Process knowledge is a vital prerequisite for employees to execute organizational processes successfully in the course of their daily work. However, the lack of process knowledge, especially of novice users, and the need for support pose a challenge to employers. Inspired by research on spatial knowledge and navigation, we conceptualize three process knowledge types addressing the needs of employees during their process execution. On the basis of these process knowledge types and decision support and guidance research, we derive three theoretically grounded design principles for process guidance systems to support employees’ process execution. We instantiate the design principles and evaluate the resulting artifacts in a focus group study, a laboratory experiment, and in a field study. The results demonstrate the positive effects of process guidance systems on users’ process knowledge and process execution performance. Our study contributes to research and practice by proposing a new conceptualization of process knowledge and a nascent design theory for process guidance systems that builds on theories of spatial knowledge and navigation, as well as decision support research.

We explored issues related to process knowledge and process execution by conducting a series of expert interviews with open questions. In total eight employees of the case company were interviewed. The expert interviews revealed that the employees experience difficulties in properly executing processes due to a lack of process knowledge. In particular, one of the interviewees requested some “guidance, claiming the system which needs to be used in a particular business process step”.
The systematic literature review serves to identify existing research on decision support and guidance research addressing the three concepts guidance, explanations, and decision aids. Based on the findings, a taxonomy of guidance design features is derived and research gaps discussed.
Derived ten meta-requirements based on existing desicion support and guidance research. The meta-requirements inform three design principles.
We instantiated the design in the form of an artifact for the case company’s procurement department that focuses on structured, document-centric business processes specified by the department.
We performed two focus group workshops with employees of the case company to evaluate the instantiated prototype.
The workshops’ positive results show that the proposed and instantiated functionalities described in the DPs have some validity, which indicates the usefulness of the PGS artifact . Moreover, we found the need for a further meta-requirement.
The literature review is conducted following the guidelines by Webster and Watson (2002) and vom Brocke et al. (2009). According the recommendations of vom Brocke et al. (2009), in a first step the taxonomy by Cooper (1988) is used, who categorizes re-views according to six categories. Table 3 1 summarizes the review intention based on Cooper‘s (1988) categories. Having a clear scope, the literature review was started with the conception of the topic and the definition of search terms.
Guidance design features in information systems are used to help people in decision-making, problem solving, and task execution. Various information systems instantiate guidance design features, which have specifically been researched in the field of decision support systems for decades. However, due to the lack of a common conceptualization, it is difficult to compare the research findings on guidance design features fromdifferent literature streams.
Three main IS research streams form the foundation of guidance and base on the seminal articles of Silver (1991), Gregor and Benbasat (1999), and Todd and Benbasat (1991):
- Decisional guidance (Silver, 1991)
- Explanations (Gregor & Benbasat, 1999)
- Decision aids (Todd and Benbasat, 1991)
The searches were performed in databases being the most important to economics (EBSCSOhost and ProQuest), computer science (ACM Digital Library and IEEE Xplore Digital Library), and information systems (AIS Electronic Library). The databases were selected in order to include the basket of eight and most important conferences in the IS field.

Humans can acquire spatial knowledge from various sources, such as maps, navigation experiences, pictures, and descriptions (Richardson et al., 1999). Spatial knowledge can be divided into two different types: procedural and survey knowledge (Thorndyke & Hayes-Roth, 1982). Thorndyke and Hayes-Roth (1982) define survey knowledge as spatial knowledge about an environment’s topographic properties and as the two-dimensional relationships between locations. This type of spatial knowledge is similar to a map because the relationship between two locations on a map can be identified without additional information about the route (Goldin & Thorndyke, 1982). Users can build up survey knowledge in various ways, such as navigating in a certain environment, which is also referred to as a “primary” experience (Ishikawa & Montello, 2006; Presson & Hazelrigg, 1984). Another possibility to gain survey knowledge is studying a map or an image, which is referred to as a “secondary” experience (Goldin & Thorndyke, 1982; Richardson et al., 1999). Users transform the gained survey knowledge into mental images, which can be used as a physical map to navigate inside a particular environment (Thorndyke & Hayes-Roth, 1982). Researchers have found that gaining survey knowledge through active participation is superior to survey knowledge gained by secondary sources (Presson & Hazelrigg, 1984).
Process knowledge (in general): information about a process, including how it is configured, how it is coordinated, how it is executed, what outputs are desirable, and what impacts it has on the organization (Amaravadi & Lee, 2005).
Process orientation knowledge: information enabling users to locate themselves within the entire process.
Process overview knowledge: information about the various process steps and their sequence within the entire process.
Procedural process knowledge: information on how to execute a specific process step within the entire process.
Process execution effectiveness: the number of times the user correctly executes a process instance (i.e., the process was executed, and the intended outcome / quality was achieved) (Dennis et al., 1996).
Process execution efficiency: the ratio between the correctly executed process instances and the time spent to execute the process instances (Dennis et al., 1996).
