• Minkälaisiin ongelmiin olette törmänneet?
• Mitä toimintatapoja olette havainneet hyviksi?

• Aiheet
• business goals, main domain concepts
• user groups
• functional requirements, non-functional reqs.,
  contraints

• List identified requirements shortly
• Group related requirements
• Analyze the listed requirements very roughly from
  three viewpoints
• Importance for customer must, essential,
  conditional
• Impact to architecture high, medium, low
• Development effort high, medium, low

• Well-documented requirements
• decrease interpretation
• are a contract i.e. official statements of
  requirements)
• are a communication tool
• are a collective memory
• guide design
• guide testing
• are a basis for iteration and project planning
