Did Not Finish: Status Quo. Client provides a problem for the engineer to solve. Engineer maximizes utility while minimizing the cost to the client. Short term solution to the symptom of an underlying problem.

D: Level 1 Green Engineering. Client asks for a broader perspective from the engineer. Engineer maximizes utility while minimizing the cost to the client, and uses indicators (TBL, etc.) or critieria (LEED, Envision, etc.) to provide rationale for the broader perspective of ‘utility’. Probably long term solution to the symptom of an underlying problem. Bonus marks available if method addresses social justice in a meaningful way.

C: Level 2 Engineering for Resilience. Client asks for an underlying problem to be solved. Engineer uses community data to determine the greatest Potential Quality of Life (PQoL) that can be obtained through Technological Development. Long term solution to the problem identified by symptoms provided by the client.

B: Level 3 Sustainability Engineering. Client asks engineer to identify the underlying problems and find the greatest possible improvement in the Actualized Quality of Life (AQoL). Engineer involves Human Development professionals to find how to work around the obstructions within society that prevent the PQoL from being Actualized. Long term solution to underlying problems using technological development.

A: Level 4 Undefined but required future condition. Client identifies that symptoms to problems exist. Human Development Professionals identify all obstructions within community and determine the means to remove them. Engineer provides appropriate T.D. solution once problems being solved can be done most economically (eg, when T.D. is the lowest hanging fruit). Problems are solved in most efficient manner available to community.
