Business model / System functionality

• BM uses concepts such as goal, process, actor
  and role
• SFM deals with object, operation and event
• Aligning business models and system
  functionality
• Aligment takes place during an ERP customising
  activity

In ERP installation projects ERP experts and
organisational stakeholders have difficulty to

Introducing the Map

non-deterministic ordering of intentions and
strategies
