Which tool is the best for creating
The answer is remarkably simple.
Sticky pads are the perfect prototyping tool.
Demands for a prototyping tool
Paper sticky pads satisfy all of these requirements.
|Users view a system
as a collection of screens.
A set of A4 size papers, 1 per screen,
precisely fits that perception.
- A user must
understand the prototype with ease.
- A designer should be able to
quickly create and change
- A user should feel
free to comment.
- A prototyping tool must fit in the budget.
Point number two includes another, often overlooked aspect.
A designer's mind is more open for comments if he has not yet spent a lot of time on the design.
What does not work?
- A prototype does not have to look official and in fact, it should not!
The more formal the specification, the bigger the threshold.
- A prototype doesn't have to conform to the mindset of IT staff.
- A prototype does not have to be a full functional specification.
Input for the programmers will follow, later.
- Abstraction puts up barricades.
A screen with xxx and 999 is far less appealing than an example with real values.
- Users think in terms of screens.
To them, information flows from one screen to another.
Diagrams are mostly abracadabra to them.
To them a
logical database design
or dialog flow diagram is just an incomprehensible pulp of boxes and lines.
|A too perfect prototype.|
- A prototype need not resemble the real and final product.
Strangely enough, a
is far from effective.
The user perceives the system as already done and any comments he may have are therefore too late to be of any use.
prototype generates less comments.
IT staff, sharpen the
seize a pair of scissors and a glue-pot.
Get some sticky pads.
And sketch, cut and paste!
