Across
  1. 3. Stage where the new system is introduced
  2. 4. Final stage where the system is reviewed
  3. 6. Research method using written questions
  4. 7. Validation check to ensure data is within limits
  5. 8. Information produced by a system
  6. 10. Stage where input, output, and file structures are planned
  7. 13. Implementation method introduced in stages
  8. 16. Stage where the system is created and coded
  9. 17. Type of documentation for programmers
  10. 19. Validation check to ensure data is entered
  11. 20. One-to-one questioning method
  12. 21. Data entered into a system
  13. 22. Work carried out on input data
Down
  1. 1. Type of documentation aimed at end users
  2. 2. Automatic checks to ensure data is acceptable
  3. 5. Research method involving watching users
  4. 9. Implementation method where old and new run together
  5. 10. Written information explaining how a system works
  6. 11. Validation check for number of characters
  7. 12. Implementation method used in one location first
  8. 14. Existing paperwork used to study the system
  9. 15. First stage where the current system is studied
  10. 16. Implementation method where old system stops immediately
  11. 18. Process used to check the system works correctly
