Abstract
Creating value is one of the important missions as knowledge workers in R&D department. Productive knowledge workers require co-worker communication. To comprehend the productivity of R&D development in our company, we analyzed the communication between nineteen employees in a R&D department, as developing an indoor positioning system using BLE beacons. The result of the analysis showed a communication network among the employees was not well-connected, i.e., lack of the meetings between certain teams. To improve the communication, we addressed the implementation of several measures: re-sharing the roadmap of the development with team leaders, randomizing groups for lunch, and so on. As the result of the measures, the communication was improved and some of the employees started changing their workstyles.
