Dynamic Risk Assessment Systems

DyRiAS-Workplace Violence

DyRiAS-Workplace Violence assesses the behavior of individuals who maintain a direct or indirect connection to the company in question with regard to the risk they present of committing a serious act of workplace violence. The focus lies solely on individuals who have drawn attention to themselves by threatening violence, stalking or communicating violent fantasies.

DyRiAS has been designed for experts of all professions who deal with risk assessment and case management in their respective fields (e.g. members of staff such as trainers, psychologists, psychiatrists, therapists, police officers). These professions are expected to assess the risk of violence presented by an individual of concern – often with no additional forensic training. DyRiAS makes this possible.


What are the benefits of DyRiAS-Workplace Violence?

  • Risk assessment in cases of threats, notorious trouble-making, stalking, and other threatening behavior at the workplace
  • Refined assessments which can differentiate between the possible connections a threatening individual may have to the workplace, e.g. between members of staff, clients or other individuals with some connection to the company
  • Risk assessment according to state-of-the-art scientific research
  • Case-work assisting, structured risk assessment
  • Recognition of dangerous case developments
  • Detailed case report
  • Case summary regarding specific risk factors
  • DyRiAS Risk Assessment as a basis for case management and networking


Overall, DyRiAS-Workplace Violence consists of three modules that differ with regard to the connection the individual of concern maintains to the company:

The module Associate focuses on the risk potential of current or former members of the company’s staff and the question of whether or not an increased risk of serious violence is present.

The module Customer focuses on individuals outside of the company, e.g. customers, clients, suppliers, or other individuals who maintain a connection to the company without being a member of staff.

The module Intimate Partners focuses e.g. on individuals of concern who are currently or were in an intimate relationship with a member of staff and who are threatening or stalking this member of staff or are believed to be a risk in any other way. This module is currently under development.

While the modules Associate and Customer assess the risk presented by both male and female individuals, the module Intimate Partners exclusively assesses the risk of a male individual committing an act of serious violence against his current or former (female) partner.


The system is applied to cases in which a threat, a notification of violence, the communication of violent fantasies or other disturbing behavior has already occurred. It is the aim of risk analysis to correctly assess an individual’s pathway to a targeted act of violence.

The scientific grounding of DyRiAS is based on the review of more than 250 scientific publications on homicides, targeted violence, workplace violence, stalking, intimate partner violence, threat management, and risk assessment. In addition, DyRiAS-Workplace Violence is empirically based on an in-depth analysis of cases of targeted workplace violence from across the world.

Finally, the system was developed with the support of an international advisory board of experts.


DyRiAS provides you with the confidence of working at a state-of-the-art level of risk prognosis and relevant scientific research. A total of 32 questions guide you through the program.

For every question, you are supplied with detailed background information. This is provided by videos of experts who talk about the topic in question, examples of actual cases as well as scientific background information.

You can assess an unlimited number of cases. In addition, you can feed new information into the system at any time and generate a new assessment on this basis. In the timeline analysis you can then discern whether the risk for escalation is increasing or decreasing.This procedure captures the dynamic course of a given case.


At a first level, the risk report presents an overall assessment of the question of whether there is currently a mild, moderate or high risk of serious violence. At a deeper level, it presents a detailed presentation of the actual risk profile, i.e. of the factors that indicate an increased risk in a given case.

As the DyRiAS user is requested to enter a descriptive account of the given case-related situation for each risk factor, a case documentation is always available. DyRiAS allows you to open a given case file at any time and to change the input to the risk factors. In this way, a progress report can be generated that outlines the way in which the risk of violence has developed over time and whether it has increased or decreased.

After information has been entered, a risk report is automatically generated and made available to the user in PDF format. This shows that DyRiAS is neither a check list nor a psychological test, but rather a behavior-based assessment tool. The individual risk factors are not simply added up, but are captured in complex interrelations and are analyzed with the help of statistical methods.
