What is the Triple Constraint?
The triple constraint of project management is the balance of the project’s scope, time and cost. Triple constraint is used to determine whether or not a project’s objectives are being met. During the planning phase of a project, a project manager will define the scope, time, and cost of a project. As the planning phase continues, the project manager discovers that there may be some changes or adjustments needed in the project’s scope, time and/or cost. When one aspect needs change or adjustment, then it directly affects one of the other factors of the triple constraint. For example, if the cost increases, it is logical to assume that the scope and time will increase as well. Or, if the cost decreases, one can assume that the scope and time will decrease. This rings true for scope and time as well. A project manager must be thorough and detailed in planning the scope, time and cost of a project in order to maintain the constraint or be prepared to fluctuate with it. Adjustments can be made during the project for various reasons to include changes made by the client as well. It is the project manager’s responsibility to be aware of the changes and how they will affect all aspects of the triple constraint and be prepared to modify each aspect accordingly.
Scope
The scope of the project is what is actually included in the project as well as what is to be excluded. A project’s size, how complex it is and its importance all affect how much effort goes into scope planning. Defining the scope of a project is important in determining the success of the project. A detailed scope overview and statement is the basis for project decisions. It helps those involved understand exactly what the outcome of the project will look like and what is to be expected. Let’s say we have a client who wants to launch an inspirational Tshirt company. This client wants to produce,...
...THEORY OF CONSTRAINTS
The Theory of Constraints (TOC) is a management philosophy where three financial
measures of profit, return on investment (ROI) and cash flow are presented. All three of
these measurements are necessary. First, we need an absolute measurement of profit, the
amount by which revenues exceed expenses. Second, we need the relative measurement of
ROI that compares the amount of money made relative to the amount invested. Finally, we
must have...

...Project Constraints
There are several areas of constraints identified on this project. These constraints will be considered when developing work packages and allocating the resources to these packages.
1. Resource constraints
Due to the functional arrangement of the present organization structure of the MOWI, staff resources will only be available on a part time basis for this project
The client has limited staff capable of...

A Pythagorean triple is a triple of positive integers a, b, and c such that a right triangle exists with legs a, b, and hypotenuse c (Bluman, 2005). A Pythagorean triple is a triple of positive integers (a, b, c) where a2 + b2 = c2. A triple is simply a right triangle whose sides are positive integers. An easy way to generate...

Pythagorean Triples
Pythagorean Theorem states that the sum of the areas of the two squares formed along the two small sides of a right angled triangle equals the area of the square formed along the longest.
￼
If a, b, and c are positive integers, they are together called Pythagorean Triples.
The smallest such Pythagorean Triple is 3, 4 and 5. It can be...
