Corrective recommendations

Corrective recommendations are those issues that were studied in detail in the GIGAS project. Their analysis is considered to have converged sufficiently to lead to a corrective (technical) recommendation. Up to now, the current GIGAS analysis activity has led to the following recommendations:
