|Concept of 'Ba'
of ba was originally proposed by Japanese philosopher Kitaro Nishida
and further developed by Shimizu. Professor Ikujiro Nonaka adapts
this concept for the purpose of elaborating SECI model of
According to the theory of existentialism, Ba is a context, which harbours meaning. Thus, ba can be considered as a shared space that serves as a foundation for knowledge creation.
Accoding to Nonaka, "Ba" can be thought of as a shared space for emerging relationships. This space can be physical (eg. office, dispersed business space), virtual (e.g., email, teleconference), mental (eg. shared experiences, ideas, ideals) or any combination of them. Ba provides a platform for advancing individual and/or collective knowledge.
There are four types of ba that correspond to the four stages of the SECI model. Each category describes a ba especially suited to each of the four knowledge conversion modes. These ba offer platforms for specific steps in the knowledge spiral process. Each ba supports a particular conversion process and there by each ba speeds up the process of knowledge creation.
The four Ba's proposed by Professor Ikujiro Nonaka are as below:
