New Public Management describes public-private partnerships (PPPs) where the private sector finances, designs, builds, maintains and operates infrastructure assets traditionally provided by the public sector. PPPs allow governments to take advantage of private sector efficiencies while the public sector provides legal authority and ensures public needs are met. Benefits of PPPs include risk mitigation, cost reductions, expertise, innovation and reduced waste. However, PPPs require more demanding processes than traditional procurement. When done correctly, PPPs allow the private sector to achieve what takes governments 50 years to do in a tenth of the time.
