Local governments change over time. The internal and external environment dynamics of change pose additional, often different risks and threats, as well as, opportunities. Implementation of risk treatment measures affects exposure to risks.

Changes in the human resources, such as, change in the political leadership, turnover of personnel, have a direct immediate effect on the human parameters of the maintained integrity management system. New services or integration of services (i.e. integrated services or one-stop shop) could eliminate certain risks, but also give rise to others. New sub-contractors and partners bring new development opportunities, as well as, new challenges. Amendment of legal acts makes the regulatory environment different and requires appropriate adjustment. All of the above points highlight the need of local governments to periodically reassess risks and reconsider the adequacy and effectiveness of the selected risk management policies and controls.

There is no universally recognised rule as to how often re-assessment of the integrity risks should be done. The prevailing approach is to give the system a chance to develop and demonstrate its effects and to provide time for the integrity measures to produce effect, and correspondingly have the new round within two or three years following the adoption of the Integrity Plan. This depends on the time period selected for the Integrity Plan and should be based on a decision from the top management.

However, in case of exceptional circumstances, such as new or emerging risks, changing policy or organisational conditions, serious threats, etc. that can cause important changes to individual risks and the level of impact of these risks, the top management may decide to undertake integrity planning earlier. The re-assessment process should be built on the results and experience of implementing the integrity plan, considering the lessons learned from the implementation so far.

It is important to secure the continuity of the integrity management system in this time of change and to try and learn as much as possible from past achievements, as well as from past failures. In case there are evaluation reports, they also need to be studied and used for the re-assessment.
