What is the Bass Diffusion Model? The Bass model or Bass diffusion model was developed by Frank Bass. It consists of a simple differential equation that describes the process of how new products get adopted in a population. The model...

There is no single change curve: there are many. And they are all useful to a Project Manager involved in change. So what is the change curve?

Nobody likes resistance, right?

Well, despite this, it's actually a good thing. Let me expla

There’s a simple model of resistance to change that you may be familiar with. It’s...

One of the most insidious problems project managers face is scope creep. Scoping is hard - perhaps the hardest discipline within project management. So knowing how to prevent scope creep will be critical...

Calculus is a branch of mathematics that deals with very small changes. Calculus consists of two main segments—differential calculus and integral calculus. Differential calculus primarily deals with the rate of change of things, while...

The tangential velocity is measured at any point tangent to a rotating wheel. Thus, angular velocity, w, is related to tangential velocity, Vt, through the formula: Vt = wr. Here, r is the radius of the wheel. Tangential velocity is the...

Rockets follow a curved path rather than a straight line because their main objective is to enter Earth's orbit using as little fuel as possible. To get into orbit, a rocket must tilt onto its side and gradually increase the tilt until...

An orbit in space which follows an oval-shaped path. Any small object orbiting a larger one in space will follow an elliptical orbit.
