Arbitration

Correct Answer: Contact a neutral third-party to act as an arbitrator.

The first step in arbitration is 'Contact a neutral third-party to act as an arbitrator'. Here are the reasons why the other answers are wrong: 'Begin negotiations directly with the subcontractor': While this may seem like the logical first step, arbitration has already been decided as the approach to the dispute. It means it is realized that there is a breakdown in communication, understanding or agreement with the subcontractor that requires a neutral third-party to resolve. 'Hire a lawyer and prepare for a lawsuit': This might be a necessary step in some disputes, but it is not the first thing to do while the dispute resolution process has evolved to arbitration. This is a more drastic step which is usually taken when the dispute cannot be resolved through negotiation or mediation or arbitration. 'Bring the issue up in the next team meeting': While transparency is usually a good practice, the quality of subcontractor work may involve information that is not appropriate or beneficial for the whole team to be aware of. Additionally, the team may not possess the necessary skills or authority to resolve the specific dispute.

Correct Answer: Proficient knowledge and experience in the field of programming.

The most important attribute for an arbitrator in this situation should be 'Proficient knowledge and experience in the field of programming'. Given the scenario, the disagreement is related to a technical aspect (programming methodology), thus requiring someone with expertise and experience in the field to make an informed and impartial decision. Although 'Being the most senior in the team', 'Being friendly and approachable', and 'Not being part of the project team' could be beneficial attributes, they don't necessarily contribute to making an informed decision about the programming methodology disagreement.

Correct Answer: The arbitrator's role is to hear the dispute impartially and deliver a binding decision.

The correct answer is 'The arbitrator's role is to hear the dispute impartially and deliver a binding decision.' This is because an arbitrator in any dispute is meant to act impartially. They listen to both sides, analyze the situation based on the facts presented, and then make a decision that is binding on both parties involved. The other answers are incorrect because they either misrepresent or misunderstand the neutral and independent role of an arbitrator. For example, stating that the arbitrator should favor the project manager's position contradicts the basic principle of impartiality in arbitration. The idea that the arbitrator should always suggest a compromise is also incorrect because it's the arbitrator's job to make a decision, not suggest compromises. Similarly, implying that the arbitrator should help with the project until its completion goes beyond the scope of what an arbitrator is supposed to do.
