Which of the following is a core component of OneStream's implementation framework?

User training sessions are indeed a core component of OneStream's implementation framework. Effective training ensures that end-users are well-equipped to navigate and utilize the features of the OneStream platform. By providing structured training sessions, organizations can facilitate the knowledgeable use of the software, empower users to maximize its features, and support the overall adoption of the new system within the organization.

In the context of OneStream implementations, user training sessions are critical for ensuring that users have the necessary skills and understanding to leverage the system effectively for reporting, data analysis, and financial management. They help users transition smoothly from legacy systems and minimize resistance to change, thereby contributing to a successful implementation.

The other options may play roles in the overall implementation process, but they do not represent the foundational elements of the OneStream implementation framework in the same way that user training does. Project kickoff meetings can assist in setting the stage for a project, while custom software development and standard template creation can be important for meeting specific business needs, but they fall outside the core focus of ensuring user competency and system adoption, which is what user training sessions directly address.
