The project manager could have avoided higher baseline costs by verifying applicable budget inputs related to the project. This involves establishing a baseline that clearly describes the project scope, cost, and schedule1. If deviations from the baseline become necessary, project managers must follow an agreed-upon protocol for communicating issues, determining next steps, and making changes to the plan1. Cost estimation is critical for success in project management because every project manager must estimate all project costs before creating a project budget2. If the project budget is insufficient, it's very likely to face cost overrun2. References:

According to the PMBOK Guide, 7th edition, one of the key activities of the project manager is to tailor the project delivery approach based on the project characteristics, context, and environment. This means that the project manager should select the appropriate tools, techniques, methods, and artifacts that best suit the project needs and objectives. If the project manager realizes that the project will benefit from using adaptive tools, such as agile or hybrid methods, then the project manager should update the project documents accordingly and plan the first iterative session. This will enable the project team to deliver value incrementally and iteratively, and to respond to changes and feedback more effectively. Option A is the best answer for this question.
Option B is not the best answer because contacting the project sponsor and requesting new team members who are familiar with adaptive projects is not the first thing that the project manager should do. It is a possible action that the project manager may take if the current team lacks the skills or experience to work with adaptive tools, but it is not a necessary or immediate action. Moreover, requesting new team members may not always be feasible or desirable, as it may increase the project costs and risks, and may disrupt the team dynamics and performance.
Option C is not the best answer because confirming team capabilities before introducing adaptive tools and artifacts to the project is not the first thing that the project manager should do. It is a good practice to assess the team's readiness and ability to work with adaptive tools, but it is not a prerequisite or a determinant for tailoring the project delivery approach. The project manager should base the decision on the project characteristics, context, and environment, not on the team capabilities. Moreover, confirming team capabilities may not always be accurate or reliable, as the team may have different levels of familiarity and confidence with adaptive tools.
Option D is not the best answer because freezing the design stage and looking for an external resource to run iterative design at extra cost is not the first thing that the project manager should do. It is a possible action that the project manager may take if the project is too complex or uncertain to be handled by the internal team, but it is not a recommended or proactive action. Freezing the design stage may delay the project delivery and may not reflect the current or future state of the project requirements or stakeholder needs. Looking for an external resource may increase the project costs and risks, and may reduce the project control and quality. References:

According to the PMBOK Guide, project completion involves verifying that all the project deliverables meet the acceptance criteria and obtaining formal acceptance from the customer. Sometimes, the customer may request changes or modifications to the deliverables, which may affect the project scope, schedule, cost, or quality. In such cases, the project manager should negotiate with the customer to reach a mutually satisfactory agreement that balances the project objectives and the customer expectations. Negotiation is the process of conferring with others to come to terms with them or reach an agreement. The first step in negotiation is to analyze the bounds of the negotiation, which means to identify the best alternative to a negotiated agreement (BATNA), the worst alternative to a negotiated agreement (WATNA), and the zone of possible agreement (ZOPA) for both parties. BATNA is the most advantageous alternative course of action a party can take if negotiations fail and an agreement cannot be reached. WATNA is the worst outcome that a party can expect if negotiations fail. ZOPA is the range of possible outcomes within which an agreement can be reached by both parties. By analyzing the bounds of the negotiation, the project manager can determine the minimum and maximum acceptable outcomes for both parties, and use them as a reference point for making offers and counteroffers. This can help the project manager to avoid deadlock, impasse, or unfavorable outcomes, and to achieve a win-win situation. Therefore, option A is the best answer.

Kanban method offers a simple and effective way to manage your tasks and projects. It is based on two rules:
visualization of workflow and limitation of the number of tasks being in progress at a time. By following these two principles, you save time which you'd normally spend on getting organized, and can perform your tasks much quicker.

For a globally distributed project team, effective collaboration is crucial. The project manager should:
* C. Review the communications strategy with the team regularly with a view for continuous improvement. This ensures that the communication approach remains effective and adapts to the changing needs of the project and its stakeholders. Regular reviews can lead to enhancements in the communication process, making it more inclusive and efficient1.
* D. Send out a survey to review the preferred method, time frequency for communications. By understanding the preferences and constraints of the global team regarding communication methods and timing, the project manager can tailor the communication plan to suit everyone's needs, thus fostering better collaboration2.
* E. Compile a communications management plan with input from all stakeholders and distribute for review and approval. A comprehensive communications management plan that considers the input from all stakeholders ensures that everyone is on the same page and that the communication needs of the project are met. This plan should detail the information needs of the project's stakeholders, including what information will be communicated, how it will be communicated, when it will be communicated, and by whom3.
