Optimism

We are Optimistic - we think we can create software that will

help users / make their lives better / make us money (?-yuck!).

We think we will bash every bug, satisfy every requirement, code

elegant and beautiful code.

This Optimism can be our downfall!

Can you Answer...

1. You are suffering from the ‘Too–Little–Time’ constraint and

need to get a formative evaluation with 20 people

(employees of the factory commissioning your new

production line software) underway very quickly. At this

stage you only need qualitative results – how would you go

about getting this information in the fastest time possible,

and why would you be cautious?

2. What are commissioning constraints?

3. What is real world work limited by?

4. Why is optimism often a bad mindset to have when it comes

to planning UX work?

5. Describe the ‘Second System Effect’ ?
