Silos, mousetraps, and islands

a chronicle of information systems in organizations

objectives develop sense of context for:

organizations information technology information systems

describe some of advances and failures of the old context

why organize? division of labor

manage complexity achieve mastery reduce switching costs reduce training costs increase scalability

A single, unified task…

…naturally divides into subtasks

specialization & control

resulting in task specialization

and increased need for control

coordinating mechanisms mutual adjustment direct supervision standardization of tasks standardization of outputs standardization of skills

Mintzberg, 1979

3 PEOPLE = 3 CHANNELS

6 PEOPLE = 6 CHANNELS???

the flow of formal authority

the flow of regulated activity

the flow of informal communication

set of work constellations

an organizational mess

failure to integrate focus on task and individual over process and

team grouping by function discourages lacks built-in mechanism for coordinating

process flows coordination problems rise to level to far from

origin loss of big picture; overall performance hard

to track

monopoly; focus on efficiency & productivity

Era II – proliferation of PCs; free market; focus on individual & group effectiveness

Era III – network is computer; ubiquity; focus on integration & value creation
