Decay of IT - usually leads to Disaster
- decay process - slow and insidious
- disaster event - fast and obvious
software does not wear out (and hardware, very slowly),
but software decays:
brittle architecture, unable to adapt to
component upgrades - hidden dependencies exposed
mission creep - typical of IT, consider Peter's Law
maintenance - bug repair introduces bugs
resource issues
workload change - mission creep, victim of own success
loss of connectivity and/or power - network as roads: capacity yields congestion
loss of provider and/or know-how
consider bit rot
loss of information because of loss of means to read it!!
how many (format) versions of MS Word have you used?
how many removable storage (floppy, tape, CD, zip...)?
