Exam PSM-III Topic 1 Question 24 Discussion

When Developers raise the lack of certain knowledge or expertise as an impediment, the Scrum Master must address the situation in a way that reinforcesScrum principles, especiallycross-functionality, empiricism, and self-management, while also supporting value delivery.
First, it is essential to verify whether this is truly animpediment. In Scrum, an impediment is something the team cannot resolve on its own. As a Scrum Master, I would facilitate a discussion with the Developers and, if appropriate, the Product Owner to inspect whether the expertise is genuinely required to achieve the desired outcome. In some cases, the scope or approach can be adapted, or the Product Backlog Item can be refined so that alternative solutions are viable. This conversation may reveal that the need for specialized knowledge is less critical than initially assumed.
Second, if the expertise is indeed necessary, the Scrum Master should encourage the team to address the issue as across-functional Scrum Team. Scrum expects teams to have, or acquire, all skills needed to deliver value. Therefore, I would ask the Developers how they couldlearn or acquire the necessary knowledge themselves. Possible options include allocating time for learning, research, training, experimenting, or building a prototype. These activities can be planned as part of the Sprint Backlog and support long-term team capability.
Third, the Scrum Master can help the team make effective use ofoutside expertise without undermining self- management. During Sprint Planning or refinement, the team may consult internal or external experts to gain insights, validate approaches, or reduce uncertainty, while still retaining ownership of the work and the Sprint Backlog.
Finally, if none of these options resolve the impediment, the Scrum Master has a responsibility tohelp the organization support the Scrum Team. This may involve facilitating access to expertise from elsewhere in the organization or, if necessary, from outside the organization. The Scrum Master does not solve the problem personally but works to remove organizational barriers so the team can proceed.
