Interviews and Storyboards

We started out by thinking about who the people were that would eventually be using the software we are going to develop. Our main target group are investigators and private detectives. Because of that very specific target group we were not able to conduct our interviews on friends or passerby’s. Our target group of people is extremely hard to get by but we tried to get some of them to give us an interview nonetheless. We contacted a lot of police departments and private investigation firms and asked them for an interview, but unfortunately the timeframe of two weeks was too short of a range for most of them. None of them consented to give us a personal interview but two of them asked us for the questions and agreed to answer them and send us their results. Both of them did not return their results in time. Therefore we could not complete our assignment and weren’t able to draw conclusions and create storyboards based on our findings.

Interview guidelines

With our interviews we wanted to reach two goals: firstly we wanted to find out how our target group does their every-day work and how they would engage in the radically different system that we thought up. Secondly we wanted to find out more about the psychological aspects of such a system. Therefore we broke the interview into two parts. The first part is designed for our target group and is therefore semi-structured and consists of a set of questions. The second part is designed for a psychologist and is unstructured. It only consists of basic areas that we laid our focus on. We found a business psychologist who is an expert in finding out how people interact with products and what their problems and fears are.

Target group interview

Since all of our interviewees are Germans we designed our interview questionnaires in German. We split up the questions of the questionnaire for our target group into several different categories.


Begrüßung. Wie heißen Sie?

Wie alt sind Sie?

Welcher Arbeit gehen Sie nach?

In welchem Betrieb arbeiten Sie?

Welchen Bildungsweg sind Sie bis zu Ihrem Job gegangen?

Wie wird aus technischer Sicht aktuell im Betrieb gearbeitet? Welche elektronischen Geräte werden verwendet (PC, Smartphone, Digitalkamera)?


Welche Personen sind in einer Ermittlung tätig?

Gibt es eine Strukturierung/Hierarchie innerhalb des Betriebs? Hat die Arbeit eine Projektstruktur oder gibt es eine feste Arbeitsverteilung?

Werden regelmäßig/bei Bedarf Meetings einberufen?


Können Sie den Ablauf eines typischen Außeneinsatzes schildern?

Können Sie die Arbeitsaufgaben im Bereich der Büroarbeit beschreiben?

Auf welchem Wege werden neue Erkenntnisse aus den vorliegenden Beweisen gezogen? Wer ist in diesem Prozess vertreten?


Welche Daten werden im Laufe einer Ermittlung gesammelt?

Auf welche Art werden Daten und Beweise zusammengetragen (digital, schriftlich, Beweismittel)?

Existieren Protokolle über Beweisketten (Beweismittel) und Quellen (Aussagen, Erkenntnisse, Beobachtungen)?

Wie werden Daten (IT, Aktenordner) und Beweise gelagert?


Welche Personen haben Zugriff auf die gesammelten Daten?

Wie wird mit außenstehenden Personen verfahren (Datenschutz, z.B. Spurensicherung)? Haben diese Personen auch Zugriff auf die Daten?

Welche Infrastrukturen sind im IT-Bereich vorhanden? Welche Sicherheitsmaßnahmen werden ergriffen?

Abschluss eines Falls

Wann gilt ein Fall als abgeschlossen? Wird ein Abschlussberichtangefertigt? Wenn ja, von wem?

Was passiert mit den gesammelten Daten und Beweisen nach Abschluss eines Falls?


Wie könnte ein solches System in Ihren Alltag integriert werden?

Könnte man mit weiteren Hilfsmittel (Tablets, Smartphones) den Außeneinsatz optimieren oder vereinfachen?

Psychological interview

For the psychological interview we only defined some general areas of interest that we wanted to address during the interview with the business psychologist. These are the areas that we wanted to discuss:

  • Data protection caveats
  • Integration in the everyday work
  • Control concepts (comprehension and acceptance)

With these areas of interest we wanted to find out general flaws in our idea. Usually we would have had to wait for a user to actually engage with an early prototype of our system before we find out any general problems. In order to avoid some general pit falls we wanted to talk to someone who has a lot of experience with great product that failed because they had some basic flaws that detained possible customers from actually using the product.


The psychological interview is the only interview that we were actually able to conduct, we do not have any findings concerning our user group. Therefore we are only able to present the findings concerning the psychological aspects of our project. We structured our findings according to the three areas of interest that we defined in our interview.

Data protection caveats

  • Especially in Germany, people have strong caveats against anything concerning digital data management, therefore some of the investigators might actually not be using such a system out of fear that their data is not protected very well.
  • Investigators and detectives might fear that their superiors spy on them because with such a system it is very easy to comprehend who did what when. They could then, very easily, get in a situation where superiors question the quality of their work and the amount of time it took them to get it done.
  • Especially the administrators of the IT department would be very suspicious and concerned about the data protection. They might even refuse to use such a system.
  • Superiors could fear that such a central system that everyone has access to might enable some of their employees to steal and reveal information relevant to an investigation (e.g. in every major investigation some information is kept back in order to detect copycats).
  • Superiors might fear that they lose the control over investigation data.

Integration in the everyday work

  • Investigators and detectives might fear that such a system complicates their daily work and refuse to use it.
  • Investigators and detectives might have reservations against additional work (“I am not getting paid for this”-mentality).
  • People might refuse to use such a system because they deem it unperformant and rather do it the old-fashioned way.

Control concepts

  • People might fear their own incompetence and are afraid to use such a system because they do not want to do anything wrong and embarrass themselves in front of everyone.
  • Especially concerning the gesture control: people do not want to fidget in front of everyone and ridicule themselves.
  • Investigators and detectives might deem this system to be “just a toy” and therefore refuse to use it.
  • Many of the investigators in service are old, they might refuse to use such a system out of conservatism.


Since we are lacking the results of two interviews we saw ourselves unable to evaluate our findings and therefore decided to wait until all interview result arrive. Also we did not want to create our storyboards until we evaluated all of our interviews because it wouldn’t make any sense to create storyboards and overthrow all of it after we did a thorough evaluation of the interview.
