Which tool is leveraged by Cisco business architects for describing, visualizing, assessing, and changing business models?

"Business model visualization" is a generic term describing the act of visualizing, not a specific tool.

"Business model framework" is a broad category, not a specific tool with a defined structure.

"Business model agenda" refers to a list of topics or priorities related to a business model, not a tool for its description and analysis.

The Business Model Canvas is a well-known strategic management template used for developing new or documenting existing business models, providing a visual chart with elements describing a firm's or product's value proposition, infrastructure, customers, and finances. It is widely adopted in business architecture and innovation practices, including by professionals like Cisco business architects, to systematically analyze and design business models.
