This is one of the most important aspects of program evaluation because this is an essential criterion that corroborates whether or not the findings of a program are valid. Changes are not an uncommon occurrence when it comes to public health programs. Sometimes programs do not work as planned for multiple reasons and changes need to be made. However, the amount of changes made should not compromise the plan that was set forth before the program began. For example, if a staff member needs to be replaced, due to personal reasons or ineptitude; replacing this person most likely won’t affect the validity of the program because no changes were made to the original plans. On the other hand, if a change is made to the program itself for one reason or another, there is a high possibility that the program’s validity will be compromised. This is mostly because the program lends itself to be affected by external factors that might not be taken into account when the change is made, therefore affecting the outcome (whether for better or for worse) and possibly rendering the results
