ISORG Question : Can use all 3 models for one company?

[Winson Sim]

Hi Mr Toh,

Is it possible to describe different aspects of a single company using each of the 3 theories?

For example a car manufacturer uses:

Data Model to redesign its manufacturing/assembly line and process flows along inventory-assembly-painting-finishing,

and

Decision Making Model to design for example KWS, DSS, and ESS for managers and workers to make better decisions,

and

Transaction Cost Model to design its SCM system with its suppliers and retailers, and perhaps it's own e-commerce site.

Or do the 3 models only have to focus on one aspect of a business? (For example Laundry Network using DM for it's BPR means it doesn't use the DMM and TCM)

Thank you!
