He realizes that the only way to win the conflict is to kill both Sollozzo and Captain McCluskey. When his brothers kid him for bein naive and Sonny admonishes him for reacting too personally and emotionally, Michael makes a compelling argument for why killing the two is in the family's business. He concludes by stating, "It's not personal, Sonny. it's strictly business." Not only does this scene demonstrate another example of removing perceived obstacles, it also touches upon parties perceptions and the roles they play in an organizational dispute. Although Michael is new to the business, from what he had seen in the hospital he perceives the problem being Sollozzo and McCluskey, or someone else.

When the obstacle starts to hurt business, it is removed, typically through negotiation. The negotiated resolution will be focused on creating conditions that let all parties continue doing successful and beneficial business.
