model. Qualitative and quantitative research was carried out on the Internet Company to extract
influencing factors. Meanwhile work experience is as reference. The relationship model is established
using the ISM. The adjacency matrix and matrix of direct or indirect relationship between influencing

hierarchy of system is clear. Using hierarchy digraph outlines system schematic diagram and
relationship between various factors. Relationship between system hierarchy models is established. It
provides new ideas for the enterprise to improve the efficiency of product development and optimize
the development process.

Key words: Internet product development, system analysis, interpretive structure modeling;
hierarchical structure, relationship model
