Privacy Commissioner of Canada's guidelines for fingerprint use

Covert collection: People should be informed if their personal information is being collected.
Cross-matching: Personal information should only be used for the purpose for which it was collected.
Secondary Information: Personal information should only be collected for a clearly identified purpose.

smell test:
Necessity: Is the measure demonstrably necessary to meet a specific need?
Effectiveness: Is it likely to be effective in meeting that need?
Proportionality: Would the loss of privacy be proportionate to the benefit gained?
Alternatives: Is there a less privacy-invasive way of achieving the same end?

guidelines for implementation:
record only summary information
use only for verification, not identification
store locally, rather than in central databases

many unintended consequences of the misuse of metrics that Muller cites are the following:
Inducing people whose performance is measured to divert their efforts to what gets measured;
Promoting short-termism (as in Wall Street's obsessive preoccupation with quarterly earnings reports at the expense of companies' long-term health);
Discouraging innovation and risk-taking;
Sidetracking nonprofit staff members (or corporate employees, for that matter) from focusing on the mission that motivates them; and
** Forcing employees to spend time logging data instead of doing their jobs
Muller concludes The Tyranny of Metrics with a useful checklist of ten questions that any manager should ask when considering the application of metrics at work.

Goodhart's Law: "When a measure becomes a target, it ceases to be a good measure."
