Decision Architecture is a critical part of Enterprise Architecture (EA).  David Ullman has been working with TOGAF (The Open Group Architecture Forum) practitioners to bring robust decision methods into the EA world

Decision Architecture is: 

  • Aligning the best decision-making techniques to the problem at hand and the resources available
  • Building Robust Decisions - Decisions that look good later and that are as insensitive to noise as possible
  • Incorporating risk, uncertainty, and stakeholder concerns in business, application and technical decisions. 
  • Making use of a Decision Architecture Check List

 Decision Architecture is important because:

  • It structures the information that is key to the vetting and reuse of the rationale behind critical decisions
  • It can incorporate risk into decision-making.  Decisions are always based on projections into the unknowable and risky future.  A good architecture can make decision risks transparent.
  • It supports codifying those decisions that can be reduced to decision models and rules (i.e. structured), and supporting the resolution of those needing human intervention and characterized by uncertain information (unstructured).

 For structured situations:

  • It helps structure the logic of the business model.
  • It supports implementing automated decision making.

 For unstructured decisions:

  • It can enfranchise stakeholders by making them part of the decision-making process.  A decision is only as good as the buy-in by the stakeholders
  • It provides a systematic architecture can make decisions rational rather than emotional or political.
  • It helps manage information that is uncertain, incomplete, evolving and conflicting so that decision-makers can arrive at the most robust decision possible.
  • It supports choosing a decision making method that well matches the problem leading to significant ROI.
