Figure 2-20 A sequence of status messages traces the steps of an operation
Progress Indicator 2
The progress indicator, if present in a status slip, can take different forms. It
can be a simple “barber pole” gauge, which animates a set of diagonal stripes
while the operation progresses but does not indicate how much of the
operation has been completed. Alternatively, if it’s possible to quantify the
progress of the operation that’s underway, then a status slip should include a
progress gauge that indicates relative completeness of the current operation
as a shaded portion of the entire gauge. Figure 2-21 shows two examples of
progress gauges.
