PPP arrangements are considered successful when they result in a win-win situation for both the public entity and the private partner. The interests of the public entity in a PPP arrangement are as follows:

1. PPP arrangements are a means to harness private sector efficiencies such as on-time and on-budget delivery and access to the latest technology

2. PPPs also augment public resources

3. They ensure value for the project

4. There is continuity in service delivery, which benefits the community

5. All laws and regulations are complied with, such as environmental protection and fair tariff setting

Likewise, the interests of the private partner from a PPP arrangement are as follows:

1. PPP arrangements are usually viable ventures that create long term business opportunities and ensure reasonable profits

2. Fair allocation of risks between the public entity and the private partner

3. Presence of transparent laws/regulations

4. Stability in the political and economic environment

Although, the interests and expectations of the public entity and the private partner from a PPP arrangement are different, a well-structured PPP arrangement can align the interests of both parties and lead to effective service/ project delivery.
