**4. Model of integrating between various information systems**

In introducing the information subsystem for developing an automatic calculation part, more time becomes available for persons working in the production sector which can then be used for improving the quality and additional production control. Figure 2 presents an organizational scheme with an automation and calculation part which was expanded from the subsystem base.

A new, expanded organizational production scheme was obtained based on two different information systems – financial-material (serves for a complete financial part which includes prices of material, production activities and resources, creation of all business documents and reports) and production (development of working versions of tenders, complete production planning, time and status reports of individual activities – work orders).

The integration part which links the two information systems communicates by transferring information for production, i.e. current prices of materials, articles, resources as well as the appropriate conversion of necessary elements for the production cycle. The integrated interface enables the transfer of necessary information for the production calculation considering that in such a scheme those elements are entered through the financial-material

From the production part, the final project yields a final calculation of the work order and the results are sent for finalization into the financial-material system. In the construction of a model presented in Figure 2 requests by the production organization itself had to be taken into consideration. They refer to the transition period of training workers in other sectors. Training refers to acquisition of knowledge which defines the final product in the maximal capacities of the organization itself, and expanded with other elements that can be upgraded

Considering that such knowledge is broad and concrete it is inevitable that a significant amount of time for their acquisition is necessary as well as for their actual application. The period of training can last for several years because of the work activities which are present

In comparison with the basic model, production planning, time and status reports were introduced. This includes a variable digital display of the load of all production resources through a varied period of time; from daily to weekly planning using an automatic system of confirming an offer as an order. The internal web interface transfers the automatic calculations according to clients' requests through the financial-material information system. In that way the existing communication between the client and production organization is maintained. Completed post calculations are also transferred according to the financial

Further enhancement in the restructuring of the existing links and appropriate activities which can accelerate communication with the external client and communication within the organization itself is shown in the model in Figure 2. Figure 3 represents a significant reorganization primarily through communicative activities with external clients which take place directly through the production system. In order for the presented model to become active in the organization it is necessary to carry out a reorganization of work activities and knowledge of people participating in the production process. This is evident in positions in

In the previous model (Figure 2) the final document is generated in the financial-material system to which the entire calculation part for the ordered product is transferred. This leaves the possibility for correcting the suggested price (adding workers or changing the

The advanced way offers possibilities of direct – automatic communication in the clientproduction communication through which the calculations are generated as valid business documents. At that level, the client must take responsibility of correctly defining elements for the finished product (e.g. through a web interface), since based on those specification an automatic project for the finished product is created. An offer is generated based on the confirmed order and work order as well as complete production planning of

Having such a system enables the client to see and monitor all the production processes defined. Information systems without such options of "openness" towards clients (independent work specification and product monitoring) are extremely complex and demanding, and their implementation is possible only in rare systems which already have

Only organizations like that can expect an increased number of orders and work orders which opens an area for further quality investment into production resources and training of people who can manage such complex production structures. Figure 4 presents a highly computerized production model in which the interaction of the system with the external client is minimal. This enables rapid information searches which will manage further business activities on the client's side. Such a model enables independent creation and change of desired input parameters by the client with immediate results for the desired

Such an advanced business organizational model yields extra work time which can be further directed to planning, development and control of the final product for the purpose of obtaining a more quality and more competitive product. This also leads to room for creating new products whose construction is based on the existing base by extending it to new production resources. By expanding the production capacity and resources there is a possibility for selecting different production directions in order to obtain a cheaper yet high quality product as well as obtaining a sequence of cost-effectiveness of various technological

With the existence of a module for planning and monitoring production it is possible to visually control the suggested processes and resource occupancy, and thuds influence their change and reorganization (automatic re-calculation for the resources of necessary time and people). In such a way production management becomes simpler, controlled and transparent making the time for locating production congestion and delay almost

To make the information system was more comprehensive and effective; it is further proposed the implementation of subsystems for feedback generating information that can further affect the input values for the appointing calculation of the finished product. Through this subsystem performs the correction of the set current value, which affects the gain of the new planning and calculation production parts. Permanent changes in factors
