Table 4 Extent of the convergence between IT and a process before developing a new product (example)

Scale point (5-point scales)	Ratio of supporting the entire process (product planning, development plan, development implementation, etc.) for developing a new product through an information system

2	20–40%
1	20% Below

When the full convergence between a product and IT is set as 7 points, and the full convergence between a process and IT is set as 7 points, the reference index is converted into 100 points to make the extent of convergence as an index. And, the convergence index between products and IT and the convergence index between processes and IT are used as a 3 × 3 matrix to derive a convergence index describing the IT convergence level by industry. The methodology to derive the IT convergence index by industry and the framework to derive the convergence index is explained as shown in Figure 4.
