A project manager of an IT company is assigned to a project whose schedule may be delayed due to a lack of resources to conclude the backlog activities. The project manager decides to hire additional developers to reduce the project's technical debt and meet the project deadline. What should the risk manager advise the project manager to do to address this situation? Hire as soon as the project metrics trigger a risk response. Immediately hire as soon as the project begins to fall behind schedule. Only hire when it is economically feasible to do so. Only hire if risk response is escalated and approved by the stakeholders
