Toolbox

Examples: Context:  The artifact supports the creation of other artifacts, as in a WYSIWYG Editor.

Problem:  How should the artifact present the actions that the user may take?

Forces:

Solution:  Keep tools together, put them physically close to the user's working surface, and make sure they are distinct from other actions that the user may take.  If the tools can be represented well as icons and not words, use icons; they usually represent visual objects or modes anyway.  Let the users position the tools where they want (Personal Object Space).

Organize the tools according to how they are used, so that the most common ones are the most prominent (for instance), and localize them by task, so that the user doesn't have to jump around a lot as they're performing common complex tasks. Users can generally deal with seeing large sets of them -- no one minds a well-organized 20-item palette, and exposing them all means the user doesn't have to spend effort getting to them -- but break them up by function if necessary ( Groups of Related Things).

Allow the user to introduce other tools from outside the artifact, if possible. Put the foreign tools with the others, so that the user doesn't have to deal with an artificial separation between "ours" and "theirs."

Resulting Context:  In a software artifact, use Short Description or Pointer Shows Affordance if there's any doubt that the user will recognize the tools as they are statically represented.  Try not to depend upon them, though -- it's easy to get lazy and use poor icons, knowing that a user can just use the tooltip for something they don't understand.  The problem, of course, is that a user then has to move the mouse over every single tool to figure out what they all are.  This is far from ideal.

Notes:  The first force in this pattern is just my intuition, based on empirical evidence.  I freely admit that don't have much of a basis for it.  Unfortunately, the pattern's distinctiveness hinges on it, so any help on this front would be welcome...
