On of the first steps you should take when considering any kind of advanced literature review is determining what kind of review to choose. This can be complicated but your research question, goal of the study, size of team, and timeline can be very useful in narrowing your choices. For example, on average, a true systematic review being used to change real world practices using a focused question and comprehensive/reproducible search can be accomplished in 12-18 months with a team of 3 or more people.
