Here’s a detailed RAID log (Risks, Assumptions, Issues, and Dependencies) with mitigation strategies, tailored for the Digital Banking Transformation: Customer Engagement Modernization roadmap.

🧾 RAID Log + Mitigation Plan

🛑 R – Risks

ID	Risk Description	Impact	Likelihood	Mitigation Plan
R1	GenAI responses may hallucinate or provide incorrect advice	High	Medium	Implement strict retrieval-augmented generation (RAG), human-in-the-loop review, use curated knowledge base
R2	Data privacy issues during cloud migration	High	High	Masking & encryption of PII, compliance with RBI data localization, VPC design, DLP tooling
R3	User resistance to chatbot adoption	Medium	High	Conduct awareness campaigns, training, human fallback, phased rollout
R4	Integration delays with legacy systems	High	Medium	Create abstraction layers via APIs/middleware, parallel run plan, dedicated integration sprints
R5	Vendor lock-in with cloud platforms	Medium	Medium	Use containerized workloads, IaC for portability, avoid proprietary services when possible

🧠 A – Assumptions

ID	Assumption	Validation Approach
A1	Key stakeholders will be available for workshops and reviews	Confirm stakeholder buy-in with steering committee and calendar blocks
A2	Cloud budget approvals will be granted in time	Engage finance early, include phased budgeting plan
A3	Customer data sources are accessible and accurate	Conduct a data audit in Phase 1, set up data profiling and lineage tools
A4	Regulatory compliance won't change mid-project	Keep compliance team involved in governance reviews every sprint
A5	Team has basic familiarity with cloud and GenAI concepts	Arrange enablement sessions during Phase 0 (pre-project ramp-up)

🐞 I – Issues

ID	Issue Description	Severity	Resolution Plan
I1	Delay in CRM migration due to data mapping inconsistencies	High	Assign data SME, use ETL tools with data validation and reconciliation scripts
I2	Low quality of chatbot initial responses during UAT	Medium	Enhance prompt tuning, fine-tune LLMs with internal data, add contextual memory
I3	Deployment failure in staging due to IAM misconfigurations	High	Implement IaC with automated security scans, enforce pre-prod access reviews
I4	Stakeholder feedback loop too slow for agile sprints	Medium	Set up fast-track feedback process (Slack + scheduled demo slots)
I5	Disjointed customer feedback from different touchpoints	Medium	Set up unified VOC (voice of customer) pipeline with analytics dashboard

🔗 D – Dependencies

ID	Dependency	Type	Plan to Manage
D1	CRM vendor (Salesforce) onboarding timeline	External	Add buffer in Phase 1 timeline, pre-negotiate onboarding SLAs
D2	Availability of sandbox for GenAI PoC	Technical	Request early cloud provisioning, use internal GPUs temporarily if delayed
D3	Legal approval for GenAI content use	Regulatory	Engage legal team in sprint 1, define prompt & output boundaries upfront
D4	DevOps pipeline maturity for production rollout	Internal	Allocate dedicated DevOps resources, prioritize pipeline hardening tasks
D5	Mobile app team to integrate GenAI APIs	Cross-team	Include mobile devs in GenAI squad, API-first documentation and mocks
