Management would like you to front-load the requirements with the most risk requirements.

Risky requirements are those that have a high probability of causing problems or failures in the project. By addressing them early in the prioritization, the project team can identify and resolve any issues before they affect the rest of the requirements or the project deliverables. This way, the project can avoid rework, delays, and cost overruns that may result from risky requirements. References: CBAP / CCBA Certified Business Analysis Study Guide, Chapter 6: Requirements Analysis, page 203. Certified Business Analysis Professional (CBAP®) Handbook, page 6.
