I want you to create a product requirements document in markdown format For a SAAS web application that will be used for conducting BowTie risk analysis.
So that you understand what BowTie risk analysis is, you should review the following sources of information:

1. Example of the BowTie Methodology - https://www.wolterskluwer.com/en/solutions/enablon/bowtie/expert-insights/barrier-based-risk-management-knowledge-base/the-bowtie-method
2. Example of a similar Software application - https://www.wolterskluwer.com/en/solutions/enablon/bowtie/bowtiexp

The application must have a modern feature-rich browser client user interface, which is supported by a backend server with the core database functionality.
The application will have integrated AI support for creating the BowTie risk analysis, and which is also editable by end users manually.

Do not start coding yet or creating the PRD, we are going to collaborate on the development of the PRD.
