As organizations become more process centered, business process modeling and analysis techniques are becoming critical for decision making. However, most modeling tools have important limitations that make them unsuitable for performing advanced analysis, such as the almost exclusive focus on the control domain. An even more severe limitation is the incapability of these tools to include in the analysis the structure and relationships between all the processes of an organization (the Business Process Architecture). This paper analyzes these problems and proposes a platform, BPA-Tool, that overcomes current limitations to offer more powerful business process analysis.
