WDB Group Advantage

WDB’s equation for success and rapid growth : Simplify, Standardize, Systemize and Run

Simplify and Standardize:

WDB created a “Standardized Business Procedure” by simplifying tasks with highly skilled workers who follow a detailed work flow. Ultimately, WDB is capable of providing high quality, efficient services at a low cost. Due to this effective business procedure, WDB has been about to expand dramatically.


In 1985, WDB began offering HR clerical services. In 1997, WDB expanded to offer HR services for Research and Development. These HR services for R&D positions were able to be handled by staff without any previous R&D background or knowledge. WDB made it possible for inexperienced workers who had just graduated college or part-timers without the necessary skills or experience to learn and adapt quickly due to the systematic approach and methods developed. This approach allows us to work with 98% of the pharmaceutical companies in Japan and to be #1 in R&D HR services in Japan. In 2008, WDB introduced temporary staffing services to Global Pharmaceutical Company to assist on Phamacovigilance work. We continue to provide ongoing services to Global Pharmaceutical today.


Our standardized business procedure allows us to run efficiently, to train inexperienced workers effectively and offer considerable savings to our clients. Our first successful challenge was HR for R&D positions. Our second successful challenge was CRO services in Japan. And now, our third challenge is to offer CRO services in the USA.
