- Description:
- Strategy Dynamics (Warren, 2008) provides a quantitative, resource-based approach to understanding a firms performance over time. This paper describes a strategy analysis of Starbucks Corporation using Strategy Dynamics. It demonstrates the usefulness of this approach in addressing business performance issues for a real-world company. The strategic architecture, a key artifact of the approach, is a model that captures the interactions of a firms tangible resources, management decisions, and external factors. Starbucks strategic architecture for its retail store business was developed using employee, store, and financial data from Starbucks annual reports and other public information. The strategic architecture and related models were used to explore several issues that can influence Starbucks strategy: customers with less discretionary income, expanding too fast, impact of staff layoffs on the quality of service, getting and maintaining loyal customers, and rivalry with competitors.

- Description:
- Monozukuri (Japanese Manufacturing Style) is said to be one of the specialties of Japan as Ezra F. Vogel pointed out in his "Japan As Number One".ãWith the application of causal loop diagram analysis in systems thinking, this paper tries to reconsider the structure which gives strength and weakness of Monozukuri. The Monozukuri model is developed by unifying various elements which has been conventionally argued in various academic areas. There are three layers of positive causal loops (strength): professional spirits on Monozukuri at an individual level, trust-based style of management as an in-house management-policy at an individual corporate level and trust-based transactions on R&D and parts-supplier-network (Keiretsu) at an inter-corporate level However, these strength loops are shown to be easily turned out to be weak ones. This paper identifies five exogenous variables that turn the strength to the weakness. Trust-based management based on Monozukuri is shown to be superior to the Western-style contract-based management, because the latter brings just a temporary increase in profits, but works as a negatively in the long run. The companies which adopted trust-based style of management have robustness in profit to the technological standardization. Japanese company should continuously improve the structure of strength.

- Description:
- The biofuels production in Colombia is growing in recent years but low investment in refining capacity, crops and difficulties to transport the biofuel to the distribution centers are obstacles to fulfill the demand. In order to analyze these problems a System Dynamics model was constructed for learning about the system behavior and for understanding the response mechanisms to different policies from the production side. An analysis of the current government policies as far as incentives to refining facilities was developed in this paper. According to the model results, alternative or complementarily policies could be appropriated to accelerate the growth in the supply side of biofuels in Colombia.

- Description:
- Group model building is supposed to support the development of shared mental models. This paper illustrates the application of a qualitative method to assess changes in mental models as result of Group Model Building. A quantitative measurement of effectiveness of Group Model Building has been applied by Rouwette (2003). Recently some researchers have been experimenting with a qualitative approach towards measuring effectiveness, which is useful for measuring individual cases and small groups (Dwyer and Stave, 2008, McCardle-Keurentjes, 2008). This paper focuses on the foundation of such a qualitative method from a methodological viewpoint and applies it to a particular case. In this way we aim to introduce a potential standard for evaluating changes in mental models in single cases and to open up the possibility to systematically compare single cases.

- Description:
- Increasing the efficiency of the healthcare system in the United States is an important subject due to rapidly rising costs. Among many propositions to improve the operation of the system, adoption of Electronic Health Records is widely discussed. This study uses a system dynamics methodology to develop a simulation model of the adoption process that will allow for the exploration of policies. This paper presents the development and the preliminary findings of this model.

- Description:
- In todays global competition, companies are obliged to go to market using multiple channels strategy for various reasons. However, channel conflict is inevitable in multi-channel structures causing sharp decreases in the demand of one or more channels. In this article, a system dynamic model was developed to simulate the complex multiple channel structure and various factors that affect the demand and channel conflict. The model aims to simulate the real situation of the supplier decision maker who has to take fast decisions in one of the various variables that he controls to achieve maximum profits and minimum channel conflict. The model was validated using real data of a major consumer electronics supplier in Egypt that has traditional distributors and Hypermarkets as two different channels. Various policies of inventory allocations in each channel and different promotion rates were tested in order to achieve the objective of maximizing supplier profit and minimizing channel conflict. It was found that the policy of allocating the inventory with the equal quantity in both channels with a promotion rate of one promotion per month in the hypermarkets is the optimal policy.

- Description:
- The Australian Capital Territory (ACT) is increasingly threatened by risks to its water security driven by climate change effects, growing population and water-intensive lifestyle. As an inland territory, the ACT has few supply options which are economically and ecologically expensive. Demand management strategies seek to deliver sustainable consumption patterns. Effective communication is an essential part for achieving resilient reductions in consumption by raising public understanding of the problem in order to inform decision making, stimulate public dialogue and ultimately promote behavioural changes. Whereas System Dynamics is a promising approach for learning and communication about water management, its potential for communicating systemic risks to the public has not been fully exploited yet. This ongoing research aims to build a SD Interactive Learning Environment (ILE) to help residents in the ACT to develop a systemic perspective about water management inherent complexity and uncertainty. This paper describes a structured modelling process adopted to build the model through a series of knowledge elicitation cycles, including interviews with stakeholders and electronic workbooks. A key lesson can be taken from our experience through this modelling effort that the modelling process must be flexible and adaptable with several research and real world trade-offs.

- Description:
- Universities (and funding bodies) have been trying to tackle high rates of no-continuation of students in higher education. This paper presents the results of a preliminary investigation into the different factors affecting ânon-continuationâ (or its other side, âretentionâ) of students in higher education institutions. For this purpose, we sketch a systems dynamics (SDy) model and we plan to use data from Universidad de las Americas, Puebla, Mexico and Manchester Metropolitan University, UK, to run the model. We report on relevant literature in the area of the managing retention by assembling a list of retention-related terms; then, relevant models developed to map studentsâ satisfaction, are reviewed. A SDy model that captures the factors affecting the transit of studentsâ from enrolment to graduation is proposed; these factors are synthesised into four sectors as the core of the SDy model: Introduction; Retention; Motivators; and Finance sector. The study is in a developmental stage, we expect to implement the model when data is collected. In this paper, we only report on the literature reviewed and we sketched the SDy model. This investigation, when completed, will provide a tool to understand the factors affecting studentsâ non-continuation and will help education administrators to manage their retention.
