To determine when a PPP is appropriate, we may consider the six Cs of PPP for the People (P4): Context, cash, competence, clock time, consequences, and contribution.
Context
Every PPP must begin with context. What is the problem? What is the situation on the ground? Is there a lack of potable water? Is flooding persistent? Is there congestion, inadequate hospital capacity, or insufficient classrooms?
A PPP should never start with the question, “What project can we offer to the private sector?” Instead, it must begin with, “What public need must be addressed?”
Context anchors the project to real people, real communities, and real deficiencies. Without a clear and documented public need, a PPP risks becoming a solution in search of a problem. PPPs solve problems.
Cash
The second C is cash. Does the government have sufficient funds to undertake the project on its own? If budgetary constraints delay or prevent essential infrastructure, a PPP may be viable.
Through private financing, capital can be mobilized without waiting for limited public appropriations.
However, PPP does not mean “free.” Investments must be recovered through user fees, availability payments, or other agreed mechanisms, which are performance-based.
The key question is whether private capital can accelerate delivery while ensuring value for money.

Competence
Even where funds are available, government agencies may lack the technical expertise, operational systems, or specialized experience required for complex projects such as bulk water supply systems, wastewater treatment plants, or smart infrastructure.
The third C, competence, asks whether the private sector can bring superior technology, managerial efficiency, innovation, or risk management capability.
PPPs are justified when the private partner’s expertise materially improves design, construction, operation, or maintenance outcomes.
Clock time
Time is not neutral. Delays in water supply mean prolonged hardship. Delays in hospitals mean avoidable suffering. The fourth C is clock time.
Private partners, driven by contractual incentives and return on investment, typically seek timely completion and early operation.
PPP contracts often impose milestone deadlines and performance-linked payments. PPPs accelerated project delivery — an effect known as “additionality” — as the private sector is expected to complete projects sooner rather than later.
Consequences
Traditional procurement tends to focus on specifications—what must be built and how. PPPs, by contrast, emphasize consequences or outputs.
Payments are often linked to performance indicators: water quality standards met, service continuity maintained, leakage reduced, uptime guaranteed.
If performance falls short, revenues are reduced. PPPs are therefore consequence-driven and output-based. This aligns private incentives with public service outcomes.
Contribution
Finally, PPP for the People requires contribution from both sides. The private sector contributes capital, expertise, and efficiency.
The government contributes regulatory support, right-of-way access, guarantees where appropriate, and policy stability.
Most importantly, the government must have “skin in the game.” It must monitor performance, enforce standards, and protect public interest. PPP is not abdication; it is collaboration.
The six Cs provide a disciplined lens for evaluating whether a PPP truly serves the public. When grounded in context, supported by cash viability, enhanced by competence, accelerated by clock time, measured by consequences, and sustained by mutual contribution, PPPs can indeed be for the people.
