Change Management
This process primarily targets requests that can be handled with current level of effort (LOE) resources. This process is also designed to detect and redirect items to the EVMS process if they exceed LOE resources.
Successful changes proceed through 5 stages:
1 | Business Case & T/CAM Concurrence | Check that the submitter has stated a plausible business case and the relevant T/CAM agrees |
2 | Feasibility | Is the change well-formulated, address a project need and |
3 | Planning | A detailed implementation plan is created which takes into account impacts, resource needs, testing and verification. |
4 | Insertion | The plan is executed to implement the change. |
5 | Assessment | Verification of successful change, issues analysis, documentation and close-out. |

Key | Summary | Process Stage† | Reporter | P | Created | Status |
---|---|---|---|---|---|---|
IHS-576 | Planning | Tim Morton | 02/Nov/17 | This change has been approved and is tentatively scheduled for early CY18. | ||
IHS-580 | DM developers need a build/test environment that supports docker containers | Feasibility | Joshua Hoblitt | 02/Nov/17 | Use case and requirements are being gathered. Unknown User (pdomagala) with the PDAC working group last week. They requested further detail on the specifications and timing of the FY18 kubernetes/docker initiative. If that service, even an early implementation, is ready near-term, the need for stop-gap measures may be unnecessary. | |
IHS-612 | Implement debug and normal queues for developers on the verification cluster | Planning | Yusra AlSayyad | 16/Nov/17 | Currently being planned and tested. Tentatively scheduled for early CY18. | |
RFC-423 | Allow ssh access to verification cluster worker nodes | Feasibility | Simon Krughoff | 18/Dec/17 | Proposed. 5 days left on comment period. |
