The Testing of the initial version is carried out in the third stage to determine what needs to be improved, while the testing of the beta version is carried out during the fourth stage to ensure that all necessary criteria are met.
The process of technological design involves several distinctive processes which can be broken down into four stages.
The four stages involved in the process of technological design are :
- Identify a need : during this process the engineer identifies a problem that needs to be resolved
- design a solution : an initial design is created to provide a solution to the problem identified in stage 1
- Implement the solution : The design is tested and implemented if successful
- evaluate the solution : In this stage the result from the solution ( beta version ) is subjected to ensure that all criteria are met
hence the testing of the initial version is to determine what needs improvement while the testing of the beta version is to ensure all criteria are met
