Business Processes assessment

The ability to conduct assessment to:

a) identify appropriate business processes b) identify business process activities

Identify Business Processes


Business Capability Mapping

The ability to provide a holistic view of the enterprise and help prioritize agendas and roadmaps to focus enterprise efforts on high-priority capabilities first. This capability enables the creation of Business Capability Maps and Business Capability Heat Maps. This capability also helps support the development of Strategy Alignment Maps.

Decompose Business Capabilities


Business Capability Evaluation

The ability to identify critically important business capabilities and significant capability gaps with the purpose of ascertaining how critical a capability is in enabling the enterprise to achieve its goals. This capability helps determine how significant the gap is that exists between the current state and future states of the capability in relationship to the business processes, information flows, and IT systems that support them.

Develop Business Capability Evaluation Matrix


Heat Map development

The ability to create a business capability heat map by color-coding high-priority business capabilities on the business capability map.

Develop Business Capability Heat Map

System Architecture Review


The ability to work with Business Owners and System Owners to identify, describe, and catalog their existing, enhanced, new, and decommissioned IT systems within the enterprise. This includes reviewing stakeholder requests.



Integrated IT Systems Inventory

The ability to identify, reconcile, and validate IT systems, services, and Technologies from different types of repositories. This capability defines the key relationships and data flows required between repositories.

Maintain IT System Inventory in a Repository


Portfolio Management and Investment

The ability to collaborate with key stakeholders to maintain compliance and align systems, projects, and initiatives to strategic and mission objectives and ensure portfolio health.



Data Call Management

The ability to develop IT System Data Calls and execute those data calls by utilizing, and updating such as: Investments, Business Capabilities, IT Systems, and Technologies. This capability also routes data call requests to collect information on 1) New IT Systems, 2) IT Systems Undergoing Enhancements, 3) Existing IT Systems, and 4 ) Decommissioned IT Systems.



IT System Project Alignment to Business Capabilities

The ability to ensure new IT system projects/processes are categorized by (mapped to) Business Capabilities, in order to help ensure that new projects do not excessively duplicate existing functionality.

Map IT System Project Alignment to Business Capabilities


Baseline Mapping of IT Systems to Business Capabilities

The ability to vet the existing Business Capability-to-IT System Mappings with Business and IT stakeholders, making any modifications as required to correct the mappings.

Maintain IT-Systems to Business Capabilities mappings in a repository


Identify System/Technology Relationships

The ability to gather and analyze the relationships that exist between IT systems and their technology stacks (the set of software products used to configure the IT system), based on data available in a repository and other information sources.



Go/No-Go EA Recommendations

The ability to indicate where duplication exists; research the possibility of retiring older duplicative legacy functionality, and provide Go/No-Go EA recommendations regarding the new projects.


Technology Assessment


The ability to enable technical data exchanges between systems so that critical information is compliant with standards which allow it to be shared and discovered securely.



Technology Categorization

The ability to develop a new taxonomy or utilize an existing taxonomy that provides the means by which an organization can categorize (group) all technologies, both software and hardware, for the purposes of analysis and decision-making. This capability provides the basis for performing Scope and Boundary Definition, Technology Discovery and Aggregation, Market Research and Analysis, Technology Forecasting, and Technology Roadmap Development.
