The project management triangle forces you to consider the impact of prioritizing one constraint over another. If you prioritize time, you’ll tend to get the project done fast. However, either the scope can’t be nearly as large or you’ll have to shell out more money to try to accomplish your work in less time. If project cost is your top priority, you’ll probably finish under your project budget. But you could end up having to hack scope or miss your desired deadlines, since you’ll either be employing fewer or cheaper people (or both).
