This essay is well writen. However i would prefer if you could add more real life examples of risk assessment . Recent projects for example the BP oil spillage disaster and other previous project failures. Mention how qualitative methods could have prevented this or ways in which they would assess this risks pre happening. In the essay you have described what both risk(qualitative and quantitative) are, but you haven’t related qualitative risk assessment to project planning. You have mentioned you chose it because it is the most popular, however it is better to get into more detail of it as your choice of risk assessment. please let me know if you need further advise on the additional description.
