Building effective and efficient contribution collection and compliance systems involves long-term political and administrative projects. A large number of success and risk factors can be identified only during these processes. Furthermore, experience and institutional capacity are obtained mainly through practical projects. Successful social security systems rely strongly on acceptance and adoption by society overall, whatever the country. Therefore, continuous improvement approaches based on permanent evaluation and adjustment, and ultimately on maturity management, must be put into practice.

While the strategic plan and corresponding performance model constitute the main inputs to permanent evaluation and adjustment, a long-term approach aiming at incremental institutional strengthening is also needed.

The ISSA Guidelines on Service Quality provide further guidance on continuous improvement.
