It complexity involves: 
No. If software versions and brands
Hardware versions and brands
It services in diff versions and brands
No. Of coupling among systems 

Consequences of adding a new type of applications:

Bridging application had to be developed, maintained and updated

Question 7

Operating mode

Answer 7

Operating model is the necessary level of business process integration and standardisation for delivering goods and services to customers.

Coordination = low standardisation and high integration
Unification is high high
Diversification is low low
Replication is high standardisation and low integration

Question 8

Operating model: Business Integration

Answer 8

Business process integration is the extent tot which business units share data. Share data between related processes to enable end to end processing.

Question 9

OpeRating model: business standardisation

Question 10

How IT helps innovation

Answer 10

Chain:

It enabled potential absorptive capacity (firms abilities to manage knowledge, eg databases, document management systems)

It enable realised absorptive capacity (leverage the knowledge that firms absorbed eye data mining, simulations, visualisation)

Idealer innovation ( knowledge created through firms inventions eg no of patent applications of a firm)

Commercialised innovation - market available ideas eg no. Of products introduced into market

It enabled social integration capacity: it that enables the development of social capital through direct human interactions and discourse (eg conference of messaging
