In law, time constraints [1] are placed on certain actions and filings in the interest of speedy justice, and additionally to prevent the evasion of the ends of justice by waiting until a matter is moot. The penalty for violating a legislative or court-imposed time constraint may be anything from a small fine to judicial determination of an ...
The scope constraint refers to what must be done to produce the project's end result. These three constraints are often competing constraints: increased scope typically means increased time and increased cost, a tight time constraint could mean increased costs and reduced scope, and a tight budget could mean increased time and reduced scope.
Real-time computing (RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. [1] Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".
Some project managers feel that the earned value management technique is misleading, because it does not distinguish progress on the project constraint (i.e., on the critical chain) from progress on non-constraints (i.e., on other paths). Event chain methodology can determine the size of the project, feeding, and resource buffers.
soft constraints: it is desirable that these constraints are met but not meeting them does not make the schedule invalid. Some examples of constraints are: A nurse does not work the day shift, night shift and late night shift on the same day (i.e. no 24-hour duties). A nurse may go on a holiday and will not work shifts during this time.
Another well known example is the cocoon sequence in the film Alien. The scene added a lot of information about the fate of several crew members and new information on the life cycle of the creature, but it was ultimately deleted, as it was thought to slow down and to disrupt the tension of the end of the film.

A constraint is anything that prevents the system from achieving its goal. There are many ways that constraints can show up, but a core principle within TOC is that there are not tens or hundreds of constraints. There is at least one, but at most only a few in any given system. Constraints can be internal or external to the system.
A project is a type of assignment, typically involving research or design, that is carefully planned to achieve a specific objective. [1]An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations".
