Which of the following helps to build competence in collaboration?

AgilePM advocates collaboration as a core value, stressing “working together towards a shared goal.” Competence in collaboration grows in cultures that remove fear, encourage learning, and align on purpose. A no-blame culture fosters psychological safety so issues surface early and teams can inspect and adapt without defensiveness. Asking for help is encouraged through active business involvement and empowered, multi-disciplinary teams; it reduces decision latency and improves quality. Setting clear goals—e.g., business outcomes, Definition of Done, and prioritized objectives—creates shared focus, enabling constructive cooperation and trade-offs. By contrast, rewarding individual efforts tends to optimize locally, fragment accountability, and discourage knowledge sharing; AgilePM favors team-based achievement and collective ownership. Agile guidance repeatedly links effective collaboration with facilitation, frequent reviews/demonstrations, and visible progress measures that are team-centered, not individualized. Therefore, the options that genuinely build collaboration are 2, 3, and 4, making D correct.
