CAM Variance February 2026

There is a cumulative schedule variance of -$702k in the cost account 402.04.04.04 CE - Standard Module Assembly Site 2 (CMU). The variance is from the assembly and testing of the first 48% of modules and the associated cleanroom consumables.

This variance is expected, primarily due to missing input parts (baseplates). CMU has received baseplates has resumed production in January and February. Shipment of the CuT baseplates from UCSB are arrivig soon. CMU has demonstrated the 12 modules / day protocol now. We are currently hiring another technician to get us up to 16/day.

There is a cumulative cost variance of -$526k in cost account 402.04.04.04 CE - Standard Module Assembly Site 2. This is expected and is consistent with the cumulative schedule variance discussed below. Schedule delays, due to missing input parts, have caused cost variance resulting from labor costs not earning value.

The activities contributing to this variance are due to upstream delays in receiving input components needed for the final module test stands, resulting in completion later than scheduled. Once the components become available, the value will be earned, and it should not impact the overall schedule.

There is a cumulative schedule variance of -$765k in cost account 402.04.04.05 CE - Module Assembly at UCSB. The variance has two components: most (90%) is due to the assembly, testing, and shipping of full-size equivalent odd-sized modules (1-48%); the remainder is for supporting production at other assembly sites. This past month UCSB has continued to produce modules with 16/day protocol and is catching up earning value given the availible input parts.

There is a cumulative cost variance of -$977k in cost account 402.04.04.05 CE - Module Assembly at UCSB. This is expected and is consistent with the cumulative schedule variance discussed above. Schedule delays, due to missing input parts, have caused cost variance resulting from labor costs not earning value.
