It is common knowledgement that small sized firms have the strategic flexibility for sustainable management. The synergies with existing businesses to secure new growth engine is pregnant to rise as a strong going_concern. But many barriers are existing in stages and processes such as collection of tacit knowledge, design, research, development, human resource, financing, etc.. In this study, a factory automation system maker with design capability , during several years, has had a strategic flexibility which the firm has researched and developed the medical device which measures sodium(Na) and potassium(K) in human urine as its new growth engine for sustainable management. The company mentioned above has had a successful case. The successful case has story as following: From the product development through the process of convergence to the requirements of the medical field, research and development has been selected via the item Concurrent access and macro-environment (PEST) analysis. Among the elements necessary technology to medical equipment research and development design a mechanism part to take full advantage of the core competencies of the existing business, production was biosensor linear DNA Aptamer and chemiluminescence protocol improved while using outsourcing from abroad through a fairy tale. Digestion process was being tried. By analyzing the existing Lab on a Chip and avoid patentrelated patents embody the development concept was to develop diagnostic kits addition, diagnostic equipment exterior design were commissioned to proceed with the design and external specialist. It was confirmed that external consultant to reinforce the innovation capacity shortage, strategic alliances with various support organizations and other companies are very important.
