There are four ways that the Government and the private sector can enter into a partnership.
1. Solicited Project. A project with commercial qualities where the Government offers a tender allows private investors to bring a document and whoever has a good document then gets a chance. 
2. Unsolicited project.  The private sector sees how the Government does it at a loss, but if you do it, you can do it for a profit. You don't need to wait for a bid, but you write the text yourself (unsolicited)
3. Direct negotiations. The agreement that the government needs the project urgently so if the process goes normal it will take time so the relevant authority is allowed to find the private sector and talk to them directly so that the project can be completed on time. (direct negotiation)
4. Special arrangement.  Special agreements that occur where the law is set but there are things that were not observed. There are projects that will get stuck and then they sit and talk about it again. This shows the willingness of the Government to work with the private sector - Director of the Center for Partnership between the Public and Private Sector (PPPC) Mr. David Kafulila.
