“…Step 1 -Systematic literature review for the identification of relevant information The systematic literature review is conducted to identify relevant information and provide it as input data for the LDA in the next step. It is conducted as described in Borrego et al (2014) and adapted to the field of engineering design by Riesener et al (2019) and Petersen (2017). A systematic literature review attempts to reduce subjectivity through the totality of the works and the associated perspectives (Borrego et al, 2014).…”

“…It is created to support the decision process within the engineering change process. The three possible outcomes of an ECR are: Approval, dismissal or rework (Riesener et al, 2019). The purpose of an ECR is summarised and defined as: "The engineering change request (ECR) is a request for a technical change in the state of a product model that has already been released for further development or production."…”

“…Even though there are many approaches that develop description models of ECR, all description models were developed with a specific purpose and therefore focus on a few aspects, instead of conducting a systematic approach to identify characteristics of ECs and ECRs holistically. In addition, Riesener et al (2019) identified the need for a description model in the process of evaluating ECRs. The theory deficit concerning description models can be summarised as follows: A holistic description model considering all aspects of ECRs is not present.…”

Complex products and shorter development cycles lead to an increasing number of engineering changes. In order to be able to process these changes more effectively and efficiently, this paper develops a description model as a first step towards a data driven approach of processing engineering change requests. The description model is systematically derived from literature using text mining and natural language processing techniques. An example of the application is given by an automated classification based on similarity calculations between new and historic engineering change requests.
