E l l l After the execution session interruption the logical execution thread was not broken it can be continued if the Object Space execution is started again The readers are encouraged to finish the exercise until Vera s final victory The following figure shows the final position ae The simulation was executed successfully This means that the conceptual model is correct and that it forms a solid base for further development The detail class model specification may follow Step 4 of this document or maybe direct transformation to the corresponding detail design or code There are different possible scenarios of following steps but the most important is that after exhaustive class model simulation we have some indicators that tell us that the analysis process has been done correctly O In the case of more complex systems models it is most probable that some additional problems will occur during the model execution In those cases the conceptual model should be reviewed fixed and improved the model should be recompiled and the critical part of the execution should be repeated This process is highly iterative and leads to a model that supports all projected scenarios Besides the conceptual class model the system use cases and or test cases will typically form an input to this kind of simulation The preconditions post conditions and some critical or all use case steps might be simulated using the propose

This model is not optimal If we analyze this solution more profoundly a serious limitation is noted a Player sign is modeled as his permanent feature In other words this model obliges Players to always play the same Sign A further consequence of this is that two Players with the same Sign could never play against each other without the Sign reassignment of course but this leaves us with new problem how to follow a game history Anyway the starting assumption is not real and we need to modify the model looking for a better abstraction of the situation the one that would be more close to reality et TARN ARE Be ENTERPRISE ANALYST Enterprise Analysis for an Enterprise Architecture The following model segment fixes the problem me lt a participate in players Player game date date g zenumeration Sign Now the Sign is not a Player s exclusive feature but a feature of the relationship between the Player and a Game This makes those two concepts independent in the context of a Game To finish the initial Tic Tac Toe game modeling the Moves should be incorporated After adding this concept and joining the parts in a whole the final model is ready lt a participate in players Player enumeration Participation sign sign ie moves 0 5 moves captures m i l fieldy je consists of w g horizontal int vertical int et TAN ARE ENTERPRISEANALYST Enterpris
