Cost and value

IT or information technology has two parts: information and technology.  Using a simplified view the value is largely in the information and the cost is largely in the technology

 

 

Value Costs
Information Information acquired

Processed (value added)

Transferred (value returned)

Time

Effort

Storage

Maintenance

Technology Efficiency (reducing costs)

 

Effectiveness (adding value): by increased accuracy, completeness, currency, timeliness ...

Hardware

Software

Training

Operating

Vulnerability

Maintenance

Development

Facilities

 

Thus it might be useful to think in terms of the cost-benefit ratio of information and the cost benefit ratio of the technology.

 

Clearly in both cases the benefits (value of the information) should be substantially greater than the total cost of working with the information and the means to do so.

 

Anecdote: My dentist no longer uses a computer to handle bookings - the practice (1 full-time and 2 part-time) has gone back to the traditional appointment book. The judgment has been made that cost of failure of the technology far outweighs the benefits involved. The decision to abandon their IT was presumably based on the judgement that the (added) value of the information using the computer did not justify the costs of the computer. [Note: the decision may have been sound but no doubt there were other possibilities such as develop the system in some way.... and this would, presumably, involve both costs and benefits.
