Changing working habits is difficult

I've taught thousands of modellers from many of the world's top companies over the years. And what I've seen is this: in all but a handful of dedicated modelling shops, it's hard for companies to achieve standardisation across a team.

People have their own preferences. And these have often been built up over years of practice. It's challenging and painful for them to change. And they may not be convinced that what they are switching to is better. And indeed it may not be.

As software developer Paul Graham said:

"Programming languages are not merely technologies, but habits of mind as well, and nothing changes slower."

If you already have modelling experience, you may find that the approaches that I outline in this book feel artificial and "not what you'd normally do".

This is normal.

All I ask is that you come this work with an open mind, and a healthy dose of skepticism.  It may be that your own approach works just is well. In which case, keep using it.

However be aware when skepticism is just resistance to change.
