Validation can also be sought by further investigation of the principles underlying Tema in order to see if these may hold in other projects as well. Doing repeated studies of enterprise modeling with the same perspective as taken in this research project may establish more confidence in both the principles and the framework. These repeated studies may benefit from the understanding developed in this thesis, enabling a tighter research design than applied in this research project.
Another extension of Tema would be to integrate principles that pertain to other aspects into the framework. As discussed in section 10.4.2, aspects like economy or actor power have not been considered in the studies. Hence, conducting studies (either empirically or literature based) that focus on these aspects may make the framework more effective, as it provides more support to the modelers.
A final extension of Tema would be to develop alternative components that meet the requirements posed by the principles. E.g., Tema calls for the inclusion of explanations with enterprise models when they are disseminated, as a complementary device for the enterprise audience. As for now, Tema proposes a simple textual account of model elements. However, introducing an active model guide to visualize explanations and introduce animation might be an alternative.
