Merits of bottom-up technique


  • The details of the sub-problem solutions are available in advance in the form of bottom level modules.
  • The individual sub-problem solutions are designed with great details.
  • The main solution can be planned later depending on the available sub-task solutions.
  • The main solution is used to link all the sub-problem solutions.
  • The sub-solutions obtained are simple
  • A complex main module is designed later using these simpler solutions.
  • This technique is more general and code are reusable.
  • This technique simplifies maintenance and the new features can be added easily.
  • This decision of the final solution can be delayed to make it more effective for implementation.
  • Testing in this case is simple and test cases can be designed very easily.
