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??? 6 PEOPLE = 15 CHANNELS 12 PEOPLE = ???
functional organization

Mintzberg’s form strategic apex operating core middle line support staff techno- structure
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
Moore’s Law K 100K 1M 10M transistors mips Merced Pentium
generations 1 st – vacuum tubes 2 nd – transistors 3 rd – integrated circuits 4 th – large-scale integration
failure to communicate connectivity is more than technical issue organizational inertia and legacy systems standards cut both ways responsiveness is remote

IS management eras Era I – the glass house; regulated 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 Applegate et al, 1999
