Arbetsflöden som används på Chalmers bör spegla dem som används på hög nivå i branschen. Där ingår modern versionhantering. Genom att införliva versionhantering i arbetet med inlämningsuppgifter läggs en stabil grund inför arbetslivet. Därtill är Fire-systemet, det nuvarande systemet för hantering av inlämningsuppgifter, undermåligt av följande anledningar:
