Take the audience into the past: 
  - This is what was happening yesterday.

Bring them to the present:
  - I'm speaking right now. There are some of the challenges, some of the issues we've going on.

Take them into imagined and wonderful future:
  - Maybe if we don't put this right, if we don't learn this project, this is what will happen tomorrow.

You may say:
  - This is what was happening in our industry 5 years ago
  - This is what's happening now
  - This is what's going to happen in the future 5 years from now
