It is difficult to determine the lessons learned based upon so few results and lack of any official reports for the alliance model. Some lessons learned from the interviews and comments from those involved in these types of projects are as follows:
• A new spirit of "team work" (seeking the best for the project instead of personal or organization gain. The relatively new "Alliance Model" is designed from this spirit - and is called the "Leadership Model")
• Co-location of the project partners is essential in the Alliance model
• Is the client able to be neutral party and assure quality practices
• How will the environmental approval processes be managed and resolved?
