Step-by-Step Description of Session No.1

1. Select Top-Level Activity. The user invokes the model, and then
indicates his choice as, perhaps, EDIT (an individual file manipulation
metaphor) or COMPARE SCENARIOS (a more complex activity
metaphor). [An important d~sign d~cision will b~ wh~th~r th~ mod~l
n~~ds to incorporat~ display of output, comparisons of diff~r~nt runs
and oth~r post-proc~ssing, or wh~th~r th~ mod~l should stop at
~x~cuting a run, with comparisons p~1form~d ~xt~rnally.}

2. Browsing Information about Reference Baselines. [For purposes of
this session description, we examine how the model might support a
comparison of two scenarios during an interactive user session.] The
user must specify what to use as the starting point or "reference" for
the comparison. He might be presented with a "dialog box" which
would list the available options, including the original (big-B) Baselin.e
and a number of previously created (little-b) baselines, or reference
scenarios. Since the user may be unfamiliar with those listed, the
dialog box may enable him to select a scenario from the list and get
information, such as the date it was run, the output data saved with the
scenario, the length of the time-series for which the scenario was run,
and a written explanation of the assumptions upon which it was based.

3, Select Reference Baseline. After confirming the identity of the
Planning Commission's standard scenario, the user clicks on "OK."

4. Select Method for Creating New Scenario. The dialog box now
prompts the user to identify the scenario to be compared to the
"reference." His options might include defining a new scenario on the
fly and selecting another from the list of saved scenarios. The user
indicates that he will define a new scenario relative to the current
"reference" scenario.

5. Select a Network-Building Option. A fullcscreen "scenario creation"
window opens, including a scrollable, interactive view of the network
diagram for the reference scenario, a number of building-operation
selectors, and a summary of the changes so far built into the new
scenario. The user selects the building-operation" ADD
DIVERSION."

6.

Specifying Where the Diversion Should Be. The user is prompted to,
"Choose the point of diversion by clicking on one of the highlighted
reach nodes." The user scrolls the diagram to the East River area and
"clicks" on the node at the mouth of Cement Creek.

7.

Drawing the Diversion Arrow. The user is next prompted to, "Click
where the diversion arrow should point." The user clicks in an empty
area on the side of the East River opposite Cement Creek.

8. Naming the Diversion. A diversion arrow appears on the diagram.
The user is prompted to, "Enter diversion name." He types in "Big
Bucks Acres" and hits the enter key.
