"the art of project management. A mixture of administration, planning, experience, analysis, people-skills, political wrangling, leadership and a little bit of luck"

By Rod Hutchings MAppSc MAIPM MACS RegPM(MPD)

The triple constraint involves making tradeoffs between scope, time and cost for a project.  It is inevitable in a project life cycle that there will be changes to the scope, time or cost of the project. However where most projects fail is that when one of the areas changes and appropriate adjustments are not made to the other areas. 

For example, if a deadline is moved up, what actions are needed with regards to cost or scope to ensure the deadline is met without compromising the quality of the product.

Another way of looking at the Fourth Constraint could be that the quality aspect could be included in the scope goal.

Quality is actually a forth constraint to the project. I.e. we need to make a pragmatic decision on what level of quality the project needs to achieve. As we get closer to 100% on quality the costs and time will grow exponentially.

Of course it is much more difficult to visualise four dimensions :)
