A playbook documents a repeatable modernization pattern or process, grounded in a real example that has verified the approach. Teams use it when they are ready to modernize, rather than waiting for centrally assigned dates. section 16.3.1
A modernization playbook typically includes:
- A general overview and criteria for choosing the playbook. section 16.3.1
- Prerequisites, the process or pattern to follow, and examples of initiatives that applied it. section 16.3.1
- Responsible teams, contact details, general advice, and practical tips. section 16.3.1
Playbooks help many teams reuse expert-verified approaches and reduce dependence on scarce centralized expertise. They can also reduce upfront sequencing and planning, but they do not remove prioritization or central coordination: modernization may be deferred, and initiative timing can inform which playbooks to create first. section 16.3.1 section 16.3.3
Modernizing a legacy API
An organization can document how to modernize a legacy on-premises Java API in the cloud according to its conventions, using a verified initiative as the playbook’s foundation. Early applications may require approval from a governance team; later, peer teams that have already used the playbook can provide approval instead. section 16.3.1
