The correct answer is 'Yes- partnership sourcing can improve performance which will ultimately satisfy the end customer'. The important thing to note in this Question: is the word 'monopolistic'. This means that there are no alternative suppliers- so the 'no' options are wrong- there are no alternative suppliers and no opportunity to outsource. The other answer is incorrect as sales figures isn't Andrew's concern - it's the complaints and quality of the product. Improving performance to satisfy end customers is therefore his main driver for considering a Partnership. See p. 127 for more information on Drivers of Partnership Sourcing. This comes up a lot in the exam
