<P> In practice, however, trading between constraints is not always possible . For example, throwing money (and people) at a fully staffed project can slow it down . Moreover, in poorly run projects it is often possible to improve budget, schedule or scope without adversely affecting quality . </P> <P> The Project Management Triangle is used to analyze projects . It is often misused to define success as delivering the required scope, at a reasonable quality, within the established budget and schedule . The Project Management Triangle is clearly insufficient as a model of project success because it omits crucial dimensions of success including impact on stakeholders, learning and user satisfaction . </P> <P> The time constraint refers to the amount of time available to complete a project . The cost constraint refers to the budgeted amount available for the project . 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 . </P> <P> The discipline of project management is about providing the tools and techniques that enable the project team (not just the project manager) to organize their work to meet these constraints . </P>

Discuss the project time and project cost as key variables of successful project implementation
