The project management triangle is a model in project management that shows

how the balance between three constraints—scope, time, and budget—affects

the quality of the project. The triangle shows that affecting one constraint will

mean adjusting one or both of the others in order to maintain the quality. It’s

also called the triple constraint model or the iron triangle. Project managers

must oversee all three of these constraints in order to complete a project

successfully.

Let’s say that you need to expand the scope of a project. This might mean

extending the original schedule of the project, or increasing the budget in order

not to affect the quality of the output. Likewise, shortening the schedule to meet

an earlier deadline might mean increasing the budget or tightening the scope.

Need to absolutely reduce the budget and timeline without changing the scope?

Then the triangle might have to shrink—meaning the quality of the product

might be reduced.

Project management triangle: Why it matters

The project management triangle is a useful concept for project managers for the

following reasons:

It helps to see how changing one project constraint will affect other

constraints. If you change the scope of a product you’re hoping to launch, you know

that either the budget needs to increase, or the timeline needs to be extended (or

both).

It can help mitigate risks. Say your project to launch a new piece of software has a

hard deadline, and you’re worried your engineers will fall behind. You can ask

stakeholders for a contingency budget, just in case you need to hire another engineer

to help complete tasks.

It can clarify priorities in a project. Does your project have a hard deadline, a

strict budget, or very specific deliverable requirements? Knowing this can give you a

better idea of what a successful project will look like.

PLANNING

PLANNING

a. The first task of planning is to establish the objectives to be achieved in a project.

The following is a list of possible objectives:

 successful completion of a project; this means

 on time

 within budget

 in compliance with contract documents and specifications.

 improved productivity

 improved or new construction technology

 improved public relations

 improved/changed company image

b. Once the objectives are established, a plan must be developed aimed at meeting

these objectives.

There are many methods and techniques for the planning and scheduling in use:

 Bar chart

 NETWORK (CPM)

 Line of balance etc.

Ø And there are also many package programs such as Microsoft Project, Primavera etc.
