They all work efficiently while the patient is still present, but once she’s gone, they have to do documentation on paper. => that’s where medical informatics comes in

Medical documentation in emergency care lacks structure and is ofter scattered in various places The is no standard on what to document or how First steps toward a solution: A comission of experts formed in 2008 who publish a list of

items to be documentated for each patient in emergecy care There are different modules for every specialty involved For an item to be listed, consensus has to reached in the group The process lacks transparency, which was pointed out by external

experts and scientific reviewers

Unstructured interview with 8 experts, who are members of the working group: 8 experts: „software is unusable for me“. „I don‘t understand the

descriptions used“.

2 experts: „this software is making me do things outside my assigment. That‘s another persons job“.

5 Experts: „I don‘t like the look of the software“, „I can‘t navigate and find the things I want“, „I just don‘t understand it“

3 experts offered specific suggestions on how to change the software to make it more usable

With this seemingly devastating feedback, what do to next? => pivot!

Give the users something they are familiar with to facilitate the change I carefully considered the user‘s feedback when formulating

requirements for the next „round“

Gradually make the change towards a more sophisticated (meta-)model

pivot or persevere?

Create comment

ID: uc_element_02 Name / Title: Create comment on element Primary actor member of the working group (involved user) Other actors • Registered user (interested user) Motivation / Goal in Context:

Point out errors or omissions and initiate or contribute to change or discussion process.

Description: Make one or more comments on a particular item of the data-set. Preconditions • User has to be logged in (authenticated and authorized) Basic Flow / Process:

1. The user looks at the details of a particular item, she is interested in 2. The user identifies an error or omission in the item’s current state 3. The user formulizes a comment pointing to the item’s perceived

shortcomings 4. The user confirms, she wants to publish the comment (though

anonymously)

It‘s possible to create partly model driven applications in Ruby on Rails (with a few minor problems) Despite efforts in requirements engineering, project‘s can be

rejected by aspired users The first approach was „to innovative“ and user‘s could not follow

Taking up the legacy model helped with user acceptance and will hopefully enable the gradual switch to a richer model Some users are more likely to accept a higher level of

complexity. These users should be embraced as „key users“
