  Emerging technologies and business models require organisations to
continuously deal with complex, dynamic and unstructured issues, leading to the
need for newer forms of decision support systems (DSS). However, in emerging
environments the existing knowledge base can be scattered, unstructured, and
sometimes conflicting, which challenges any efforts in designing DSS. This
paper highlights the role of design science methods in developing these
emerging areas, and suggests a design science method that focuses on
consolidating the knowledge base by ontologically grounding experience and
expertise. The proposed method is illustrated in the context of a published
case, and validated by practically applying it to develop a crowdsourcing
decision tool. The study contributes with recommendations on how to consolidate
the knowledge base and design DSS artefacts.
