In the support phase, the implementation team should address the following milestones:

• Support/sustenance plan: This is an important aspect of keeping your solution healthy.
• Team spanning at varying levels to support needs: Maintaining a tiered support approach helps in timely and accurate issue resolution.
• Enhancement initiatives: Something is always chosen to be done later and having a product catalog for all changes/enhancements is key to ever-evolving your solution.
• Good-to-have business needs from RTM: After all must-have requirements are met, it is now time to cover good-to-have requirements.
• Issue portal: This is a single repository to manage issues and triaging and solutions and can be combined with knowledge management.
• Ongoing training, roll-out initiatives, and others: After the core solution is in place, it is now time to roll it out.

You will learn more about the preceding in subsequent chapters.

You should treat the aforementioned phases as a starting point, and we recommend that you leverage the CRP methodology concepts, PMI, and other useful resources to come up with your project-specific deliverables and milestones.

Now that you have gained information about all three methodologies, it is time to do a side-by-side comparison, which becomes your checklist for selection.
