FAQs

What are successful projects?

Successful projects are those that are completed on time, within budget, and according to the established scope outlined in the project documents. To fully grasp what defines a successful project, it’s important to define the specific meanings of cost, scope, and time beyond their general interpretations.

What is the biggest science project ever?

The biggest science project ever is the famous Pitch-Drop experiment, which holds the Guinness World Record for being the longest-running experiment in history. This experiment is still ongoing today. Essentially, pitch is a viscoelastic polymer derived from plants, petroleum, or coal tar.
