2CONSTRCUTION PROJECT MANAGEMENT
Part A
Triple Constraint Model
Triple Constraint model is the most widely used predominant framework that helps
project managers across the globe to monitor, assess and control the organizational processes. It
is a building block that helps to improve project planning and design for businesses (Serrador
and Turner 2015). The Triple Constraint model consists of time, costs and scope as its
constraints where scope is referred to project performance and, cost and time refers to
deliverables of a given project.
The features of Triple Constraint model are that it helps to measure the performance of
the given project, budget estimation of project, schedule estimation of project, quality estimation
of project. The success criteria of Triple Constraint model is keeping correct balance between the
constraints of the project. The critical success factors of Triple Constraint model are
consideration of performance targets in short period in order to generate specified results within
the project budget as well as scheduled time line (DuBois et al. 2015). The key performance
indicator of Triple Constraint model are time management, scope management, quality
management, project performance and budget management. The strengths and limitations of
Triple Constraint model are best evaluated and processed when the result of the project is
compared and contrasted with the expected result of the organizational business processes. The
result of the organizational business processes consists of advantages such as NPV (Net Present
Value), payback analysis, ROI (Return on Investment) and others (Ekrot, Kock and Gemünden
2016). Hence, the comparison of overall advantages involved with the organizational business
processes to the result of the project triangle constraint model implementation. This helps to
evaluate the goals and objectives of the project management triangle constraint model.

The above figure shows that there are three constraints in the Triple Constraint model and
they are time, cost and scope. This are the factors that helps to complete a project for successful
organizational success.
Strengths
The strengths of the Triple Constraint model from control perspective are given below as
follows.
 Measure of performance of the project- The Triple Constraint model helps in assisting
project managers to make effective decisions and controlling of project manager’s
respective projects throughout the execution stage (Silvius and Schipper 2016). This
provides advantages in planning and controlling or project in project management. Thus,
Triple Constraint model has remarkably become the first and foremost measurement
framework to evaluate and improve the performance of the project globally.
 Estimation of project budget- The proper estimation of the budget involved with the
project is done by identifying the different costs related to particular project management
to improve organizational business processes (Heagney 2016). This constraint in Triple
Constraint model helps to identify, assess and understand the budgets and costs related to
respective projects of different project managers.
 Estimation of schedule of project- The estimation of schedule of project is an essential
factor involved with the project. This estimation helps to complete the project at
scheduled time without any delay in time schedule (Joslin and Müller 2015). This
constraint in Triple Constraint model helps project managers to estimate the time
scheduled for a particular project.
 Estimation of quality of project- The proper estimation of quality of project is
necessary for effective outcome of the project. The project quality does not come under
the Triple Constraint model as a constraint, however, project quality is the ultimate goal
and objective of the Triple Constraint model (Serrador and Turner 2015). This can be
shown as, if there is involvement of high cost with the project, then the project will yield
effective project quality. The implementation of resources of low quality in the project
will affect the project success.
