As a project manager working with diverse projects in Edinburgh, you must determine whether your organisation is to build a new £120m plant to enable it to produce a new range of remotely controlled air conditioning systems or whether you should upgrade the existing plant at a cost of £50m. Your financial people have calculated that if you build a new plant, you have a 60% chance of earning £200m if there is a strong demand as opposed to earning £90m if there is a weak demand. They have also told you that if you upgrade the existing plant, you have a 40% chance of earning £60m on weak demand and you expect to earn £120m on strong demand. 
Use decision tree analysis to calculate the expected monetary values for each case and recommend as to which option you would endorse.
