HI Detlev and all

Detlev, I really appreciate what you've provided and it's a great starting point.  My main feeling upon a first reading is that the wording of this may be too complex for a newer evaluator.  Perhaps we could explain the different scenarious more simply?  I'd like to keep the gist of what you're saying, but just to provide clearer use cases?

Subject: Draft for selecting processes in web applications (addition to Step 3.d)

Hi everyone,

as promised, I have tried to come up with draft (probably within step
3.d) for including complete processes.
Feel free to shred this to pieces...


Step 3.d: Include Complete Processes in the Sample

1. For any critical process identified in Step 2.b: Identify Key
Functionalities of the Website, the *process base page* is included in
the sample. The process base page is the page that acts as launch pad
for other states called up when traversing the process.

2. For processes with branches incl. error handling, record the
*default branch of the process*. The default branch is the simplest
use case, describing the default way through the process. It assumes
that there are no user input errors and no selection of additional
options. For example, in a checkout system, the user would proceed to
checkout, confirm the default payment option, provide all required
payment details correctly, and complete the purchase, without changing
contents of the shopping cart, using a stored user profile, selecting
alternative options for payment or shipping address, providing
erroneous input, and so forth.

3. For processes that consequently call up or generate further pages
(new URIs), add these *derived process pages* to the page sample,
directly where possible or by specifying the actions on the base page
of the process that led to it (e.g., "fill out form correctly and
press "Submit"). The page description should indicate that this
derived page is part of the same process as the first page, for
example, through consistent numbering.

4. For each page of the process, the *page process record* should at
least describe as list all steps / user interactions that lead to
consequent process states on the same page. Optionally, it can include
screen shots for these states. Whenever a process calls up a new URI,
consequent states should enter the page process record of that derived
process page / URI in the sample.

5. The page process record need only specify additional states to be
evaluated, i.e., all elements that are added, modified or made visible
on top of the base page.

6. For processes with branches that are commonly used or entered and
are critical for the successful completion of the process, register
*critical alternative branches* of the same process. Branches may
terminate where they re-enter the default branch of the process, or be
covered until their completion. For example, adding a new shipping
address will be registered as a critical alternative branch that leads
back to the default branch of the process.

Finally, two bits that might be added later in Step 4 "Audit the
selected sample" to help operationalize checking processes in the
still rather vague Step 4.a: Check for the Broadest Variety of Use

* Those parts of the base page that remain unchanged need not be
evaluated again when evaluating a particular page state.

* When evaluating elements in alternative branches that are found to
be substantially the same as those already covered in the evaluation
of another branch, the evaluation may simply record pass/fail and
clearly refer to the comment made at the other location.
