Awater bottle is ergonomically designed to perfectly fit in the grip of your hand. unfortunately it doesn't fit into most bicycle bottle holders and is a little too big to carry when walking or running. which part of the audience analysis did the designer fail to address?

Bicyclists/runners and athletic people I'm pretty sure. :)

1) environment

2) gender

3) the designer might jump to conclusions and apply stereotypes to the audience.

4) The intended user's prior knowledge of the content at hand

5) understanding

6) context

7) the designers needs to consider how much the audience already knows about the context around which the design is centered

8)  The language spoken by intended users
