Blackblot^® Product Management Expertise™

• "Product management does not write requirements."
• "Requirements are a technical description of the solution."
• "User stories are a form of requirements."
• "There are user requirements, customer requirements, business requirements, and marketing requirements."

Let's deconstruct the different misconceptions in these statements.

Requirements are a solid and proven technique that describes and corresponds to the three elements of the product delivery process (planning, definition, development).

There are only three types of requirements:

1. MARKET Requirements describe the market problem
2. PRODUCT Requirements describe the solution
3. TECHNICAL Requirements (aka Tech. Specs) describe how to build the solution

The PMTK Product Planner (aka Product Manager) owns the problem space and is thus responsible for writing market requirements.

Product and technical requirements are written by roles in product development, in the solution space.

Use cases describe how different personas put a solution to use, under which circumstances and for what goals. User stories are a simplified version of the 1960's classic use case.
