One of the new activities I included in the requirements capture course I wrote for work, and which is presented to both technical and non-technical staff within the Bureau, is an ice-breaking activity looking at why software requirements are difficult.

What is your favourite pen?

Why?

In comparison with a complex piece of business software a pen is a pretty darn simple thing, but even defining the requirements for a pen can be darn difficult.

Here are some suggestions to get you started:

1. •Diameter
   

2. •Weight
   

3. •Balance of weight
   

4. •Friction of ballpoint
   

5. •Viscousity of ink
   

6. •Drying time of ink
   

7. •Suitability for left-handed people
   

8. •Composition of ink (Allergies, ethical or religious opposition to the use of animal products)
   

9. •Colour
   

10. •Comfort when using for long periods of time
