Luc Laroche has decided to hire an external consultant to investigate the problem. Do you think that this is a wise decision or would it have been better to ask his son Davy or an internal consultant to do the research project? It is a wise decision by Luc Laroche, he did the right thing by hiring a professional person. Luc Laroche himself wasn't able to identify the problem, Davy pointed out the issues. But as Davy’s abilities are restricted to the accounts department only. He wasn't sure about taking over the company at that moment. McKinsey Consultant. As his elder son Davy, is basically a field person of accounting. So he would be only able to point out and look after this department particularly. On the other hand, an internal consultant will only be able to examine the company at a micro level. Whereas an external professional consultant 'Paul Thomas Addison' is able to examine the company on a macro level as well. He did a thorough research and after that he was able to identify all the issues such as financing related issues, the legal government regulations for the family business and the overall performance and productivity of the company.
