If we considering the assumption and constraints in the project and we need to controls and monitor it .my questions is did this assumption and constraints have validated in the project ?

I am unclear about what you are asking. Constraints and assumptions will be reviewed with the customers. Additionally, you can perform an assumption analysis to review the assumptions and come up with controls and monitoring.

Thanks for your replying what I mean in my question is the constrain in the project is fixed or it can be change throughout the project lifecycle .

Murtada -

We need to distinguish between true and perceived constraints. In the former case, they may represent absolute limits on the project which can't be exceeded. A good example would have been Y2K - short of purposely setting clocks backwards, the date change was going to happen at midnight.

Outside of such absolute constraints, we are usually dealing with "semi-firm" ones. For example, a team might be told there is a hard financial limit on their project, but if push comes to shove, the portfolio governance committee might free up funding from a lower priority project.

I like to get a few bits of info about project constraints:

1. What is their relative priority - for example, is schedule adherence #1 and hence, cost and/or scope can be flexible?

2. What proof do we have that the constraint is firm or are we just making an assumption? If the latter, when and how can we validate it, and how often should we check back to see if something's changed?

Yes, constraints can and often do change. Kiron gave a great example of when it might not change, but those are few. Resources is the most likely factor influencing a constraint change. As an absolute constraint approaches (like time) many project adjust resources to affect the semi- firm constraints to hit that absolute constraint.
Regulation changes also affect constraints are usually outside of the PM's control. However, a change in regulation can make an absolute constraint semi-firm, or create a new absolute constraint.
The shorter the project, the less variability in the constraints.
