Collaboration between MDH, Chalmers, GU, SICS, Swedsoft, BTHUltimate goal: A Software Engineering Master’s Education for IndustryPractitionersCurrent Status: Four pilot courses:
Agile and Lean (BTH)Functional Safety (MDH)Project Course (MDH)Software Testing (SICS/MDH)
Focus is to find methods for teaching that enables studying andlearning in combination with a job in industry

VSM – Value Stream Mapping
Analyse a process flow and identify wastesOriginally from manufacturing industry, some translation into softwareengineering is needed:
Lean manufacturing Software developmentInventory W1: Partially performed workOverproduction W2: Extra featuresExtra processing W3: Extra processesTransportation W4: HandoversMotion W5: Motion/task switchingWaiting W6: DelaysDefects W7: Defects
