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.

<span>The results may not generalize well. This is one of the goals of good scientific research: can the results be taken to fit more than just the sterile, controlled situations usually found in the research setting. Many times, it's been found, research tends to lack the ability to be placed in a more "natural" setting.</span>

From the term itself operant conditioning, this is when behavior is being controlled or influenced by a certain consequence. Operant conditioning can be of different types such as positive reinforcement, negative reinforcement, positive punishment, and negative punishment. In Jennifer's case, this can be classified as positive reinforcement since the stimulus being used encourages her to do the same action again in the future.
