For each decision, write down the information the user needs to make the decision wisely. One of the marks of a good interface is that everyone feels like they can work the way they want to, that the system does not impose any particular method of solving a problem. This feeling of mastery is often at odds with the users' managers' need to feel in control of the users' work. I'm thinking of a room full of customer service representatives for a major bank or insurance company. The company and its customers will benefit from a certain uniformity in the approach of every user.
Some companies go so far as to script every word the user speaks.
We need to design an interface that satisfies both these desires. The user must feel like the system doesn't impose on their prerogatives. Users with more autonomy will not be under the intense scrutiny described above. Even so, we owe these users a debt, a debt of structure. An interface with no structure, no point of view, gives the user no leverage.
