Hi Viacheslav,
The implementation lifecycle using Solution Manager is:
1 - Define your system landscape (development, quality, production systems)
2 - Associate your system landscape to a Logical Component (e.g. for ERP) which comprises all environment rules you set in your system landscape
3 - Define which business scenarios/processes/process steps you will use
4 - Configure the system to enable the business processes
5 - Test/Approve the configurations made
6 - Promote your projects to production. At this point, you will close your implementation project and transfer your business process tree/documentation to a "solution" which is used to monitor how your business process are being performed productively and over time you may encounter some points that require adjustments/enhancements
7 - Create maintenance projects with the branch of business process that need to be change and go back to tem 4 ( items 4-7 will represent your continuous improvement).
