The B2B buying process is Product specification.
Step-by-step explanation:
A product specification (also known as product specifications) is a documentation with a set of criteria which provides the necessary information by the product teams to develop new features or functions.
A strong spec does not handle product development micro-management. It instead presents the consumers with specific backgrounds, business needs and other parameters that enable them to determine informally when they design and develop a solution.
For examples, when a PSD outlines the user login page specifications and the standard security needs, a PRD version explains the standard security needs in detail.
