OSTO System Model
The OSTO System Model is based on the OSTO System Theory, which comprehends complex systems and organizations as living systems and maps these by means of the OSTO System Model. The model is cybernetic in nature and is deduced from the theory of closed loops. The basics of this theory have been formulated by David P. Hanna in the 1980s and have been published initially in 1988. The model assumes that several central transformation processes take place on the inside of a complex organization. These are deeply influenced by mutual reactions between the inner life of the organization and the outside. In terms of closed loop theory, the OSTO System Model depicts the essential elements of such a living system in its interconnectedness, dependencies, and reciprocal reactions. Thinking in network structures is, thus, a crucial part of the OSTO System Theory.
The acronym “OSTO” stands for open, sociotechnical, economic aspects of a system. With regard to organizations and economically working companies, the model takes into consideration the openness of systems towards their environments as well as the fact that they are multidimensional, socio-techno-economic structures. Taking into consideration these four aspects, the model displays the complexity of such a system in its numerous dimensions.
Fields of application
The OSTO System Model is a concrete model of the OSTO thought framework. In practice this model is used as a managerial and reflection tool.Looking through the so-called “OSTO glasses” is to facilitate managing the steadily increasing dynamism and complexity of systems such as to find new action strategies by creating distance.
Consequently, for organizational development the method is applied in the field of change management. Companies use the methods in the area of
diagnosis, design and redesign of organizations as well as in project management.
OSTO has developed concepts for education and human resource development in line with the systemic qualification of managers.
The approach is mainly taught at the University of Klagenfurt and at RWTH Aachen University.
It is mainly concentrated in the institute of cybernetics as well as at the chair of information management in mechanical engineering and at the center
for learning and knowledge management. Each year, more than 1000 students acquire knowledge of the OSTO System Theory during a mandatory course
in their studies of mechanical engineering.
O for open system
In the OSTO System approach, organizations are analyzed as open systems. In this context, the attribute “open” refers as well to the spatial and subjectlevel as to the temporal aspect. On the spatial and subject level, not only intended but also unintended exchange with the environment is analyzed.
Systems are hardly ever closed. In consequence of that, bidirectional reciprocal exchange between a system and its environment has to be monitored very
closely. Internal relationships as well as external dependencies of the entire system have to be grasped in order to develop a long-term strategy that
takes consequences into consideration.
S for social system parts
The social side of the system comprises the classical areas of design and process organization, information and decision procedures,division of functions and tasks, as well as the reward and control system. This aspect does, however, also consider the motivation throughout the
company and the relationships among employees and the overall organizational culture. For understanding this part and its influence on the whole
system it is crucial to know that trust plays the most important part in all procedures and processes in which humans are involved.
T for technical system parts
The technical side of the system mainly focuses on the material aspects of companies, such as machines, equipment, internal and external architectureas well as tools and procedures. Additionally, it comprises the conceptualization of technology with regard to centralized and/or decentralized solutions.
Another problem that is tackled within this part of the model is the question as to how technical concepts and tool further fragmentation of work or – if
intended so- in how far they enable integrated wholesome work structures.
O for economic system parts
The economic side of the system describes all aspects which are directly linked to the economic efficiency of the organization, such as revenue trends, productivity development, controlling procedures, remuneration systems, investment and budget planning, fiscal aspects, lead times, cost structure, etc.Formation and development
Complexity, with regard to entrepreneurial action was first described by organizational theorists in the years around 1975. Hence, different managementschools and consultants tried to develop new forms of organizational development since: They intended to understand the internal and external complexities
of companies by developing thought frameworks and creating models.
Up to this point, there were models describing organizations as Tayloristic structures with subdivision of work.
These models are still in use. However, they bear the disadvantage of being incapable of depicting the necessary flexibility. The systemic approach
represents organizations as living organisms which need to flexibly adapt to new conditions. The new aspect of these models is the fact that they consider
the internal and external complexity of an organization and the social psychological phenomena in and around an organization enter the scope of analysis.
The three most important models in this development are the viable system model, the new St. Gallen Management Model
and the OSTO System Model. These models structure the complexity of large organizational structures into
illustrations of one or more dimensions. Another, rather non-famous model, is the “Sensitivity Model” by Frederic Vester.
The OSTO System Model is based on the “Organization Performance Model” which has been developed, tested and published by David P. Hanna in 1988 in his
time as a consultant for Procter & Gamble. Further important participants in this development include Clark/Krone 1972, Krone 1974 and Krug 1992.
Later on, the model has been further developed and systemized for science by Heijo Rieckmann and Klaus Henning as well as for systemic consulting of organizations by Renate Henning.
Description of the model and its variations
Components outside the system environment
System border
Every organization is separated from its environments theoretically by differing borders. Possible forms of such borders are: Physical, temporal, social, or psychological system borders. In order to describe and define a system as accurately as possible it is necessary to determine the borders of a system very carefully. It is a current perception that system borders are partly permeable.
Environment
The environments of a system, i.e. everything outside its borders, have a strong influence on every organization. The model assumes that systems withoutany environment that they interact with cannot exist. A system that is hardly influenced by an environment described as an autarkical system. On the
contrary, a system that is strongly formed by external influences is named a dependent system. In the context of companies an environment can be as
diverse as to be the marketplace, customers, political conditions etc.
Reason for existing
The reason for existing of a system – also to be grasped as the purpose – is the contractual, reciprocal relationship between the system and its environments. It describes which need of the environments is to be satisfied by the core processes of the organization. The Reason for Existing can never be defined unilaterally, which separates it from unilateral, personal interests. In its form it is not to be seen as static, but is also influenced in various ways from the inside and by external factors of the system such that a regular comparison with reality is important. In conjunction with the mission and the goals the Reason for Existing incorporates the overruling “company strategy”.Mission
Next to the Reason for Existing, for every living system a sound mission that is oriented towards the future bears many advantages. The mission questions the long-term sensibility of the Reason for Existing. The internal motivation and identification on the one hand and the acceptance in society on the other hand are maintained through long-term, future oriented thinking. The mission focuses on sensibility with regard to sustainability based on individual, cultural, ethical and further aspects.Ultimate anchor
In applied practice, the Ultimate Anchor plays a minor role. It deeply analysesMission as well as Ultimate Anchor were added to the OSTO System Model by Rieckmann and Henning in the second half of the 1980s since both aspects become increasingly important under the influence of globalization and crisis in society.,
Components within the system
Output
An appropriate depiction of the initial outputs is necessary for the organizational diagnosis. In that regard it is important that “Output” comprises both numerically graspable as well as qualitative aspects. It is just as important to capture the factually or seemingly useless initial results and not only the “official” or “desired” results.Outcome
The term “Outcome” comprises all financial events of an organization: Income from product sales, R&D, etc. It is intended so that the term is slightly broader such that the organization under scrutiny utilizing the model decides itself whether “Outcome” includes prices, sales volume, return on investment, or other aspects.Process version
The OSTO System Model points out that inside an organization the information from the environment, the Reason for Existing and the outputs/outcome are turned into real results through transformational processes. The model provides two explanations for that- Implementation through core processes and transformational processes
- Realization through strategies, design elements, and behavior
