot to reduce power after takeoff. Whatever any MCAS problems, leaving full power on until you make a hole in the ground is not good practice?
