DL IN CONTEXT

--> Content
--> Using
--> System
--> Management


CONTENT

Who/how creates/ed
Who/how selects/ed
Who/how organizes/ed

(For these, context is related to goals and policies)

Why
How understandable
Coverage -- completeness, depth
Bib/fulltext/multimedia -- representations
Metadata, catalog, finding aids
Taylors dimensions: accuracy, currency, validity


USING (depends on theory -- those organize, include/exclude)

PURPOSE

Compare, improve systems, design process
Promote use, acceptance
Understand impact
Understand viability
---cost effectiveness
---DLs
Satisfy management (accountability)
Carry out: IR, HCI, Hypertext, design, DB, MM ... research
Check goals, usability
Verify, validate design/requirements


GOALS

Evaluate if service, use, etc. (or, indicators/metrics for service and use, etc.) are met/supported


OUTCOMES
Performance
  Purpose specific
    --Learning

Knowledge/technology transfer
  Adoption
  Adaption

---------
Viability
Rewards and punishments
Participation
Profits/benefits
---------

Goal migration      |  Series of failures accumulating
Change in practice  |

Meta issue: levels

Matrix (from purpose, goals, objectives)
  Or tree?
  Correlations?

MEASURES

Acceptance of DL by organization with respect to goals
Acceptance by users with respect to goals
Effectiveness of system with respect to tasks
Ability of users to understand system during use (fn: knowledge, ...)
Traffic
No. of users (people, institutions)
No. of searches, links
Time on task, errors
Substitution effects (e.g., for paper)
Complementary effects
Repeated use
Satisfaction
Amount of help needed, training needed
Unintended uses/serendipity
Time sinks (where time gets used, wasted)


PROCESS

Time
Instruments to help
Tutorials on ...

(The above three items are needed for various approaches)

Sustainability

Predict/test
---For various time spans
---On users, organizations
