21.4 Taxonomy and Gap Analysis
From the conducted literature review, a taxonomy is derived to classify existing and
future technologies, which aim to contribute to progress for LCSA and the underlying
methods. The aim of the taxonomy is to gain an overview and to assess the current
state of research, industrial applications and the future vision for LC(S)A supporting
technologies.
21.4.1 Approach
Based on the literature review, the taxonomy is developed and a gap analysis
conducted by.
• Abstract keywording: Reading all relevant abstracts and extracting the main
characteristics that describe the research results presented
• Keyword clustering: Grouping the extracted keywords to categories, such as
scope, objective, subjective, type of product or phase of LCSA
• Mapping: the research findings from the literature review are mapped to the
addressed phases of the LCSA and respective challenges (see chap. 2).
• Gap Analysis: At last, the gap analysis is conducted to identify unaddressed
challenges in research and to derive research gaps for technological solutions.
21.4.2 Taxonomy
The resulting taxonomy with nine categories and respective options is shown in
Fig. 21.2. Each technological solution, which aims at enhancing the LCSA execution,
can be located within the proposed taxonomy. For each category, one option is chosen.
Every combination of the different options is possible.
Subsequently all categories are shortly described:
(1) Technology and (2) Characteristics of technology.
In this category, the type of technology, which is presented as a solution, as well as
its automatic and autonomous capabilities can be classified. This category will be
extended with new technologies being developed and applied for LCSA.
(3) Phase of LC(S)A and (4) Aspect of LCSA
This category represents the traditional four phases of the LCSA-process (DIN EN
ISO 2006) and an additional phase, the communication or feedback of the results
to the respective user, which can be a human or an IT-system. In addition, it is
necessary to specify the, which aspect of the LCSA the assessment is focused on.
