Baseline Assessment involves the analysis of the Enterprise's capabilities in the current state. It is conducted to identify opportunities that will improve capability areas that are under-performing. It also provides input for considering the reuse of existing capabilities, where appropriate, to develop target architectures. This may be Enterprise-wide or within a designated area that is pertinent to the client's focus. Using the Proact Toolkit, current capabilities are captured, aligned, and categorized in accordance with the associated reference model. This provides revealing clarity where diverse and overlapping solutions exist.

The Proact Methodology does not encourage nor require the creation of "as-is" models in order to proceed with Baseline Assessment and Target Architecture Development. It is usually sufficient to characterize the current situation and use the knowledge of subject matter experts to map the current state to the structure and classification represented by the associated industry-specific reference models.

In addition, the intuitive representation of Proact's service function models makes baseline assessments easy to organize and conduct. Specifically, each basic service function is identified as a point of reference for its defined capabilities. After the appropriate performance metrics and measures are applied to these functions, the areas that can deliver high-impact business-driven opportunities become readily apparent.
