Reflection on the key developments on the organizational knowledge creation theory

Theoretical Background
The organization knowledge creation theory was first developed by Nonaka, (1994) that explained the conversion of tacit and explicit knowledge into organizational knowledge and presented four modes of knowledge conversion that are as follows:

  1. Tacit to tacit
  2. Explicit to explicit
  3. Tacit to explicit
  4. Explicit to tacit
Nonaka, (1994) advocated that “the key to acquiring tacit knowledge is experience” and called the process of creating tacit knowledge through shared experience socialization. In addition to this, he stated that “socialization is connected with theories of organizational culture”.

A review of ISO/IEC/IEEE/DIS 21840 Systems and software engineering – Guidelines for the utilization of ISO/IEC/IEEE 15288 in the context of System of Systems (SoS) engineering

This post reviews ISO/IEC/IEEE/DIS 21840 Systems and software engineering – Guidelines for the utilization of ISO/IEC/IEEE 15288 (NEN-ISO/IEC/IEEE 15288, 2015) in the context of System of Systems (SoS) engineering. A draft of this document is circulated for comments and approval. The document is therefore yet subject to change and might not yet be referred to as an international standard until published as such[1]. While (NEN-ISO/IEC/IEEE 15288, 2015) applies to systems (including constituent systems), this document provides guidance on the application of these processes to SoS. The scope of the (draft) standard is the same as (NEN-ISO/IEC/IEEE 15288, 2015), which establishes a common framework of process descriptions for describing the life cycle of systems created by humans.  It defines a set of processes and associated terminology from an engineering viewpoint.  These processes can be applied at any level in the hierarchy of a system’s structure.  Selected sets of these processes can be applied throughout the life cycle for managing and performing the stages of a system’s life cycle.  This is accomplished through the involvement of all stakeholders, with the ultimate goal of achieving customer satisfaction, hence addresses more than system engineering activities. In addition it explores the similarities and differences between systems and SoS and, by extension, the similarities and differences between engineering of systems and SoS.

Introduction Merishna Ramtahalsing

I am Merishna Ramtahalsing, and as per March the 1st 2019 I commenced with my PhD at the university of Twente in Enschede. Together with my colleagues, I will be working on the SIRA Project (System Integration for Railways Advancement) and will mainly be focusing on the system definition and overview. A proper system definition, a clear vision for the goals and a simple interface for describing the rail transport are key to communication, shared understanding, and collaboration. Therefore, system definition and overview are among principal needs for cooperation. This will include going beyond technical definition of the system and its process, learning from the project management practices, and learning from studies on human behaviour as individuals, groups, or organisations.
