The stage that involves the change and adaptation of a system is upkeep and maintenance.
Developing a new system is a complex process that requires multiple steps and stages. The most important stages are:
- Planning.
- Design.
- Development.
- Testing.
- Upkeep and maintenance.
From these stages, the last one "upkeep and maintenance" is the one that requires adapting the new system that has been already designed. This is the last stage because even after testing the system it is likely this has to be fixed or adapted, the most common reasons are:
- Fails that were not detected during testing.
- Upgrading the sytem.
- Including new features to meet customers' needs.
Based on this, the phase during which the system is fixed or adapted is the upkeep and maintenance stage.

Answer:
Conventional medicine is the one that uses scientific procedures for the diagnosis and treatment of diseases.
Complementary medicine is the one that uses together, conventional medicine and other more traditional medicine, such as beekeeping.

Conventional medicine is in charge of using various medical processes to identify people's illnesses and provide them with the appropriate treatment. It is characterized by the use of pharmaceutical drugs and different medical examinations.
Over time, other types of medicine have also been incorporated, such as complementary medicine that is characterized by using conventional medicine and other alternative methods for diagnosing and treating people's illnesses. And finally, there is an alternative medicine that considers that the best option is optional treatments that do not require pharmaceutical medications but instead use meditation or other techniques to treat diseases.
