Product named MBF is being used in this research as it represents the characteristics of discounted products in the company. Using actual sale, sale forecast, inventory product 2013-2014 datas, and system dynamics approach, we intend to show that price discount policy causes fluctuation of sales and inventory level which in turn affect the company's profits. Research concludes that the coordination between marketing and logistics company in order to respond the price discount policy provides a +/- 3,5% higher profit for the company along with 7,69% reduction in transportation cost and 20% stock out reduction.

Langkah-langkah itu termasuk bagaimana melihat fenomena kedinamikaan dari suatu hal yang menarik perhatian pemodel. Hingga uji-uji yang dilakukan yang diperlukan agar model yng dibangun mampu menjawab permasalahan yang diangkat. Terakhir dibahas bagaimana strategi implementasinya dengan menggunakan skenario yang telah dibangun dengan pemodelan SD ini.

In particular, it has been hypothesized that through the use of a step-by-step system dynamics model building process SMEs' entrepreneurs can better understand the net of cause-and-effect relationships underlying company financial and non-financial results. Such an approach also enables decision makers to improve their understanding about the figures portrayed in a balance sheet. In order to reach such a goal, this study has been carried out through the use of a case-study. The small company investigated is a leather handcraft operating in Indonesia. The paper makes explicit main feedback mechanisms underlying company customer base dynamics adoption process, production and inventory management policies, human resource management practice and machineries production capacity acquisition policy.

The complexities’ exploration in the paper is based on the model of the policy cycle that is widely discussed in the public policy and public administration literatures. The sense of reality surroundings the policy-making process is perceived from some study cases that have been observed from Australia and Indonesia literatures. Such complexities will be described with system mapping through stocks and flows diagram and expectation on some variables behavior will be tested by system simulation.
Simulation throughout the paper revealed different complexities and some pitfalls in each stage of the policy cycle model on which should be given a proper attention from the policy stakeholder.
The paper tried to construct a different approach to understand the reality and embrace the complexities of the policy-making process in order to present a starting point for an open discussion in public policy field. The effort could be a learning tool for the public policy maker to build good awareness and understanding on their roles in the complex relationship and inter-dependent environment. Eventually, the paper can fill the gap between policy cycle model theory and the complexity in the real situation of the policy-making process."

Thus, the paper has objectives to discuss and propose policies such as; first, from operational side: providing market information in order to give more access for market demand, market capacity. This strategy will in the long term lead to a better production planning. Second, from the financing side: using profit-sharing principle of financing (PSP) to cope with such dynamics behavior in order to support a sustainable quantity growth of SMEs.
System dynamics approach is applied to understand this behavior. Some relevant variables included in the simulation model are potential demand, aggregate demand, and quantity of SMEs and LEs. Modular system of simple production coordination and a guarantee mechanism based on a PSP were attached to the generic system that has generated overshoot and collapse behavior, in order to minimize or even avoids the rapid decreasing number of SMEs in stock.
Simulation conducted in this paper has implemented two policy levers, which are first; a production coordination system through information sharing and second; financing mechanism with PSP contract for Small Enterprises (SEs). Based on the simulation done for this paper, such policy levers could support the development of SMEs in term of its quantity in order to keep it grow instead of “collapse.” The paper also shows the added value creation of PSP principle in economy and minimization of the agency risk with double layers referencing method.
This paper re-emphasizes first; the use of production coordination to support positive growth number of SMEs especially to prevent collapse after experiencing overshoot growth, and second; proposes a financing mechanism for SMEs based on PSP principle to prevent SMEs from the operational failure. This paper also proposes the use of double layer referencing system to minimize agency risk in the area of PSP contract agreement.
