Six Sigma in Projects? No

Dileep, in my opinion, it is not whether Six Sigma (SS) is applicable to LA or not, it is more that SS is applicable to operations (such as manufacturing or service operations), but not to projects.
Sorry if this is already understood by you, but while in operations you're dealing with ongoing repeatable tasks, a project has an end (in simple terms).
The LA work you describe is a project. To measure the quality of a project (and its management), I suggest you use the QMS applicable to your project methodology (e.g., PRINCE2).
