After creating a value measurement framework, you want to let program managers know how to measure value with the framework. Where should you document training guides?

Portfolio Process Assets are the repository for portfolio-specific processes, procedures, templates, lessons learned, and training materials; a training guide for the value measurement framework is a portfolio-level process artifact and should be stored here so it remains accessible to portfolio program managers and stakeholders.

The PMIS (Portfolio Management Information System) is a tool for collecting, integrating, and reporting portfolio data and metrics, not for storing process training documentation.

Portfolio Reports are formal communication outputs shared with stakeholders to convey performance and status; they are not repositories for internal process training materials.

Organizational Process Assets are the broader enterprise-level repository; while related, training materials specific to a portfolio's value measurement framework are more appropriately stored at the portfolio level in Portfolio Process Assets.
