How often may a sustainment appraisal be conducted after a Benchmark appraisal while the Organizational Unit remains eligible?

A sustainment appraisal can be conducted every 24 months after a Benchmark appraisal, as long as the Organizational Unit maintains its eligibility. This period is established to ensure that the organization continues to meet the standards and practices defined in the Capability Maturity Model Integration (CMMI). The 24-month timeframe allows organizations to assess their improvements and make necessary adjustments to sustain and enhance their process maturity without overwhelming them with more frequent appraisals. This balance helps organizations focus on continuous improvement while providing enough time for implementing changes and measuring their effectiveness.
