Digital Transformation and Information Systems
What this domain tests
Digital Transformation and Information Systems tests the business case for platform change, data governance, and the controls that must survive a move to cloud and AI.
Core rules and concepts
- Digitisation versus transformation - digitisation converts an artefact; transformation changes the operating model, decision rights and process ownership.
- ERP logic - a single source of truth requires process harmonisation. Local statutory, fiscal and language requirements are handled through a localisation layer, not by forking the template.
- Cloud models - IaaS, PaaS, SaaS; shared responsibility means the provider secures the infrastructure while you still own identity, configuration and data classification.
- Data governance - ownership, master data management, data quality rules, lineage and retention.
- Architecture - TOGAF ADM for enterprise architecture; APIs and event-driven integration instead of point-to-point sprawl; RPA for narrow, rules-based tasks, not as a fix for broken processes.
- Security - CIA triad, NIST CSF functions (govern, identify, protect, detect, respond, recover), zero trust, least privilege.
- Value - total cost of ownership includes licences, implementation, integration, change management, run costs and technical debt; benefits materialise only with adoption.
Worked example
A manufacturer weighs a single global ERP template against regional instances. Licence $2m, implementation $6m, run $1.5m per year. Benefits: inventory reduction $1.2m and headcount $0.8m per year, so $2.0m per year. Five-year cost = 2 + 6 + (1.5 x 5) = $15.5m. Five-year benefits = $10m. Net = -$5.5m, with payback at 8 / 2 = 4 years, so the case only closes beyond year four or with further benefits such as reduced audit and compliance effort. Regional instances cut localisation risk but add integration and master-data reconciliation cost. A defensible recommendation: one template plus a controlled localisation layer for tax and statutory reporting, because benefits come from harmonised processes while statutory compliance is non-negotiable.
Traps that cost marks
- Counting licence cost as the project cost and ignoring change management.
- Assuming cloud migration transfers GDPR or sector compliance obligations to the vendor.
- Claiming benefits before adoption is measured.
- Choosing bespoke build where a configurable standard process would serve.
- Underestimating data migration quality and record-retention constraints.
