  • Does not account for the fact that requirements constantly change.
  • It also means that customers can not use anything until the entire system is complete.
• The model makes no allowances for prototyping.
• It implies that you can get the requirements right by simply writing them down and reviewing them.
• The model implies that once the product is finished, everything else is maintenance.
