Develop a suitable Risk Breakdown Structure (RBS) for the Coventry rail station project and connect each of the risks in the risk register to this RBS. Present a summary of this in your report (not the entire list) and give a clear justification for your choice of RBS. Make a Likelihood-Impact matrix where all risks from the risk register are represented (You do not need to mention each Risk ID specifically, generic symbols, eg. , suffice). Using your Likelihood-Impact matrix, rank the categories in the RBS from most to least important, and explain your reasoning.
