Note the assumptions and constraints that affects the project


Assumptions are factors considered in planning phase to be true, real, or certain and involve a degree of risk (e.g.: if an activity needs a special equipment, the project manager may assume that it will be available).

Constraints are restrictions that affects the performance of the project. The most popular constraint is the budget, that limits the scope, staffing and schedule.
Both assumptions and constraints must be taken into consideration in all aspects of the project planning.
