Before we start today's lesson, I have a few items of little housekeeping to get out of the way first:
  • Your Starbucks assessment (which you're doing in pairs) is due tomorrow. It is due at 9am, meaning that as you walk in to class in period 1 you should hand it in and then we will get started learning about the next part of Decision Support Systems. If it is not printed and submitted right at the beginning of the lesson, it will receive the 10% penalty! So make sure it's on time. 
  • Morning class on Wednesday is cancelled. You've all worked really hard this term, so I'm giving you a morning off. 
  • On Thursday afternoon we have our last class for the term. I had originally thought we would not have class due to the Cross Country Carnival, but I found out that the cross country will occupy the first 3 period of the day. It's a double period, so my plan is to cover a little bit of content... and then use the leftover time to celebrate the fact that you are halfway through the HSC course (hooray)! So please make sure you bring along some thing to, ummm, contribute to the festivities. 8-)
Alright then, let's begin our lesson!
  1. Propose reasons for why a computer-based system might have significant difficulties providing decision support for a human. 

  2. Explain, with an example, how vague problem data can lead to inaccurate or even harmful decision support. (Example)

  3. For each of the following: (a) describe the method, (b) provide two examples of where this method would be suitable and (c) provide one example of where this method would be unsuitable.
    • optimising
    • satisficing
    • heuristics
