Prof Christine McCourt, who is leading the review, told BBC Scotland that hearing from a range of people would be valuable in "drawing the right lessons for improvement". The review is expected to report back next summer.
Families had expressed concern that the review would not take into account how they felt failed by the NHS. The Scottish government said the review would consider the "direct experiences of women, families and staff at every level of care".
The review was commissioned after a BBC Disclosure investigation highlighted failings in maternity care across Scotland. In the film, Lori Quate shared his experience of losing his wife Jacqui Hunter in 2020. The review aims to identify lessons and improve services for the future.
