In a small company or a company that is new to usability testing, the stakeholders can be virtually anyone within that company: the CEO, a UX contractor, product management, and even the quality assurance team. In larger companies, especially those with more experience in usability testing, the stakeholders are often representatives of the in-house UX and UI teams or the product owner, if the company does not have a dedicated UX team.
Whether or not each of these potential stakeholders needs to be involved will be determined by the UX researcher, and is very specific to each company.
