Abstract
Automation of industrial processes is a necessary step towards the Industry 4.0 vision. There are several justification techniques available that can help to improve chances for success in automation projects. A literature review on justification techniques and their usefulness is carried out. Based on the review, a set of criteria for evaluating justification techniques are developed. A case study is carried out in a company with an ongoing manufacturing system development project that includes decisions regarding processes and technologies that require a systematic evaluation and justification. Two justification techniques were selected and tested in the development project. The tests show that both justification techniques provide good support for the technology acquisition process. Strengths and weaknesses of the tested techniques are highlighted. The study suggests that the choice of method should depend on the type of acquisition process of a company, especially with respect to technology strategy, competences, and supplier relations.
