According to the PMBOK Guide, 6th edition, section 5.6.2, the project manager should perform an impact analysis when a change request is received, to assess the potential effects on the project scope, schedule, cost, quality, resources, risk, and other aspects.3
The project manager should also communicate the impact analysis to the relevant stakeholders, such as the project sponsor, the product owner, the customer, and the team, to facilitate the decision making process and obtain their agreement on the change.3
The project manager should not accept or reject the change request without performing an impact analysis, as this may lead to unrealistic expectations, missed deadlines, scope creep, or stakeholder dissatisfaction.3
The project manager should not ask the product owner to prioritize the new request without performing an impact analysis, as this may disrupt the agile team’s work and compromise the quality of the deliverables.4
The project manager should not call the stakeholder to tell them that the final product schedule must be extended without performing an impact analysis, as this may damage the trust and relationship with the stakeholder and cause them to lose confidence in the project.
