- Selecting components and assemble chassis can start together
- Build components can only be done once chassis is assembled, and components are selected
- Configure cooling system can be done when build components is complete
- Install software can be done when cooling system is installed
- System testing can be done when all software is installed
- Prepare user documents can be done after build components
- Invoice customer can be done after system testing and prepare user documents are complete
