2. Pick a choice that the office made in developing their assessment model. What are the trade-offs of this choice versus other options they could have taken? How might this choice impact different stakeholders?

3. Identify one type of bias that you think would impact the property assessment model. How might you evaluate this bias? What steps could you take to mitigate it?
