A short checklist before starting your initiative:
- Start with stakeholder interviews to understand the business goal and define the expected business outcomes.
- Follow up with the current-state mapping: systems, processes, data flows, security posture, and vendor landscape.
- Create the AS-IS -> TO-BE roadmap, highlighting risks and constraints.
- Decompose that roadmap into several development iterations.
Maintain your focus on the business goals at all times to maximize the chance of success.
Technology choices introduce distractions - keep them in check.
Good luck!
