                                         POLICY HANDBOOKS.  The last type of qualitative document we consider is the policy handbook.
                                         Although these documents typically cover broad areas of employee and corporate behavior, a
                                         systems analyst can be primarily concerned with those that address policies about computer
                                         services, use, access, security, and charges. Examining policies allows a systems analyst to gain
                                         awareness of the values, attitudes, and beliefs guiding the corporation.


                                         Observing a Decision Maker’s Behavior
                                         Observing decision makers, their physical environment, and their interaction with their physi-
                                         cal, ergonomic environment is an important unobtrusive method for a systems analyst. Through
                                         observing activities of decision makers, an analyst seeks to gain insight about what is actually
                                         done, not just what is documented or explained. In addition, through observation of the decision
                                         maker, an analyst attempts to see firsthand the relationships that exist between decision makers
                                         and other organizational members. Observation of decision makers’ interactions with technolo-
                                         gies can also reveal important clues regarding HCI concerns, such as how well the system fits
                                         with the user.

                                         Observing a Typical Manager’s Decision-Making Activities
                                         Managers’ workdays have been described as a series of interruptions punctuated by short bursts
                                         of work. In other words, pinning down what a manager “does” is a slippery proposition, even
                                         under the best of circumstances. A systems analyst can grasp how managers characterize their
                                         work by using interactive interviews and questionnaires. Observation, however, allows the ana-
                                         lyst to see firsthand how managers gather, process, share, and use information and technology to
                                         get work done.
                                             Although it is possible to describe and document how managers make decisions using boxes
                                         and arrows, we are primarily describing humans and their activities. Therefore, we suggest that
                                         systems analysts use a more humanistic approach to describe what managers do. This method
                                         is called the analyst’s playscript. With this technique, the “actor” is the decision maker who is
                                         observed “acting” or making decisions. When you set up a playscript, you list the actor in the
                                         left-hand column and all his or her actions in the right-hand column, as shown in Figure 5.7. All
                                         activities are recorded with action verbs, so that a decision maker would be described as “talking,”
                                         “sampling,” “corresponding,” and “deciding.”
                                             Using a playscript is an organized and systematic approach that demands the analyst be able
                                         to understand and articulate the action taken by each observed decision maker. This approach
                                         eventually assists the systems analyst in determining what information is required for major
                                         or frequent decisions made by the observed people. For instance, from the quality assurance
                                         manager example in the playscript, it is clear that even though this decision maker is on the
                                         middle management level, he or she requires a fair amount of external information to perform the
                                         required activities of this specific job.


                                         Observing the Physical Environment
                                         Observing the activities of decision makers is just one way to assess their information require-
                                         ments. Observing the physical environment where decision makers work also reveals much
                                         about their human information requirements. Most often, such observing means systematically
                                         examining the offices of decision makers because offices constitute their primary workplace.
                                         Decision makers influence, and are in turn influenced by, their physical environments and by
                                         their interactions with the technology that takes place there. Many HCI concerns can be identi-
                                         fied through structured observation and confirmed with other techniques, such as interviews or
                                         questionnaires.

                                         Structured Observation of the Environment (STROBE)
                                         Film critics sometimes use a structured form of criticism called mise-en-scène analysis to sys-
                                         tematically assess what is in a single shot of the film. They look at editing, camera angle, set
                                         decor, and the actors and their costumes to find out how they are shaping the meaning of the film
                                         as intended by the director. Sometimes the film’s mise-en-scène will contradict what is said in
