This paper describes how Mile Two has attempted to integrate CSE with other disciplines in order to design software to support decision making in joint cognitive systems. The paper discusses three aspects of our approach: 1) Recognizing the value and limitation of different design perspectives; 2) Cross-training; and 3) Involving all disciplines at all stage of the design process - co-creation. The paper will discuss the successes and difficulties associated with implementing a total team process across different stages of design and development.
