How long does the tech spec remain?

On the one hand, the Requirements Specification cannot die. The specification of requirements is a direct expression of the essence of a systematic approach and thinking. The more complex the system, the more accuracy and care required when making any changes. And the created systems do not become easier... 

On the other hand, the Facts are a stubborn thing - honest process/architectural work with a cascade of formed specifications, classic As-Is To-be transitions come across much less often, from start-ups unicorns are born, and certainly there weren't any specifications in them... 

We invite you to a discussion at the round table: 

• Influence of two paradigms on Business and System Analysis: design and product. 
• How to move from one paradigma to another with minimal personal and organizational losses.
