Program planning interactive model

Hello,
This week i discovered that out of all the assumptions( seven altogether) mentioned in the book on Program planning by R.S Caffarella, on which interactive model is built, the most important one to me is attending to preplanning and last minute changes.This is necessary because unforseen situation or circumstances may arise and is beyound our control.

Situations like this may cause a little bit of  delay in the programs for instance, a workshop that I suppose to attend today was cancelled because it was very slippery on the highway. Weather condition often do not permit  workshop to take place, therefore it is very important in the planning process to put into consideration weather condition, delay from the presenter and learners not showing up for the workshop.

The planning process stage is the most significant level.

Thanks for reading.
