Enterprise Architecture (EA) has been applied widely in industry as it brings important benefits to ease communication and improve business-IT alignment. However, various challenges were also reported due to the difficulty and complexity of applying it. Some empirical studies showed that EA stilled played a limited role in many organizations. In this research, we showed other findings where the potential of EA could be better used. They are derived from our analysis of advanced EA tool recommendations. Based on these findings, we proposed four essential EA practices and the rationales behind them in order to improve the understanding of current practices and bring insights for future studies to boost the potential of EA.
