Process models -v- dynamic models : different but related (53)

Process models set out, qualitatively, how parts of the business work : Dynamic models quantify how the system changes over time.

Here’s a challenge – a business needs to hire 35 people for a new team. So it follows a simple process to do that.

Note that the items in this diagram are nearly all verbs, defining what is done to the job applications.

Now here’s a dynamic model of exactly the same process:

In this diagram, every item is a noun, defining – and quantifying – the things themselves (the job applications) on which the processes act.

I humbly submit that the dynamic model is much more useful:

it tells you how much of every item there is, at all times
it tells you how much time the hiring effort will take, and how fast everything will be happening
… so for example, you know how much work the HR folk will be doing on each activity, at all times
it can tell you the impact of changed decisions or uncertainties, like making offers to a larger fraction of applicants or receiving fewer than expected acceptances
… and it still gives a visual description of the process, even if it does not name the activities as the process model does.

So it’s curious, then, that process models are ubiquitous, while dynamic models are still virtually unknown?

Maybe we can change that!
