• Have in place coherent and stable institutional, legal and regulatory frameworks, which are essential to increase participation in doing business with the public sector and key starting points to assure sustainable and efficient public procurement systems.
• Deliver clear and integrated tender documentation, standardised where possible and proportionate to the need.
• Use competitive tendering and limit the use of exceptions and single-source procurement. 

• Transparency
• Integrity
• Balance
• Participation
• Efficiency
• E-procurement
• Capacity

• A use of exceptions to competitive tendering (direct awards, accelerated procedures, etc.), which restrains competition and undermines the administrative efficiency of procurement;
• Complex public procurement rules and the use of non-standardised bidding documents impede  broad participation from potential competitors, including new entrants and SMEs; and
• Obstacles (regulatory burden, financial constraints, lack of technical expertise, request for bribes) faced by SMEs for participating in public procurement processes.
