What-if produces a table of narrative questions and answers suggesting accident scenano.s. consequences, and mitigation. Table 3.3.2-1 shows a typical What-If analysis for the Dock 8. < in the left in the line above the table is indicated the line/vessel that is being analyzed. To the right is the date and page numbers. The first row in the table contains the column headings beginning with i ie what-if question followed by the consequences, safety levels, scenario number and comments. 11C comments column may contain additional descriptive information or actions/ recommendations. 

The results of a What-If/Checklist analysis are documented like the results of a What-lf analysis as a table of accident scenarios, consequences, safety levels, and action items. The results may also include a completed checklist or a narrative. The PrHA team may also document the completion of the checklist to illustrate its completeness. The PSM rule requires detailed... 

A scenario is a particular trace of action occurrences starting from a known initial state. It is written in a stylized narrative form, with explicit naming of the objects involved and the initial state, and it is accompanied by one of the forms of an interaction or sequence diagram. 

Scenarios. Construct scenarios and storyboards of the projected use of the system, starting from a known initial state. Pay particular attention to cases where the system s dealings with one object affect those with another, and cover interleavings of these in a scenario. Create interaction diagrams for the scenarios, combining scenario narrative with the diagrams the interaction diagrams can depict directed arrows or joint action... 

Snapshots are thinking tools rather than true specifications (since they only deal in particular scenarios) but may be used for illustration in the narrative. 

Note A realistic military scenario with EA 3834 was described in detail in Chapter 17 of the main narrative section of this book.)... 

So much for the physical conditions of, and some standard contextual assumptions about the admirable and baffling Etant donnas.. . . Now, as we must presently ask, just what is its imperative but ever so carefully hidden scenario, the one that somehow bristles with cross-references, visual and conceptual And, overall, just what is its full relation to the rest of Duchamp s oeuvre We have just described the physical facts of its appearance, and that is, even on first glance, iconographical. Unfortunately, the only textual material by Duchamp that complements the outer or narrative appearance of this work is its title (even including a subtitle), which becomes, in Duchampian terms, an inscription Etant donnis i° la chute d eau 2° le gaz d eclairage. 

This chapter will describe certain aspects of CTL and will show how the units that make up CORD s ABC series create learning environments in which CTL can fulfill its potential. We will focus particularly on the Water unit (ISBN 1-555-02-837-3), from which the narrative, or scenario, involving Leroy and Veronica was taken. (Every unit in the series has a strong narrative element that enables students to see how the concepts under consideration are used outside the classroom.)... 

As they saw it, that scenario was not only purely speculative, but was based on erroneous assumptions. There was no evidence now or then of a bacterium of any kind that did not produce sufficient amounts of ATP, like the host in that narrative. Nor was there any evidence of a bacterium, like the original theorized symbiont, that produced more ATP than it needed to provide to its host. They proposed instead that the nucleated protist evolved after the acquisition of protomitochondria by an archaebacterial host in an anaerobic context. 

DOCUMENTING THE RESULTS. The what-if analysis produces a tabular listing of narrative-style questions and answers that constitute potential accident scenarios their qualitative consequences and possible risk-reduction methods. Table 4.7 shows the format of a what-if analysis worksheet. Although some what-if analyses are documented in a narrative-style format, a table makes the documentation more organized and easier to use. 

Simplicity - The use of a storyboard is fundamentally simple and strips away technical complexities. Clinical personnel in particular are able to put themselves into the situation and consider how they would act under the circumstances. A story can be recounted by anyone and the listener can comprehend the scenario as the narrative plays out rather than having to construct it from disjointed detail. 

Disaster scenarios. A third factor that has contributed to the view that NT is a controversial area of research is the fact that imaginative and well-informed authors have created narratives of nanodevices that self-replicate and learn. In some visions, ffiose who created such devices to serve their purposes lose control over them, sometimes to great human and/or environmental harm. ... 

Several detailed performance measures were collected, comprising extensive information about the various phases of the scenario corresponding to the defined HFEs. However, for the present paper, audio/video recordings coupled with simulator log data, constituted the fundamental sources for writing partial communication extracts and narratives of crew performance of the HFEs, and for allowing detailed understanding of what the crews did, when they did it, and why. Interdisciplinary teams of operational experts and human factor specialists performed all analyses these constitute the source material for the analysis presented in this paper. Quantitative and qualitative results about the crew performance of the HFEs, the drivers of performance and the observed difficulties will be reported in a Halden Work Report (HWR) and later in a NUREG report, as part of the International Empirical HRA study. 

The experiment was conducted in a laboratory. There were two laptops to present scenarios and questionnaires respectively and two video cameras to record the process. The time was controlled within 45-60 min. Microsoft PowerPoint (PPT) slides were used to guide participants choosing preferred scenarios and representing the chosen ones. Scenarios are represented through descriptors (textual narratives), images (of the context) and videos (only for online webpage scenario) to help participants build a mental model of the usage occasions. Both qualitative methods (i.e., think-aloud protocol (TAP), observations and interviews) and quantitative questionnaires were used to collect dilFerent kinds of information and data.
