In extant studies regarding value stream mapping (VSM) and cross-functional integration in Western journals, there is a deviation from the essence of lean production and flow management, which aim at overall optimization by focusing on the flow of the entire value chain as well as material and information flow, and empirical studies based on the actual state of material and information flow have not been sufficiently conducted. To proceed with the overall optimization of the material and information flow in the supply and value chain—with progress in globalization and digitalization as seen in recent Japanese manufacturing companies—it is necessary to return to basics to grasp the “actual state of the flow” by focusing on the entire material and information flow and to conduct empirical studies on factors contributing to these flows.

Studies of the value stream mapping (VSM) in Western journals report that leveraging VSM as a lean tool results in performance improvements. However, in these articles, VSM is functioning as a tool for partial optimization, attempting to identify and resolve bottlenecks in individual functions and divisions, primarily in production activities. For that reason, the greater the degree to which VSM underpins success, the more it deviates from the original essence of lean production and flow management, promoting overall optimization by focusing on the flows across the value chain, and potentially leading to poorer performance in the overall value flows up to the customer.

Papers on operations management in major journals have studied (1) relationships between the level of alignment in business and manufacturing strategies, practice realization, and performance; (2) the role of plants in global production networks; and (3) the reconciling of business and manufacturing strategies by operational executives. However, while these studies have positioned the role of plants as a strategic weapon in firms, their perspective is that the role of plants is imparted by headquarters or business units. Actually, the phenomenon which Japanese domestic plants have continued to work on various issues in an advanced manner from a global view went beyond this scope. There is a need for exploratory research from the perspective of plants as to the relationship between the role of plants and the strategic behavior of factory managers in continuing to grow while trying to survive in challenging environments and organizational capabilities built in plants.

Since the 1990s, research has been done on lean production systems with progressive development of a scale for measuring characteristic leanness in efficient production organizations. For example, Shah and Ward (2003, 2007) originated from the HPM and IMSS surveys become as the de facto standard. However, the explanations of these studies were not necessarily convincing. In contrast, in the IMVP survey, site visits were made to automakers’ development and production genba or sites in each country surveyed, in addition to the use of questionnaires. However, in actuality, a comparison of multiple Japanese automakers showed differences in methods and means for achieving just-in-time production in organizations, even at the genba that would be believed to score high on a leanness scale, such as JIT production. It is difficult to detect and measure these differences through large-scale cross-industry questionnaire surveys alone, and there is a possibility that this difficulty manifests in the weak explanatory power of the lean studies. Approaches to explaining differences in performance using “leanness scale” are based on a lean hypothesis where there is a best practice lean situation transcending nations and industries, yet its low explanatory power creates suspicion with regard to the validity of this hypothesis.

This study employs data collected from a questionnaire survey of 97 business operations (factories) in Japan's electric and electronics industry to measure gemba-level and market-level competitiveness based on the framework of Fujimoto (2003). In addition, the employment situations within these sites were surveyed. The results of these surveys revealed that, as strengths of the electric industry gemba in Japan, 1) these gemba are superior in all metrics of competitiveness except for manufacturing cost, relative to overseas sites in the same companies; and 2) the high level of responsiveness to customers is the major source of market-level competitiveness. Nevertheless, the primary issue faced by these gemba is the skewed age composition of the full-time employees. There are few workers to carry forward necessary skills into future, and the labor costs of the veteran workers are increasing. Japan's manufacturing gemba must develop manufacturing competencies and improve design and development capabilities, in addition to nurturing younger personnel, to gain and sustain competitive advantage.

Beginning in the latter half of the 1990s through the early 2000s, research on dynamic capability (DC) emerged. Teece, Pisano, and Shuen (1997) were famous for being quoted even while only having a working paper, which was subsequently published. They were followed by Eisenhardt and Martin (2000). Then, researchers such as Zollo and Winter (2002) studied routines and organizational learning with a focus on the keyword “capability.” These three influential papers cited the following concepts as elements that comprise DC: 1) the level of environmental change; 2) organizational processes or routines; 3) resource configuration; 4) the role of managers (for example, decision making with regard to resource investment); and 5) learning mechanisms. Later, many researchers adopted a resource-based view (RBV) and presented their studies as incorporating DC if they contained the keywords “change,” “competitive advantage,” or “capability” even though they were merely descriptions of static resource states and discussions of their changes. By casually labeling research on R&D, acquisitions, or alliances as DC theory, these later studies a) caused ambiguity and confusion with regard to what “dynamic” means and b) lost sight of the essence of DC theory with various solutions concerning whether the concept can be explained with the stable characteristic of capability.
