Risicobuffers

Risicobuffers are reserves of time, money, or other resources set aside within a project plan to absorb uncertainty and protect objectives from adverse developments. They are a component of risk management and project scheduling, providing a cushion when estimates prove optimistic or when new risks materialize. Buffers differ from explicit risk responses in that they address overall uncertainty rather than a single identified risk.

Common types of risicobuffers include schedule buffers, cost buffers, and management reserves. Schedule buffers are extra time added to activity sequences or milestones to absorb delays. Cost buffers are additional funds allocated to cover unexpected expenses or price fluctuations. Management reserves are funds or resources not allocated to any specific activity and are controlled by governance bodies to respond to unforeseen events.

Determining the size and placement of buffers typically relies on risk assessment. Qualitative assessments of probability and impact can guide initial buffer levels, while quantitative methods such as Monte Carlo simulations or probabilistic scheduling can provide more data-driven estimates. Buffers are usually sized according to the project’s risk exposure, criticality, and the organization’s tolerance for schedule or budget variation.

Implementation and monitoring involve integrating buffers into the plan, placing schedule buffers along the timeline or at the end of the critical path, and maintaining governance for managing management reserves. Buffers should be reviewed regularly as risks change or are mitigated. Transparent tracking of buffer usage helps maintain realism and avoids unnecessary padding.

Risicobuffers are most effective when combined with active risk management, clear governance, and ongoing risk reviews. They support predictability without replacing proactive risk mitigation.
