Explanation
According to the PMBOK Guide, the project manager is responsible for developing the project team by improving their competencies, interactions, and overall performance. One of the tools and techniques for developing the project team is training, which involves providing learning opportunities to acquire new skills or enhance existing ones. Training can be formal or informal, and can be delivered by internal or external sources. In this scenario, the agile project team received an assignment to develop an industrial system that interfaces with robots, which is a new type of work for them. The team members are interested in acquiring such expertise, but it may result in a project delay. The best way to handle this situation is to add an experienced professional to the team to reinforce knowledge sharing and help grow team expertise in the new product. This option provides an informal and internal source of training for the team, as well as a mentor who can guide them through the challenges and complexities of the newtechnology. This can help the team learn faster, improve their performance, and deliver a high-quality product. Creating a separate team, using a robotics vendor company, or hiring a consulting company are not the best options, as they do not address the team's interest in acquiring new expertise, or the project manager's responsibility to develop the team. These options may also introduce additional risks, costs, or coordination issues to the project. References: PMBOK Guide, 7th edition, pages 215-216, 9.5 Develop Team.
