Explanation
The best way for a business analyst to build trust with stakeholders after making a mistake is to be vulnerable and own their mistake. This will show honesty, humility, accountability, and willingness to learn from errors.
Promising to work harder to avoid other mistakes may sound defensive or unrealistic without acknowledging what went wrong or how to fix it. Asking their supervisor for help immediately may seem desperate or unprofessional without trying to resolve it first with stakeholders.

Explanation
This answer states that using a collaborative influencing style is what the BA should use when presenting their findings to the CMO and other stakeholders after surveying the marketing group about their pain points and discovering that their concerns differ from the CMO's theory about issues with the UX of Campaigns in Salesforce. A collaborative influencing style is an approach that involves working with others to find a mutually beneficial solution or outcome. A collaborative influencing style can help the BA to present their findings to the CMO and other stakeholders by acknowledging their perspectives, sharing relevant data and insights, and seeking their input and feedback. A collaborative influencing style can also help the BA to build trust and rapport with the CMO and other stakeholders, and to facilitate a constructive dialogue and consensus among them.

Explanation
The groups that the business analyst should work with to gain full alignment on a common program vision and strategy are senior leadership, IT leadership, and middle management. Senior leadership are the executives who have the authority and vision for the Salesforce implementation. IT leadership are the managers or directors who oversee the technical aspectsof the Salesforce implementation. Middle management are the supervisors or team leads who manage the sales and service teams. These groups can help the business analyst define the goals, scope, requirements, and success criteria of the Salesforce implementation, and resolve any disagreements or conflicts among them. Business leaders, end users, and executive sponsors are other groups that may be involved in the Salesforce implementation, but they may not have the same level of influence or responsibility as senior leadership, IT leadership, and middle management.
