4.1. The Analysis of the AIA (Acquisition–Importance Analysis) Approach
The axes on the competency position map include the AI and the II. The AI evaluates the acquisition level from the Med-Tech business viewpoint, while the II shows the importance level for the Med-Tech business. As shown in
Figure 2, the
x-axis is the Acquisition Dimension (AD), and the
y-axis is the Importance Dimension (ID). In this study, the digital transformation strategies for the Med-Tech industry include five aspects, PC, OM, CR, RS, and ME.
The position map of the digital transformation strategies for the Med-Tech industry is divided into four quadrants. The first quadrant (H, H) represents a high AD and high II (importance index). The aspects in the first quadrant mean that the Med-Tech businesses consider the segment as an acquisition and deserving of importance. Thus, the aspects in the first quadrant are called “easy acquisition and high importance (H, H)”. The second quadrant (L, H) represents a low AI but a high II (importance index). The aspect in the second quadrant means that the Med-Tech businesses do not consider the segment as a hard acquisition, but they still think these aspects/criteria are important and critical. Thus, the segment in the second quadrant is called “hard acquisition and high importance (L, H)”. The third quadrant (L, L) represents a low AI and a low II. The aspects in the third quadrant mean that the Med-Tech businesses consider the segment as a hard acquisition, and they also do not think their aspects/criteria are important. The segment in the third quadrant is called “hard acquisition and low importance (L, L)”. Last, the fourth quadrant (H, L) represents a high AD and low ID. The aspects in the fourth quadrant mean that, although the Med-Tech businesses consider the segment is an easy acquisition, they do not believe these aspects/criteria are important and critical. Consequently, the segment in the fourth quadrant is called “easy acquisition and low importance (H, L)”.
The aspect of RS and PC was located in the second quadrant (L, H), indicating that the aspect of RS and PC were characterized by low AI and high II. Hence, the Med-Tech businesses consider that the aspect of RS and PC are hard acquisitions and of high importance for the digital transformation. Although the Med-Tech businesses do not consider the acquisition as easy, the RS aspect and PC aspect, but the aspects of RS and PC are the critical and important aspects, the Med-Tech businesses should consider developing the professional competence and establish the regulatory system through in-house development. Therefore, the development strategy of in-house development should be applied in the second quadrant. The aspects of CR and ME were located in the third quadrant (L, L), indicating that the aspects of CR and ME were characterized by a low AI and a low II. Hence, the Med-Tech businesses consider that the aspects of CR and ME are hard acquisition and of low importance for the digital transformation. Although the Med-Tech enterprises consider critical resources and market expansion ability are hard to acquire, but the CR aspect and ME aspect still do not involve the critical and important aspects, and the Med-Tech enterprises can maintain the current status. Therefore, the development strategy of maintaining the status quo can be applied in the third quadrant.
The OM aspect located in the fourth quadrant (H, L), indicating that the aspect of OM was characterized by high AI and low II. Hence, the Med-Tech enterprises consider that the OM aspect is an easy acquisition but of low importance for the digital transformation. Although the Med-Tech enterprises consider the ability and resource of operation management as easy to acquire, the OM aspect is not a critical and important aspect; the Med-Tech enterprises can form alliances with other support chain partners. Therefore, the development strategy of strategic alliance can be applied in the fourth quadrant, as shown in
Table 3 and
Figure 3.
4.2. The NRM Analysis Based on the DEMATEL Technique
The DEMATEL technique was adopted to construct the structure of the network relationships map (NRM) for the digital transformation of the Med-Tech industry. When users are making decisions about the digital transformation of the Med-Tech industry, there are many criteria they may consider. The most common problem they face is how these aspects impact each other. Therefore, before making development decisions, it is necessary to know the essential aspects and then make useful improvements to enhance the overall capability of digital transformation. When a decision-maker needs to develop many aspects, the best way to handle this is to determine the aspects that most impact others and improve them.
Recent studies have used the DEMATEL techniques for solving complex problems, such as the analysis of user interface [
47], failure sorting evaluation system [
48], the innovation policy portfolios of Taiwan’s SIP Mall industry [
49], the evaluation system of e-learning programs [
50], the evaluation system of knowledge management strategy [
51], the value-created systems of science (technology) parks [
20], and the key success factors of block-chain for sustainable supply chain [
52], the selection of R&D projects for energy sector based on the fuzzy based approach [
53]. This study divides DEMATEL into five steps: (1) Calculate the original average matrix, (2) calculate the direct influence matrix, (3) calculate the indirect influence matrix, (4) calculate the full influence matrix, and (5) analyze the NRM (network relation map).
- (1)
Calculate the original average matrix
Respondents were asked to indicate the influence that they believed each aspect exerts on each of the others according to a scoring scale ranging from 0 to 4. “0” means no influence, whereas “4” means “extreme influence” between aspect/criterion. “1”, “2”, and “3” mean “low influence”, “medium influence” and “high influence” respectively [
54]. As shown in
Table 4, the influence that “PC” has on “CR” is 2.688, which means “medium influence.” The influence that “RS” has on “PC” is 2.713, which also means “medium influence” as shown in
Table 4.
- (2)
Calculate direct influence matrix
From
Table 4, we processed the “Original average influence matrix” (
A) by Equations (1) and (2) and got the “Direct influence matrix” (
D). As shown in
Table 4, the diagonal items of
D are all 0, and the sum of a row is at most 1. Then we got
Table 5 by adding up rows and columns. In
Table 6, the sum of row and column for “Operation management (OM)” is 1.980, which is the most important influence aspect. On the other hand, the sum of row and column for “Regulatory system (RS)” is 1.884, which is the least essential influence aspect.

And , where , when or , and at least one or equals one, but not all. So, we can guarantee .
- (3)
Calculate indirect influence matrix
The indirect influence matrix can derive from Equation (3), as shown in
Table 7.
- (4)
Calculate the full influence matrix
The full influence matrix
T can be derived from Equation (4) or (5);
Table 8 is the calculated full influence matrix. As shown in
Table 8, the full influence matrix [
11] consists of multiple elements, as indicated in Equation (6). The sum vector of row value is [
53], and the sum vector of column value is [
53]; the sum vector of row value plus column value is {
di + ri}, which describes the full influence of matrix
T. As the sum of row value plus column value {
di + ri} is higher, the correlation of the dimension or criterion is stronger. The sum of row value minus column value is {
di − ri}, which describes the net influence relationship. If
di − ri > 0, it means the degree of influencing others is stronger than the degree of being influenced. As shown in
Table 9, the OM has the highest degree of full influence (
= 70.930). The aspects of CR and RS are the highest net influence (
= 1.036). The order of other net influences is listed as follows: OM (
= −0.084), PC (
= −0.408), and last, the ME (
= −1.580).
- (5)
Analyze the NRM (Network relation map)
Experts were invited to discuss the relationships and influence levels of criteria under the same aspects/criteria defined in
Table 1 and to score the involvement and influence among criteria based on the DEMATEL technique. Aspects/criteria are divided into different types, so the experts could answer the questionnaire in areas/fields with which they were familiar. The net full influence matrix,
, is determined by Equation (9).
The diagonal items of the matrix are all 0. In other words, the matrix contains a strictly upper triangular matrix and a strictly lower triangular matrix. Moreover, while values of the strictly upper and strictly lower triangular matrix are the same, their symbols are opposite. This property helps us; we only have to choose one of the strictly triangular matrices.
Table 8 shows the full influence matrix, and Equation (9) can produce the net influence matrix shown in
Table 10. Using the values of (
) and (
) in
Table 9 as X and Y values, respectively, the NRM (Network relation map) approach can be drawn as shown in
Figure 4 [
55].
Figure 4 shows that RS (regulatory system) and CR (critical resources) aspects are the primary aspect with net influence, while ME (market expansion) aspect is the primary aspect being influenced. The OM (operation management) aspect is the aspect with the highest full influence, while the RS (regulatory system) is the one with the smallest full influence aspect.
4.4. Discussion
The ranking of the AI is
and the ranking of the II is
based on the AIA approach as illustrated in
Table 12. There are eight development paths (RS→ME; RS→PC→ME; RS→OM→ME; RS→CR→ME; RS→OM→PC→ME; RS→CR→PC→ME; RS→CR→OM→ME; RS→CR→OM→PC→ME) in the evaluation system, based on the NRM approach. Further, we can improve the disadvantage aspects/criteria through the advantage aspects/criteria based on the aspects/criteria rank of AI and II. The ranking of the AI is
, and the ME aspect can be improved through RS aspect based on the first development path (RS[2]→ME[3]). The PC aspect can be improved through the aspect of RS based on the second development path (RS[2]→PC[5]→ME[4]), and then the ME can be improved by OM aspect based on the third development path (RS[2]→OM[1]→ME[4]) as illustrated in
Table 12. The ME aspect can be improved through the CR based on the fourth development path (RS[2]→CR[2]→ME[4]). The PC aspect can be improved through the OM aspect based on the fifth development path (RS[2]→OM[1]→PC[5]→ME[4]). The PC aspect can be improved through the CR, and the CR aspect can be improved through RS aspect based on the sixth development path (RS[2]→CR[2]→PC[5]→ME[4]). The ME aspect can be improved through the OM, based on the seventh development path (RS[2]→CR[2]→OM[1]→ME[4]). The PC aspect can be improved through the OM, based on the eighth development path (RS[2]→CR[2]→OM[1]→PC[5]→ME[4]), as illustrated in
Table 12.
The ranking of the II (importance index) is
, and the aspect of ME aspect can be improved by the RS aspect, based on the first development path (RS[1]→ME[3]) and the aspect of ME can be improved through the PC and PC can be improved by the RS aspect based on the second development path (RS[1]→PC[2]→ME[3]), as illustrated in
Table 12. The aspect of OM can be improved by the RS aspect based on the third development path (RS[1]→OM[5]→ME[3]). In addition, the aspect of CR can be improved by the RS aspect based on the fourth development path (RS[1]→CR[4]→ME[3]), as illustrated in
Table 12.
The aspect of OM can be improved by the RS aspect and ME (market expansion) aspect can be improved by the PC aspect, based on the fifth development path (
RS[1]→
OM[5]→
PC[2]→
ME[3]), as illustrated in
Table 12. Further, the aspect of CR can be improved by the RS aspect and ME aspect can be improved by the PC, based on the sixth development path (
RS[1]→
CR[4]→
PC[2]→
ME[3]), as illustrated in
Table 12. The aspect of CR (critical resources) can be improved by the RS based on the seventh development path (RS[1]→CR[4]→OM[5]→ME[3]), as illustrated in
Table 12. In addition, the aspect of CR can be improved by the aspect of RS and ME aspect can be improved by the PC, based on the eighth development path (RS[1]→CR[4]→OM[5]→PC[2]→ME[3]), as illustrated in
Table 12.
Therefore, the AIA-NRM approach integrates the AI development paths and the II development paths; the best-suited development paths are illustrated in
Table 12. Because the AI development paths and II development paths are the same in the empirical result, the best-suited development paths include the eight development paths (RS→ME; RS→PC→ME; RS→OM→ME; RS→CR→ME; RS→OM→PC→ME; RS→CR→PC→ME; RS→CR→OM→ME; RS→CR→OM→PC→ME), as illustrated in
Table 12.
